''This page is about the history of China until the establishment of the People's Republic. For the history of the People's Republic of China specifically, see [[People's Republic of China#History|History of the People's Republic of China]].''

The history of China dates back to more than 5000 years ago. China, like all state societies, went through the [[slavery]], [[Feudalism|feudal]] and [[Capitalism|capitalist]] modes of production until the establishment of the People's Republic in 1949.

== Geography of China ==
[[File:China-topography-features.jpg|thumb|304x304px|Topographical map of China showing the Yellow river (in the North) and the Yangtze river (in the south)]]
According to Dr. Ken Hammond of the New Mexico State University, to understand how China (''Zhōngguó,'' 中国, literally the "Middle Empire") materially developed throughout its history, it's important to understand the geography of the country.<ref name=":0">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 1: Geography and Archeology|publisher=The Teaching Company}}</ref>

The North China plain, at the mouth of the Yellow river (''Huáng Hé'', 黄河), is to this day the agricultural heartland of China thanks to its low and flat terrain as well as the irrigation it receives from the Yellow river, and this plain is where Chinese civilisation first emerged.

Conversely, the South China plain is a region of hills and valleys, mostly south of the Yangtze river. Settlements in the south are divided off one another by these mountains, and river valleys tend to be where permanent settlements developed.

=== Rivers ===
Two important Chinese rivers find their source in the Tibetan plateau: The Yellow river and the Yangtze river.

The Yellow River has shaped China for millennia. It snakes around Northern China until it empties into the Yellow sea, in the province of Shandong. While the Yellow River has historically represented a challenge to China as it was prone to flooding, these floods brought with them fertile soil and irrigation to crops, and the river has always been primordial to the development of Chinese civilisation.

The Yangtze River (''Cháng Jiāng'', 长江, literally "long river") further in the south has also been very important to Chinese civilisation historically, but less so than the Yellow river. The Yangtze river, while prone to flooding both historically and in the modern day, has played a huge part in agriculture and sustaining life around it. The Yangtze river's flooding was dealt with in part through the Three Gorges dam.

== Prehistoric and early historic period ==

=== Traditional Chinese historiography===
Chinese history has been studied by its people since Ancient times, and forms the basis of the traditional Chinese historiography. Their history begins around the time of the sage kings, or sage emperors (), figures of antiquity and prehistory (i.e. that predate writing). Thus historiography, which is the writing of history itself, has been going on in China for millennia. Dr. Ken Hammond notes that in many places, this historiography has been proven correct thanks to archeological records found after the fact.<ref name=":02">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 3: The Zhou Conquest|publisher=The Teaching Company}}</ref>

==== Sage kings Yao and Shun====
A notable king in traditional Chinese historiography is Yao (尧), who was the first to pass the throne down to a successor. Yao's own son was considered to be weak and decadent, and so Yao scoured his kingdom until he found Shun (帝舜) who had strong moral virtues and picked him as his successor.

The story of king Yao is an interesting contrast to the practices of succession in other historical dynasties in China, where succession was kept to a single family. According to Dr. Ken Hammond, this story is important in Chinese historiography because it highlights a quality, having a strong moral character, that was considered important in Chinese history.<ref name=":02" />

This story, as well as the virtue of morals, would later found the premises for the [[Mandate of Heaven]] (''Tiānmìng'', 天命, literally Heaven's command) in China.

===Early societies===
[[File:Longshan-black-pottery-vase-7480.jpg|thumb|330x330px|Longshan black pottery vase dated around 2nd millenium BC.]]
According to Dr. Ken Hammond, the population of China itself has evolved in complex ways.<ref name=":0" /> The earliest people who would later call themselves the Chinese (''Zhongguo ren'', literally ''People of the Middle Country'') lived in the North China plain. The earliest societies to emerge from this area were confederations of numerous tribal groups who defined themselves in contrast to those who were not Chinese, i.e. people who were not civilised. A number of terms exist in Chinese to define these people that are best translated to as "barbarians" in English (barbarians being what the Ancient Greeks similarly called any people who were not Greek).

Excavated pottery remains suggest that a single culture came to dominate the whole of the North China plain some 4000 to 6000 years ago. Characteristic pottery was discovered as originating from Dragon Mountain (''Lóngshān'', 龙山,), and later showed up in other archeological sites.

===Writing===
One key element that made this first Chinese society define themselves as civilised (as opposed to what they defined as their barbarian neighbours) was a system of writing, which their neighbours did not possess. There is not much transitional evidence to the emergence of writing in China. That is to say, archeological evidence shows that once writing appears in China, it showed up as a fairly fully developed system, suggesting that writing appeared fairly quickly.

===Mass migration===
As Chinese civilisation expanded, neighbouring peoples, particularly in the South, were either displaced or assimilated. The Vietnamese and Thai people, for example, formerly lived in southern China and were displaced as part of this expansion to the South.

Some of these populations were forced further west, on higher elevation, and have remained there since then. Today, they are generally called hill tribe communities, and many of these groups retain distinctive identities in China: they retain their own language, their own cultural practice, and their own religion. Today, they constitute around 5% of the population of China. There are 54 such officially recognized ethnic minorities in China

This process happened around 2500 to 2000 years ago.

== The first slave states==
The emergence of bronze was critical to China's future development. Bronze gave rise to an industry of mining, smelting, and shaping the metal into tools, weapons, jewellery, etc. which created culture in the various populations that inhabited what is now China. This transition from the neolithic to the bronze age also marked the transition from prehistory to history.

===The Xia dynasty===
According to Dr. Hammond, traditional Chinese historiography considers the Xia (''Xià Cháo,'' 夏朝) to be the first dynasty in Chinese history.<ref name=":1">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 2: The first dynasties|publisher=The Teaching Company}}</ref> The Xia however did not leave any written records, but did leave a clear demarcation to prior forms of societies before them. Interestingly enough, some scholars believe that the Erlitou civillization along the Yellow River was the sight of the original Xia dynasty.<ref>Allan, Sarah (2007). "Erlitou and the Formation of Chinese Civilization: Toward a New Paradigm". ''The Journal of Asian Studies''. '''66''' (2): 461–496. doi:10.1017/S002191180700054X. S2CID 162264919. 

pp 489 - 490</ref>

The Xia period began roughly around 2200 BCE. The Xia built palace architecture, large structures built on rammed earth platforms (compressed and firm layers of dirt), a method that would keep being used in China for the coming millennia. The Xia also saw the emergence of [[class society]]; as agriculture and pottery was creating a surplus of food, fewer farmers were needed, and a class of "non-farmers" (artisans, warriors, spiritual leaders and bureaucrats) emerged, forming the basis of Chinese class society.

Dr. Hammond theorizes that this emergent class of leaders solidified their power by performing rituals for the populace. The Xia's ancestors performed totemism, a practice in which animal spirits are associated with particular tribal or clan families. In the Xia dynasty, the worship of totems of one particular family was transformed into a royal ancestral cult. In other words, not only the spirits of animals, but the spirits of the ancestors of the present day rulers came to be seen as divine powers. This further solidified the power of the royal family and laid the foundation for [[Monarchism|monarchy]] in Chinese society.

The Xia civilisation ultimately did not leave many details as to their way of life, and most of their records came from the subsequent Shang dynasty, who shared many consistent features with the Xia.

===The Shang dynasty===
The Shang dynasty (''Shāng Cháo,'' 商朝), named after the royal family, begins around 1500 BCE. Dr. Hammond notes that traditional Chinese historiography uses a very elaborate and precise chronology which would place the Shang dynasty at 1766 BC, but that modern archeological investigations cannot confirm this date, and so the actual date of their foundation remains vague.<ref name=":1" />

==== Oracle bones divination ====
[[File:Oracle bone inscriptions.png|thumb|337x337px|The abdominal parts of two tortoise shells with divinatory inscriptions excavated at the site of Yinxu, Anyang, Henan, China.]]
The Shang dynasty has left many written records about their life, as they performed oracle bone divination (''jiǎgǔ'', 甲骨). In this practice, people would ask a question to the royal family's ancestors on either oxen shoulder blade bone or the underside of turtle shells. The question would be carved on the bone by a diviner, the class of people who could read and write. The bone would then be poked by a sharp, hot object during daily ceremonies, which caused it to crack. The way the bone cracked was then interpreted as an answer by the ancestors to the question carved into the bone. The Shang took their written records even further and kept records on the ''results'' of the divination. This means they kept record of not only the questions, but also the answers and actual outcome of the divinations.

Oracle bone divination was so commonplace in the Shang period that to this day, tens of thousands of bones have been dug up.

Dr. Hammond notes that these divination rituals were important to maintain the power of the dynasty and diviners, but the bronze culture was also equally important. Bronze cutlery (such as wine cups, plates or pans) were used to present offerings to the ruler's ancestors. After these offerings and sacrifices, which took place in great halls, the king would offer the "physical remains" (the offerings that had not been consumed by the ancestors) to the populace in great feasts, as a way to remind the people of his wealth and power.

==== Succession of power ====
The Shang dynasty had a novel way of handling succession. In their time, life expectancy was not very long -- one could hope to live up to 30 on average. It was thus very common that the Shang king would die before his oldest son was old enough to succeed him. Because of this, the kingship passed from oldest to youngest brother. Then the eldest son of the eldest king would take over, and the process would repeat. 26 kings were recorded during the Shang period. which lasted for around 500 years (an average of one king every twenty years).

The Shang also built royal capitals, which was a continuation of the Xia palace architecture on rammed earth structures. However, they didn't seem to stay in them a very long time: they had nine capitals during their 500 years rule. These buildings were bigger and more decorated than their Xia predecessors, likely as a way to display their wealth and power.
==== Shang state ====
[[File:Approximate territory of the Shang dynasty.png|thumb|Approximate territory of the Shang dynasty, in green.]]The Shang state was a federation of people. In other words, there was the Shang ruling family, their blood relations, and then people who were not blood relations to that family but were part of the Shang state. The Shang dynasty spread relatively far, and the federated people that were part of this state played a primordial role in its upkeep and border security. As such, due to the size of the Shang empire, reports, letters and communication from the king to his subordinates would be sent in writing, which characterises the Shang as a literate state.

The Shang state was quite elaborate and practised division of labour from early on. Bronze objects, for example, were made with casts in which molten bronze was poured in. Their bronze industry -- mining the metal, smelting, refining, blending the metals together, the design of the objects, etc. was all organised by the Shang state and required different labourers and artisans for each step of the process. That involved the organisation of a consequent number of people as well as running activities at a number of sites (the mines, for example, were not located in the same place as the furnaces).

This elaborate, organised system of production required that the Shang state had a capacity to sustain its people, e.g. feeding them, clothing them, housing them, etc. This is how archeologists know that the Shang also had an elaborate taxation system, which also appeared on oracle bones. Tributes were paid by subordinates who were part of this federation to the Shang royal family and formed the basis of taxation revenue. Furthermore, the organisation of the mining industry further established the authority of the royal family and their kin.

The Shang practiced [[slavery]], which was the first major mode of production in the world and allowed them to sustain this elaborate society and state. Slaves, as was usual in the earliest incarnation of the institution, were usually prisoners of war and criminals.

==== Decline of the Shang period ====
The people not under Shang authority were a constant concern and often came up in oracle bones. Since the Shang recorded every outcome of oracle bone divination, these records show that there were frequent devastating raids from outside populations. Notably, people were recorded as being taken away as slaves during these raids.

Security was a critical function of the Shang state but eventually found itself in a contradiction. The Shang dynasty needed to deploy and maintain soldiers in the border regions, where the tributary non-Shang people lived, so that they could receive their tribute and not have it stolen during raids. Over time, this created resentment from these populations, especially when security started breaking down and raids became more frequent.

This unrest eventually boiled over to rebellion, when the tributary peoples to the Shang overthrew the dynasty and established the Zhou dynasty as their successors.

==Western Zhou==

=== Premises ===
The Zhou people (''Zhōu'', 周), located on the western side of the Shang Empire, were a tributary community of the empire, with a mythological history of their own. Their early history involves a change from a hunting-gathering society, before developing to an agricultural society, going back to hunting and gathering, and finally settling down as more permanent farmers. According to Dr. Hammond,<ref name=":02" /> these societal changes reflect the environmental conditions at the time (some 4000 years ago), when northwestern China was wetter, cooler, and the weather had not settled permanently, which made food sources change over time.

After the Zhou settled into sedentary agricultural communities, they became affiliated as a tributary state to the Zhou, a process that left them resentful of their new lords. Around the late 12th century BCE (-1150), as the Shang dynasty was facing external raids they could not defend against, the Zhou leaders decided that the Shang were unfit to rule and they should replace them.

One notable advancement of the Zhou dynasty was that they marked a break way from slavery and into early [[Feudalism|feudal]] society (Fēngjiàn, 封建) which worked differently from the European feudal system to which we owe the name.

=== War against the Shang ===
Tai Zhou articulated this ambition which his people carried out over the the next three generations. The Zhou people followed the Wei river eastward and resettled closer to the Shang. Secondly, they sustained greater communication with other subordinated people of the Shang Empire, particulary on the west side of the Shang territory so as to create the alliances necessary to overthrow the Shang kings. Finally, around the year 1050 BC, the Zhou initiated a war against the Shang. According to Dr. Hammond, the war seems to have been initiated by Wen Zhou, referred to as a king in historical records, but his son king Wu was the one who took the throne from the Shang.

While the exact date of this war has been lost, paleoastronomers have narrowed down the range of possible dates to within a few years of 1045 BCE based on the study of celestial events described at that time.

On that date, the Zhou people and their allies marched to the capital of the Shang (modern day Anyang), and set themselves up on the west side of a river. On the morning of the battle, the young king Wu gave a speech calling for the overthrow of the Shang and then led his armies forward into the city. A number of ancient documents that have survived to this day describe the battle that took place on that day; the Classic of Documents contains a purported transcript of the speech king Wu gave on that day as well as a document describing the battle.

The battle concluded with the killing of the Shang king; the Shang state was thus seized by the Zhou and king Wu crowned.

==== The duke of Zhou ====
King Wu was still quite young when he seized the state from the Shang dynasty. King Wen had a younger brother, who is only known as the duke of Zhou in historical records, who then served as an advisor to the young king. He was seen as a very sage and moral character, as he could have easily usurped the throne from his older brother due to Wu's young age, but instead was happy to serve as an advisor.

The duke of Zhou thus became a very important figure in Chinese history, even serving as a model for Confucius some 500 years later.

=== Migration of the Shang ===
Although the Shang had been defeated, the Zhou did not exterminate them. The Shang were moved away from the capital of Anyang to the south and east and given a territory of their own, made into subordinates of the Zhou. They were allowed to retain their customs, including the worship of their royal family's ancestors. To this day, certain families in southeastern [[Anhui]] province trace their family all the way back to the Shang.

=== Establishment of Chang'an capital ===
At the same time, the Zhou moved the capital (and thus center) of their empire from Anyang back to their own ancestral homelands in the valley of the Wei river. They built a new capital at Chang'an (modern-day city of Xian), which served as a capital for a number of later dynasties.

The Zhou also established a pattern for the design of capital cities which was later picked up by subsequent dynasties. Their city was designed to be the physical representation of a well-ordered world, drawing back to the Mandate of Heaven. The city of Chang'an was laid out as a square surrounded by a wall, and oriented on a north-south axis with a compound in the northern part that formed the residence of the ruler. In the southern part of the city were residential areas for the common people, markets, and other centers of activity for daily life. Surrounding the city in the four cardinal directions (north, west, south, east) were ritual complexes -- altars and other temples for the performing of sacrifices and other ceremonies.

=== Creation of the Mandate of Heaven ===
To understand the [[Mandate of Heaven]], it is important to understand what Heaven is in China. According to Dr. Hammond, the Chinese people in earlier history (including the Zhou) worshipped what we translate as Heaven (''tian''). Tian should not be thought of as the Christian Heaven, but rather sort of a natural operating system, the overarching mechanism that governs the functioning of everything in the universe. Tian should be understood as an all-encompassing organic system, and not as a divinity or god. However, it does have the capacity for action. One such capacity is the bestowing of the Mandate of Heaven, or the withdrawing thereof.

The Zhou were the ones to develop this doctrine to justify their conquest of the Shang, arguing that there is a "proper" way for society to be organised focalised around a good ruler. since the Shang were unable to protect them from raids (and thus did not maintain the livelihood and prosperity of the people), they were unfit to rule and Heaven (tian) had withdrawn the Mandate from the Shang and given it to the Zhou.<ref name=":02" />

The Mandate of Heaven would become central to all political transitions from one dynasty (or form of government) to another, even enduring to this day in the People's Republic. The Mandate formed instant justification for an overthrow of a dynasty: if one succeeded in seizing the state, then they had clearly received the Mandate of Heaven. If they failed, then they clearly had not received the Mandate and thus the old dynasty would keep ruling.

For the first time, the state was not the property of a ruling family but instead, drawing on earlier mythical accounts of kings Yao and Shun, considered to be something that involved the moral qualities of the rulers. The Mandate is bestowed and removed by forces outside of human control, and as such the state belongs to the dynasty that was picked by Heaven to rule.

== Eastern Zhou: Transition from slavery to feudalism ==

=== Early successes ===
The first two to three hundred years of Zhou rule were successful; that period was marked by territorial expansion (particularly in the south and southeast) and population growth. By the 8th century BCE, the Zhou state was four times larger than the territory controlled by the Shang at the time of conquest.

These successes lead to new administrative challenges. Governing the entire realm from the capital became difficult as it grew due to the sheer distance to cover, and the Zhou kings started delegating power to members of the royal family: brothers, cousins, etc. were sent to these regions to fulfil administrative roles.<ref name=":03">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 4: Fragmentation and Social Change|publisher=The Teaching Company}}</ref> However, the Zhou soon ran out of family members to appoint and turned to military leaders, loyal to the dynasty. The practice in the Zhou kingdom was that the military commander who brought new territory to the state would be appointed its political supervisor.

In the first few reigns of Zhou kings, this system worked well. The Zhou could appoint loyal individuals and let them take care of administrating remote regions on the border of the kingdom.

=== Administrative challenges ===
As time went by, the monarchy became an established institution -- not solely dependent on a moral king, but on the entire royal family. Members of the Zhou clan, who grew up in the royal capital, knew that they would be given a title to administrate eventually, and became complacent about it. At the same time, in local communities around the kingdom, the delegates managing these territories were the descendents of the original appointees, and thus they did not feel loyal to the Zhou dynasty, whose presence in these regions was almost null; they resent that they have to send taxes and tribute to the capital. This sentiment was particularly strong in the fertile southern and southeastern areas that produced a lot of food, but still had to send most of their surplus to the king as tribute.

Thus these local rulers started to hold back some of the tribute they were supposed to send, while at the same time subverting the established hierarchy; records show, in fact, that at the beginning of the 8th century BCE, certain local administrators (appointed by the Zhou royal family) begin to refer to themselves as kings instead of dukes, most notably in local official documents.

=== Arrival of the Qin and moving of the capital ===
In normal times, as the Zhou king heard of these developments, he would have sent troops to restore his authority on these tributary provinces. However, at the start of the 8th century BCE, a new people emerged from the western frontier of the Zhou kingdom, called the Qin. They started to raid into Zhou territory, which prompted them to move their capital far eastward, at the site of what is today the city of Luoyang, which remained a very important capital and cultural center for later dynasties.<ref name=":03" />

This move to a more secure area, which made the Zhou abandon their ancestral homeland in Chang'an. Because of this, the Zhou were unable to attend to the matter of local administrative appointees proclaiming themselves as kings, which was a challenge to the rule of the Zhou; as more local rulers proclaimed themselves king over their appointed lands, the legitimacy of the Zhou rule was called into question.

The crisis took several centuries to mature: despite the challenges, the Zhou dynasty remained on the throne and ruled from Luoyang. While tributary rulers kept paying some amount of respect to the Zhou dynasty, it became clear that the Zhou did not control any territory beyond their capital.

== Spring and Autumn period ==
From the middle of the 8th century BCE to the 5th century BCE, China saw the Spring and Autumn period develop. This period gets its name from the book of the ''Spring and Autumn Annals'', a record that described the year to year events happening in the tributary state of Lu.

The rulers of Lu claimed that they were descended from the duke of Zhou, which gave them some legitimacy on the throne over other minor states vying for power. The state of Lu was also the homeland of Confucius, whom is believed to have edited the ''Annals''.<ref name=":03" />

The Annals describe a process of sheer breakdown of the Zhou authority. As local rulers start calling themselves kings, so do they start acting like one: they set up royal courts in their holdings, they begin to perform rituals which are normally reserved for the king, they start to wear the clothing appropriate to a king, they demand the ritual gestures from their advisors that they themselves should show to the king, etc.

=== Rise of the hegemons ===
With the breakdown of their single, unifying authority, it becomes impossible for the Zhou kings to restore order in the kingdom. Self-proclaimed kings started conquering their neighbours, and the kingdom erupted into war rapidly after that. In Chinese records, these kings are called ''ba wang'', translated as hegemons, understood as "kings in power, but not in right". In other words, these kings were able to rule because they had the power to do so, but were not legitimate rulers as they had not received the Mandate of Heaven, still with the Zhou.

This period lasted a few hundred years and saw the number of states increase in China; from a single unified state in the 8th century BCE, there were more than 250 existing by the 5th century BCE, some of them consisting only of a single town and its agricultural fields. Each of them, no matter their size, claimed to be a legitimate sovereign government. While they still acknowledged the rulership of the Zhou to some extent, this was only a performative exercise as the Zhou kings exercised no real authority outside of their domain.

== Hundred schools of thought ==
{{Main article|Chinese philosophy}}
As this breakdown process took place over China, a new class slowly emergeed: the ''shi'' (士, meaning advisor, scholar or general), a class of professional political administrators and advisors to kings and rulers. Their role was reminiscent of the diviners of the Xia and Shang period, who could read and write, but was wholly a product of the situation at the time: as the number of royal courts proliferated, there came a large demand for capable administrators and advisors. The ''shi'' travelled the land offering their services to different kings for a period of time, often creating fierce competition between kings for the most capable advisor. Often, they became a symbol of a ruler: a king who had a famous or capable advisor at his side was regarded as a good ruler.

The proliferation of this class also gave rise to philosophy in China (and thus Chinese philosophy), as the ''shi'' would debate each other and, in this era of great turmoil and war, began to question the fundamental order of China and rulership to understand why the Zhou kingdom broke down, and how statesmen could avoid this fate in the future.<ref name=":04">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 5: Confucianism and Daoism|publisher=The Teaching Company}}</ref>

Their influence on Chinese society was such that they survived in various ways in later dynasties, and so many of these schools of thought existed that they are today referred to as the "hundred schools of thought" (''zhūzǐ bǎijiā'', 諸子百家).<ref name=":05">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 6: The Hundred Schools|publisher=The Teaching Company}}</ref>

Some of the most famous ''shi'' of this period are Confucius, Laozi, and Sun Tzu.
[[File:Confucius, fresco from a Western Han tomb of Dongping County, Shandong province, China.jpg|thumb|Likely the earliest depiction of Confucius, from a Western Han (202 BCE - 9 CE) fresco, found in a tomb in Shandong Province, China.|287x287px]]

=== Confucius and Confucianism ===
[[Confucius]] (''Kong Fuzi'', 孔子), was a ''shi'' and perhaps the most influential figure in Chinese philosophy. He was born in the Lu state circa 551 BCE and died in that same place around 480 BCE.

Most of the information that survived about Confucius was written down by his students and their students later on, but very little is known from his contemporaries.

Confucius grew up in the state of Lu and later spent a fair amount of time travelling around eastern China as a ''shi'', offering his services to various rulers. However, Confucius was not very successful in this effort and only landed minor roles and positions as an advisor. He eventually gave up on his goal of trying to achieve political success through serving in administrations. Confucius went back to his home state of Lu and settled into the role of a teacher.

The core of his ideas were about human relationships; if one wants a well-ordered society in which people can live together in peace and prosperity, then he argued people needed to realise that this happened through relationships with one another. He saw the family as a microcosm of this societal relationship: they involved on the one hand bonds of duties and obligations, and on the other bonds of affection and compassion.

==== Five great relationships ====
Confucius defined a set of five great relationships, concrete examples which represented his overarching idea of all relationships in society. These are the relationship between the ruler and the subject, father and son, husband and wife, elder brother and younger brother, and finally the relationship between friend and friend. All of these relationships have certain characteristics; in each pair, one side plays a "leading" role and one plays a "following" role, even in the friend relationship: according to Confucius, there will always be a set of circumstances that puts one friend as a leader above the other (age, skill, etc).

While there is a hierarchy in these relationships, they also have an aspect of reciprocity: the ruler (or father, or husband) must be a good ruler; they must fulfil their role in a proper way. If they abuse their role, then the subject (or the son, the wife, etc.) is "released from the bond of obligation. The reciprocity of these relationships is what makes them work according to Confucius, and differentiates them from a simple domineering relationship (where the ruler would just force the subject to comply to his will). If both sides are fulfilling their roles properly then, according to Confucius, society will function properly.<ref name=":04" />

These relationships structure society, but to make them work people need to understand this system as they encounter it so they can apply it. To make that happen, Confucius relied on ritual: he saw rituals as central to the implementation of his order of relationships in daily life. Rituals are simply repeated behaviour and can be as simple as a handshake (when two people meet, they shake hands) or as elaborate as a graduation ceremony, which involve hundreds of people.

==== Analysis of the Zhou period ====
When looking back at the decline of the Zhou period, Confucius attributed its downfall to the violation of the proper ritual order: when people started taking for themselves the title of king and performing the rituals of royalty at their court, they broke with the right way of ordering society and all the wars and suffering that afflicted China since then stemmed from that fact.

To fix this situation, Confucius argued for the return of the ritual order of the early Zhou rather than the chaotic disordered of the warring states period. He also advocated for the rectification of names or in other words, to "make names fit reality" (going back to the rise of the Hegemons who usurped the title of king).

A critical individual in this process of rectification is what Confucius called the gentleman (''jūn zǐ'', 君子, literally "noble's son"). This individual is one who models the proper ritual order and behaviour in himself: he engages in learning about the past, and he seeks to approach the Dao (道, meaning "a path"), i.e. the way one should live in the world to manifest the rectification of rituals. As a role model, the gentleman can be emulated by others in society.

Around 150 years after Confucius' death, a man by the name of [[Mencius]] (Meng Ke, 孟軻) picked up his work and developed Confucius' ideas further. Mencius especially turned his attention towards the relationship between a ruler and his subject, talking about the necessity of the ruler to "do the right thing", and that the people had the right to overthrow him if he failed at this duty.

=== Daoism ===
Daoism (or Taoism) was theorised by Laozi (Lǎozǐ, 老子, also romanised as Lao Tsu meaning "old master") and was as important and influential as Confucianism in traditional Chinese society. While Confucianism had a very proactive outlook (society will prosper if people act towards the natural order), Daoism is radically at odds with Confucianism. It is based upon a skepticism of our knowledge and epistemology (the ability to know things).<ref name=":04" />

Not much is known about Laozi, and it is not sure that he even existed. His most famous work is a book that bears his name, with most subsequent writings being attributed to a later follower by the name of Zhuangzi who wrote around the 3rd century BCE.

For Daoists, all knowledge is arbitrary and partial. When we think about knowledge, all we're talking about is our ability to communicate: we know something is an orange, for example, because we name it an orange; names are meaningless and made up to describe things existing in reality. Thus our knowledge, Daoists argue, is partial: it is always limited and one can never know everything.

Acting on the basis of partial knowledge will lead to consequences which can't be anticipated; in trying to make things better, we often end up making them worse.

Zhuangzi liked to write in fables to explain his teachings, and one such fable is of an eagle soaring high in the sky who can not discern between individual rocks and trees, it just sees patterns of colour on the ground. By contrast, a little sparrow is hopping around on the ground and sees everything up close: the individual grains in the stalks of wheat, the leaves on the trees, the gravel on the road, etc. According to Zhuangzi, neither one is right in their interpretation of what they see as they're limited by their perspective. This fable illustrates the fundamental Daoist belief of questioning one's ability to know things.

Daoists were of course worried about the troubles facing China, and in fact Laozi wrote about his vision for a well-ordered society. In his opinion, an ideal life is one in which everything one should want and need is already found in one's immediate community. Thus, wanting to conquer other states does not lead one anywhere, all it does is take one out of the proper order where one really belongs. A critical concept in Daoism is ''wu wei'' (translated as "inaction") -- what it means is not to act in a way that goes against the natural flow of things or being.

For Daoists, the point isn't to make the world a better place (because one cannot know all the necessary information to achieve that goal), but to live in one's own proper order.<ref name=":04" />

=== Other schools of thought ===
Confucianism and Daoism thus were at opposites. While the former advocated human action, the other advocated skepticism and inaction. These two schools of thought, while being the most influential in Chinese society, were not the only ones existing at the time of the warring states period however.<ref name=":04" />

Many of these schools were concerned with linguistics, and humankind's relationship to words in the material world. Others were concerned with military strategy, which made sense during a time of chronic wars. Sun Tzu (''Sūnzǐ'', 孙子) is certainly the most famous military thinkers to come out of the warring states period and was in great demand back in his time as well, unlike Confucius who had trouble finding employment as a political influencer. Other thinkers also explored cosmology or [[metaphysics]].

Two significant theories of this era, which did not survive as influential schools after the warring states period, were Mohism (''Mòjiā'', 墨家 named after its founder ''Mòzǐ'', 墨子) and Legalism (''Fǎ Jiā'', 法家).

==== Mohism ====
Mohism is remembered for two aspects of its school: the doctrine of universal love and defensive warfare.

Mohists believed that one should love everyone equally and treat other people the way one would like to be treated. While there are some parallels to Confucianism (for example, Confucius' famous silver rule "do not impose on others that which you yourself do not desire"), the Mohist doctrine of universal love developed as a critical response to the Confucians' theories of reciprocal relationships, especially how some relationships were more important than other. The Mohists argued that the priority given to one's family were the vector of war as ruling dynasties were themselves a family, and thus put their family's interests above other rulers'.<ref name=":05" />

The Mohists, following their doctrine, also became renowned experts in defensive warfare. Their idea was that by building up the defences of smaller and weaker states (so that they could resist the attacks of stronger states), then aggression would cease to be a profitable course of action and they would stop fighting -- and instead pursue their interests by other less violent means. The Mohists offered their services as consultants to states which were at risk of being invaded, and in some cases proved to be quite effective (but obviously did not stop warfare entirely as the warring states period continued).

The ideas of Mòjiā faded away as the warring states period came to an end, as they were a product of this period and ceased to be relevant in the time of peace that followed.

==== Legalism ====
Legalists had an approach on politics, government and social order that was rather different from any other schools of the time. The doctrines of legalism are associated particularly with the state of Qin -- the same one that forced the Zhou to move their capital and led to their decline soon after.

The Qin developed a very effective military state; the whole of their society was mobilised and directed towards the objective of expansion. These methods began to be formulated during the 4th century BCE by Shang Yang (''Gōngsūn Yǎng'', 公孫鞅) who was the chief minister of the Qin state at that time. His basis was quite simple, and revolved around rewards and punishments.

On this basis, Shang Yang began a process that went on for over 150 years of promulgating laws, codes and regulations which gave the people in Qin society a clear understanding of what their obligations and duties were and what the consequences of failing those laws were. The idea was that by having clear laws that everybody knew and understood the consequences of breaking, then people would behave properly. The Qin proved to be truly effective in this regard, as the laws were applied equally to everyone regardless of class or status: the punishments applied to anyone who broke the law, whether they were a farmer or a general. 

These laws were fairly harsh; punishments often involved amputation, execution or banishment even for relatively minor offenses. In theory, the harshness was mitigated by the fact that everybody knew the punishments for breaking the law.

In the 3rd century BCE, Han Fei (''hán fēi'', 韩非 ) developed a philosophical rationale to legalism. He himself was a ''shi'', and had worked in a number of courts before coming to the employment of the Qin for the remainder of his life. He developed a theory of human nature, theorising that people are naturally selfish and greedy and will seek to maximise their own personal gain and minimise their pain. In theory, by exploiting this nature, it is possible to get people to do what one wanted them to do. This theory is interesting not only because it draws parallels to modern-day [[Neoliberalism|neoliberal]] arguments and justifications, but also because it broke away from other schools at the time (such as Confucianism and Mohism) who claimed there was a natural proper order to the world and people should perform their proper roles. In legalism, the state exists for the ruler: the ruler owns the state as his private property and there is no reciprocity like in Confucianism. Thus the state is not wielded as a tool to achieve the greater good, but to do what the ruler wishes.<ref name=":05" />

The doctrines of legalism served the Qin state very well during the warring states period, as they emerged victorious after defeating the last remaining state of Chu and unified China once again under a single dynasty.

== Warring states period ==
[[File:Warring states of china and Qin contest, circa 250 BCE.png|thumb|356x356px|In red, the territory controlled by the Qin in 210 BCE as they emerged victorious of the warring states period.]]
Around the year 480 BCE, the breakdown and fragmentation of China begins to reverse as strong states emerge and start to conquer weaker states. The number of states went from 250 to about 50-100 in just three centuries. This marked the end of the Spring and Autumn Period and the beginning of the Warring states period.<ref name=":04" />

=== End of the warring states period ===
Around the last decades of the period, starting at the 3rd century BCE, the Qin state collected victory over victory and quickly annexed the various remaining states, until only two were left: Qin and Chu, both controlling similarly-sized areas. The ruler of the Qin state was named Qin Shi Huangdi in Chinese historiography, meaning the first emperor of the Qin. This marked the moment the term Emperor (Huangdi) entered the Chinese vocabulary. This was a very significant act, as previous rulers were called kings (wang). Huangdi was an ancient mythological figure, from back in the age of Yao and Shun, almost a spiritual or god-like figure. The king of the Qin adopting the title of Huangdi was a claim to a type of rulership that had not been seen in China previously; it was a claim to total power over all of China, the lord of all.<ref name=":05" />

== Qin and Han: Growth of feudal society ==
The title of Qin Shi Huangdi, Dr. Hammond notes, was quite ironic, as the Qin state only ruled for 14 years.<ref name=":05" /> In that time though, they undertook dramatic transformations: controlling vast territories bigger than had been owned before by earlier dynasties.

Within his kingdom, the emperor set out to create a single administrative system. His work persisted after the Qin dynasty itself collapsed and into later dynasties.
[[File:Qin Coin.png|thumb|Preserved Qin dynasty era coin]]
The first such reform was of standardisation. When China had been divided in the Spring and Autumn and then warring states period, local circumstances had diverged quite a bit from kingdom to kingdom. For example, wagons and carts had axles of different lengths in different states. This seemingly innocuous difference force traders to switch carts at the border, as the roads were not meant for different sized carts, and while this was highly beneficial to the warring state period (as the lords could restrict and control trade more easily), it created logistical delays in the unified Qin state. The Qin axle length was standardised by Qin Shi Huangdi over the entire empire. Standard coins were also introduced in the empire, and the Qin state was the first to give Chinese coins a square hole in the middle so they could be linked on a string. Qin Shi Huangdi also standardised writing across the whole empire, normalising how characters should be written.

The Qin also thought it important to establish a standard ideological system. They were not particularly attached to the ideas of Confucius or other great thinkers like Laozi: only the doctrine of legalism counted. This led, in the year 214 BCE, to a burning of books and the burying of scholars. Any books that were not teachings of legalism or practical utilitarian texts (how to do things) were destroyed. Likewise, as many teachings were taught orally by teachers and thinkers, the Qin emperor ordered that these scholars who knew the texts by heart be buried alive. This process was very thorough, and many of these texts did not survive this process, as most of them existed in only one copy at the time -- to this day, very few texts exist from before the fall of the Qin dynasty. Those that did survive were usually written down after the fall of the Qin dynasty.

=== Overthrow of the Qin ===
The doctrine of legalism proved to be a very effective system at gaining power, but not at ''retaining'' it. There was no method of self-regulation in this system, i.e. no restraint on how to wield power. Qin Shi Huangdi pursued this power purely in his own self-interest and died in 210 BCE.<ref name=":06">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 7: The Early Han Dynasty|publisher=The Teaching Company}}</ref> His son succeeded him on the throne, but proved unable to maintain the state his father had assembled, and he was killed only three years later.

In the five following years, several contenders emerged, trying to establish their dynasty over China. Fairly quickly, two principal contenders appeared: Xiang Yu (''Xiàng Yǔ'', 项籍), and Liu Bang (''Liú Bāng'', 劉邦). Xiangu Yu was a general in the state of Chu prior to the unification under the Qin state, and was the most likely contender for the throne as he proved very popular in the empire.

On the other hand, hist opponent Liu Bang (who did become Emperor of China) was a relatively minor figure; he was a jailer, escorting groups of prisoners from local jails to county jails. Around the time the Qin state was collapsing, Liu Bang embarked on one of this mission, which involved an overnight journey. He made camp with his prisoners in the night and, in the morning, found that several had escaped. He knew that this would have dire consequences for him as, under the Qin system, he had failed his duties and would be likely executed. To avoid this fate, Liu Bang resorted to the only other alternative available to him: he assembled his remaining prisoners and told them he would set them free if they followed him. They became the core of his rebel army who fought against the Qin and, after the collapse of the dynasty, he continued to raise an army which eventually grew to become a serious military challenger for power.<ref name=":06" />

Xiang Yu and Liu Bang eventually came into direct conflict with one another. In the year 204 BCE, there was a battle in which Xiang Yu defeated his rival, inflicting very strong casualties on Liu Bang's side, after which his army (and Liu Bang's struggle for the throne) was thought to have been destroyed. However, Liu Bang had executed a strategic withdrawal which led his army into a port town on the Yellow river (named Ao). There, he seized the granary, fed his troops, recruited new followers and rebuilt his forces to resume the conflict with Xiang Yu.

Two years later, Liu Bang defeated Xiang Yu in a very dramatic siege where. The story, in traditional Chinese historiography, was that Xiang Yu found his encampment surrounded by the soldiers of Liu Bang -- themselves former soldiers of the Chu -- singing folk songs of their homeland. When Xiang Yu heard the songs, he knew that his cause was lost. He had a final evening with his favourite concubine, killed her, and then leapt on his horse straight into the enemy's lines where he was finally cut down.

With his main opponent taken out of the power struggle, Liu Bang was free to proclaim a new dynasty over China, which he called the Han, after the district from which he was from. The Han dynasty became one of the great ages in Chinese history, lasting for 400 years, reaching a geographical size, population and wealth never seen before. The Han dynasty was a contemporary of the [[Roman Empire (27 BCE–395 CE)|Roman Empire]] in the west and the two indirectly traded through the [[silk road]].

==The early Han dynasty==
Liu Bang established the capital at Chang'an, the same city that was the first capital of the Zhou dynasty as well as the capital of the Qin empire. From there, he established a system of imperial governance which was at first a continuation of the Qin system but evolved over the next century of Han rule into a much more stable and viable order.

Liu Bang inherited however two systems of governance at the time of his ascension to the throne. The administration in the western half of China was run directly from the capital: the emperor appointed officials to serve in local government for relatively short fixed terms before being sent somewhere else. This allowed the imperial court and the emperor to exercise direct control and essentially administrate these regions himself.

In the eastern half of the empire, power was given to military leaders in Liu Bang's army who had secured these territories and pledged their loyalty to the new dynasty. This system had eventually led to the decline of the Zhou dynasty, and indeed became a problem as well for the Han dynasty.

Nonetheless, Liu Bang was able to stabilise his rule and peacefully handed the succession to his son after his death in 195 BCE. A challenge emerged soon, however, when the family of Empress Wu sought to develop influence at court. In 180, when the next emperor came to the throne, their plan was thwarted and the Liu family was able to keep control of the throne and push aside the Wu's ambitions.<ref name=":06" />

By that time, the military leaders who had been given land in the eastern part of the empire were becoming restless, and a number of efforts were made by the emperors to maintain and extend their control over the east. This came to a head in 154 BCE when a rebellion took place: several of the military rulers in the east rose up and challenged the power of the Liu family. Not all of them backed the rebellion though, and the Liu family was able to manipulate these rulers in the east against one another so that they fought against each other instead of against the emperor. As those regions weakened themselves, the empire was able to bring them back into their direct administration (following the system in the west) and use them as a base for operations against the remaining rebels. Within a few years, virtually all of east China came back under the direct administration of the Han.

This was a critical development: first, it indicated that the Han (and more globally the Chinese) had learned their lesson from the Zhou and how to counteract such situations. Secondly, it cemented the rulership of the Han dynasty: by 150 BCE, China was a single administrative entity, no longer divided by tributary rulers.

=== Emperor Wudi ===
The immediate aftermath of this period saw one of China's most famous emperors on the throne, Wudi (''Hàn Wǔdì'', 汉武帝 -- ''Wu'' being his honorific title and ''Di'' coming from ''Huangdi'', the title the Emperor of Qin established), who ruled from 141 BCE to 87 BCE -- his reign lasting for 54 years, making it the longest continuous reign in China at the time. Due to China being virtually free of internal strife and rebellion at the time of his ascension to the throne, Wudi was able to engage in many reforms that consolidated an imperial, administrative and ideological order which remained the basis of the imperial court for the next 2000 years.

This process started by emperor Wudi is often called the ''Han synthesis'' by historians, and is described as a blending together of three components: Confucianism, legalism (as an administrative practice) and metaphysics.<ref name=":06" />

The Han legal system was inspired by the Qin system of rewards and punishments, but was made more "humane" by the inclusion of a Confucian element, which sought out to establish proper relationships between people. These two philosophies were however more concerned by the [[Materialism|material]] world, and emperor Wudi was concerned with the metaphysical world as well, which he saw as an integral part (along with the material world) of a larger cosmic order.

This was theorised by the likes of Dong Zhongshu (''Dŏng Zhòngshū'', 董仲舒) who brought together a number of ideas that had been in China for a long time already into a system that is sometimes called correlative cosmology; correlative cosmology seeks to explain correlation and connections between phenomena that can observed in the natural world and actions taking place in human society. Dr. Hammond likens it to a "doctrine of interpretation of omens": an earthquake or an eclipse, for example, may be interpreted as a sign that the natural order of things is disturbed in some way. Human misbehaviour -- including the emperor's -- would create such omens which were interpreted by the royal court to bring the emperor back on the right path.

Wudi had a vision of the state that was in agreement with Confucianism as a tool for doing good, but this vision was also a rationale for his many expansions: his reign is also marked with a period of great military expansions, going as far as invading Korea in the north, Vietnam in the south and projecting power to [[central Asia]], creating the largest Chinese empire at the time. Emperor Wudi famously apologised to the whole of China for the many wars he started near the end of his reign, which he considered a mistake.

His governing style was also new; he wanted the state to proactively solve problems for people and be engaged in the economic life of the country. He was against the manipulation of the market for mercantile profiteering and created government monopolies on critical goods such as salt, iron, alcohol, etc. to regulate and dispatch these commodities around the country.

Wudi also began the practice of [[meritocracy]] in the state administration, which survives in China to this day notably in the [[Communist Party of China|communist party]]'s internal structure. Under this system, the royal court held examinations (based on written tests) that anyone could take to demonstrate their scholarship and learning. Passing the test would let one be appointed to positions in government. This system was initially held at a very small scale, and was not the main tool for recruiting government officials in China: during Wudi's reign, most officials came into service of the government through reputation or recommandation.<ref name=":06" />

=== Aftermath of Wudi's reign ===
After Wudi's death, his policies came under debate: in 81 BCE, six years after his death, great debate at court took place at the royal court, surviving in written records known as the ''Debate on salt and iron''. Two factions formed, arguing over whether it was a good thing (in Confucian terms) for the state to intervene in the economy. One faction argued that the role of the state was to regulate private greed so the interests of the common people could be protected, and the other faction argued that the government shouldn't be intervening in society but merely create a set of moral expectations: the government itself should be good and act in a proper way, which would set the example for people in society to follow. They also argued that it was improper for the government to enrich itself by participating in private economic activity. These debates were significant in their time and were also studied by the later Chinese to set out the parameters of how interventionist or active the government should be.

The result of these debates was that the government decided to abandon most of Wudi's monopolies, and allowed the economy to go its own way with a minimal amount of government intervention.

This moment -- up until to around the turn of the millennium (and entrance to the Common Era) -- was characterised by a very stable period in China's history, at least for the people. During this time, the Han court became more self-centred; i.e. more concerned about its extravagant entertainments and social life. Emperors were less and less directly engaging in the affairs of administration, instead preferring to engage in leisure and leaving the management of the state to their officials. This allowed officials to become corrupt and line their own pockets. The revenue of the state was neglected, day-to-day administrative tasks were ignored, and so were military affairs. Additionally, in-law families (relatives by marriage) tried to manipulate the royal court in their favour.

== Later Han dynasty ==
This all came to a head in the year 7 of the present era when emperor Zhangdi (漢章帝) died without an heir. A brief period followed where power was usurped by Wang Mang (王莽) who headed the Xin dynasty (''Xīn Cháo, 新朝'', literally "new dynasty") for about 20 years. This period is known as the ''Wang Mang Interregnum.<ref name=":07">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 8: Later Han and the Three Kingdoms|publisher=The Teaching Company}}</ref>'' Wang died without a successor in the year 23 of the current era, and another branch of the Liu family re-established their rule. This event started the period known as the later Han (or sometimes the eastern Han) which lasted for another 200 years.<ref name=":06" />

=== Land reforms ===
The Han dynasty as a whole was a period during which the land ownership underwent significant changes.<ref name=":07" />

Up until that point, land had been the property of lords (most of them military rulers), and the farmers that lived on the land were the possessions of the rulers as well. Most of these rulers were put in place in earlier dynasties by rewarding generals with the land they conquered, but some land grants were made to members of the political administration as rewards for services rendered.

As the Han dynasty dealt with the problem of local military rulers and unified the whole empire under their sole command, their administration naturally moved to a more civilian staff and was expanded to help manage the affairs of a centralised realm. The Han then began attributing land differently, forced by the material reality of this new order in which they were the sole owner of all the land and did not rely on the loyalty of tributary lords. The practice of rewarding administrators with land became an institution under the Han.

This policy also changed the make up of the agricultural economy which started resembling a market system, where individual estates owned by individual families produced grain and other commodities which were then sold over the whole of China.

In theory, land remained the property of the emperor. In practice however, land that was granted out to families (and passed on from generation to generation) developed into ''de facto'' [[private property]]. The state actually started to recognize this fact and charters and other grants of land started functioning like deeds. Conflicts between landlords (such as access to water) were mediated through a legal court that recognized their property and title as land owners.

The advent of private property was a very significant event in the history of China, and would survive for millennia after that. Generational wealth began being amassed in a process which could be likened to [[Primitive accumulation of capital|primitive accumulation]].

=== Cultural shift ===
Given that the [[Base and superstructure|base]] changed, so did the [[superstructure]] of China. Chinese culture had, prior to the later Han, been focused primarily on tales of heroism and the glories of warfare, which were characteristic of the warring states period. The Han instead pursued cultural sophistication: learning and the pursuit of knowledge, being able to both read and write poetry, writing essays, became more culturally significant and valued in the later Han. This shift was spearheaded by the [[ruling class]] and mostly concerned them.

=== End of the Han period ===

==== Eunuch influence ====
Internal conflicts start reappearing at the royal court however, with in-laws trying to seize power at court, military leaders resenting this new class of landlords who, they feel, have stolen their titles, and eunuchs becoming a problem as well. Eunuchs were somewhat unique to Chinese society: they were castrated males who served in the private residential parts of the imperial palace. Their condition made them non-threatening to the line of succession, and while eunuchs were not unique to China per se, their specific role in imperial China was. Eunuchs also worked with the emperor's concubines, and in China non-eunuch males were not allowed to enter the residential part of the palace. Most of the time, eunuchs kept to their menial role but in times when the succession led to a young emperor on the throne, eunuchs could be influential over the young emperor who likely had one as his tutor or companion.

==== Decline of the Han ====
Eunuchs gaining influence notably became a problem in the later Han when a series of young emperors came to the throne, which turned them into a major faction within the imperial court.

Making matters worse, the weakening of imperial oversight allowed local strongmen -- not yet military figures, but mostly private land owners -- to intensify their exploitation over the peasantry, raising taxes and rents, creating discontent. Unsurprisingly, this situation led to the outbreak of rebellions against landlords and the dynasty over large parts of China. The empire responded by leading military interventions to quell these rebellions which, in a domino effect, increased the power of the military.

By the latter part of the second century, the Han dynasty had ceased to be a functional political entity. Much like the later Zhou, it still existed and emperors succeeded one another on the throne, but real power dissolved and strongmen in the country expanded their territory as factionalism at court weakened the functioning of the state even further.

Eventually, in the year 220, the last Han emperor was set aside and the country broke up into three successor states, one of which was ruled by a member of the Liu family (the ruling family of the Han dynasty), named Liu Bei (''Liú Bèi'', 刘备).<ref name=":07" />

==The three kingdoms period==
The breakup of the Han state led to the very short period (lasting from 220 to 265) known as the ''three kingdoms'' (''Sānguózhì yǎnyì'', 三国志演义), titled after the ''Chronicles of the Three Kingdoms'' (''sānguó zhì'', 三国志) written by Chen Shou (''Chén Shòu'', 陈寿) who lived through the period as a military officer of the Shu kingdom.

The three kingdoms in question were:

# Shu (蜀), in modern-day Sichuan province, ruled by Liu Bei of the Han dynasty.
# Wei (魏), situated in the north, ruled by Cao Pi (曹丕), son of Cao Cao (''Cáo Cāo,'' 曹操), a famous general of the late Han empire.
# Wu (吳), in the southeast, ruled by Sun Quan (''Sūn Quán'', 孙权).<ref name=":07" />

=== Beginning of the period ===
The three kingdoms period started in the same way the earlier breakdown of the Zhou had, by a fragmentation of the empire into various sovereign states. However, unlike the breakdown of the Zhou era, the three kingdoms remained stable among themselves and did not divide themselves. They all presented themselves as Confucian regimes: all three employed a Confucian administration and were concerned with doing good in their own states. Thus, there was still a continuity from the Han period -- with the distinction that the heroes of this era are generals and not scholars.

=== Significance of the three kingdoms period ===

It remains to this day one of the most famous eras in Chinese history due to the age it represents; unlike most periods of Chinese history, the heroes of the three kingdoms are not the kind of heroes portrayed in earlier times for their strength and might, but remembered their cleverness and wit. Deceiving your enemy, i.e. winning a fight by not fighting, are considered the great talents of this era. Cao Cao and Zhuge Liang (''Zhūgě Liàng'', 诸葛亮) are considered the two most exemplar heroes of this period.

In one instance, Dr. Hammond notes, a general had brought his army to the south, setting up camp on the bank of a large river. On the other side of the river were the enemy's forces. Their supply lines extended and arriving from a long march, the army in the north was in a tough spot for the coming battle. If they could inflict a decisive victory on their enemy at that time, however, they would certainly turn the tide of war. To make matters worse, the incoming army from the north had used up almost all their arrows in the battles on the way to the river. They thus decided to take advantage of the local conditions: in the evenings, a fog would come down on the river due to meteorological conditions at that time of year. Going upstream, they commandeered boats from the locals. In the boats, they built mannequins out of straw and put their uniforms on these strawmen. In the evening, they pushed these boats full of straw puppets down the river. The sentries of the opposing army suddenly saw several boats coming down the river, full of soldiers lined up to attack. They unleashed their arrows on the boats, hitting only the strawmen. Further downstream, the first army then brought the boats to shore and collected the arrows from the boats, resupplying themselves. Dr. Hammond notes this story is significant because it has been passed down for millennia, and remains told to this day. These stories have been dramatised into poetry, operas, novels and, more recently, TV shows in China.<ref name=":07" />

The Three Kingdoms period was immortalised and made famous by the epic novel ''Romance of the Three Kingdoms'' (''Sānguó Yǎnyì'', 三国演义) written in the 14th century by Luo Guanzhong (''Luó Guànzhōng'', 湖海散人). The novel is considered one of the four great classics of Chinese literature.

=== End of the period ===
In 265 CE, in the state of Wei, the Sima family seized power from the Cao family. They fielded a force which conquered the states of Wu and Shu, and from that time until the year 304, their dynasty of the Jin replaced the three Kingdoms and united China again.

That period of unification did not last very long however, as other events in Asia (which, Dr. Hammond notes, are still not fully understood) brought about a great migration of people around this time down into northern India. At the beginning of the 4th century, Turkic speaking people started moving into northwestern China.<ref name=":07" />

== Buddhism in China ==
{{Main article|Buddhism}}
Chinese history and culture is very largely self-contained, and so the arrival of Buddhism marked one of the rare moments when an outside element came into China.<ref name=":08">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 9: Buddhism|publisher=The Teaching Company}}</ref>

=== Origins of Buddhism ===
Buddhism traces its origins to India, at around the 6th century BCE -- the same time the teachings of the hundred schools are appearing in China. Dr. Hammond notes that this is a chronological coincidence which coincides with the appearance of other great ages of philosophy elsewhere in the world (such as in Ancient Greece or Persia).

There are plenty and very specific accounts around the origins of Buddhism -- stories about the life of Siddhartha Gautama, the first Buddha and founder of Buddhism -- but many contradict each other in certain aspects, which makes establishing a historical timeline of the Buddha's early life difficult.

The common thread to the origin of Buddhism is as follows: Siddhartha Gautama (also referred to as Shakyamuni, ''the light of the Shakyas'', his clan) underwent several life-changing experiences, and as a result of those became a teacher of new ideas which took root in India, developed and grew there, and eventually spread to the rest of South and Southeast Asia.

He came from a noble family in northern India (now in Nepal). As a noble, he grew up in conditions of great luxury and comfort. He was raised in a palace, and isolated in many ways from the realities of life around him. For the young prince, life was beautiful and a good thing to live.

At a certain point, he came to a realisation that not everything in the world is perfect and beautiful. In one account, the prince was out in the palace gardens one day, when he heard a sound he did not recognize. He climbed a tree near the wall of the garden, looking out onto the town street. There, he saw a procession of people going by carrying a plan with something wrapped in cloth and adorned with flowers. Not understanding what he was seeing, the prince went to his parents to ask them about this strange event. They explain to him that he saw a funeral procession; the wrapped up object was a dead body, and the sound he heard was the sound of crying and lamentation. This was the first encounter the prince had with death and the suffering associated with it; thus awakening him for the first time to the imperfections of the world.

There are a number of other accounts, but the common link between them is that at some point, before becoming the Buddha, Gautama saw or experienced something which made him understand imperfection in his previously perfect sheltered life.<ref name=":08" />

The prince then went out in search of understanding, to understand why there is suffering and imperfection in the world. He ran away from the palace and embarked on a spiritual quest which took him around the whole of northern India. This geographical area, Dr. Hammond notes, was very spiritually rich at the time: hermits were common in the woods, marketplaces were full of preachers, and the prince spent a number of years going from one teacher to another asking his question: why is there suffering, and is there anything we can do about it?

None of the teachers he encountered, however, gave the prince satisfactory answers. Eventually, he found a place called Sarnath (near the modern-day city of Varanasi, India). There, he went into a "deer park" -- likely an estate belonging to a family connected to his. While sitting under a tree, he suddenly had a moment of enlightenment and understood the answer to his question. Immediately following this event, the prince gave his first teachings. Following that event, he kept travelling and attracting more followers until the moment he realised he was soon going to depart the material world. Several accounts exist of what happened next; in one account, the Buddha bodily ascended to the celestial realm. In others, he left his physical body behind and spiritually transformed -- in those schools, there are relics of the Buddha's body. 

After his death or departure, the Buddha's followers took up the role of becoming his interpreters and teachers of their own. It was from that point forward that Buddhism grew and developed a religious practice and institution.

=== Teachings of Buddhism ===
In essence, the principles of Buddhism are very straight-forward. The key is the realisation of the nature of suffering; suffering is a part of our natural lives, and arises from our attachment to things in the material world. To be free of suffering, one has to free themselves from their attachments to the world around them. This can happen through meditation, renunciation and other spiritual undertakings.

These are the four noble truths and are the core to all schools of Buddhism.

The reason attachment is the source of suffering is that the reality of the world is impermanent: everything that exists passes away at some point; it has a beginning and an end. The ''appearance'' of permanence is an illusion (''maya'' in Sanskrit). Illusion doesn't mean that things do not actually exist, but that nothing is going to permanently, continuously exist forever.

The most central experience of attachment is our own selves; we are all attached to ourselves (and our lives). The idea of rejecting attachment is very straightforward in theory, but becomes understandably difficult to put into practice: it is almost impossible to detach oneself from their own life. This is why the spiritual practice of renunciation (through meditation and other practices) becomes very important to Buddhists.

=== Schools of Buddhism ===
In the centuries after the death of the Buddha, his teachings develop and eventually spread, and two major schools of Buddhism arise.

==== Theravada school ====
Theravada Buddhism is primarily focused on the attainment of individual spiritual liberation; it takes the teachings of the Buddha at their most basic level and is concerned with how each individual can attain enlightenment for themselves.

Early Theravada Buddhism sees the earliest development of monasticism (choosing to live in a monastery) as individuals renounce their involvement in society and leave behind the things which attach them to this world, including the very strong attachment to family and friends.

At first, Theravada Buddhists simply retreated from the world and became hermits or wanderers. But as time went by, groups came together not to form a society with formal rules and practices, but rather into "places of dwelling", places where they would usually gather together.

==== Mahayana Buddhism ====
About 300 years later, a second school of Buddhism began to emerge, called Mahayana (''great vehicle''). This school moved its focus away from individual spiritual liberation and towards the salvation of all sentient beings. In this school of thought, any being capable of consciousness will be conscious of its own mortality and of the world around it. Therefore, it will be subject to the suffering caused by attachment. Mahayana Buddhism believes that one can't be truly spiritually free so long as they know others continue to suffer.

Mahayana Buddhism introduced the concept of the Bodhisattva, a being who has reached a point of spiritual liberation: they could attain a state of transcendance as they have reached their individual liberation, but choose to remain in the material world to help other beings along the path of spiritual enlightenment.

=== Spreading of Buddhism to Asia ===
The spread of Mahayana Buddhism was linked in part to the embrace of Buddhism by king Ashoka in India. He ruled much of northern India and wanted to be a good king; he held spiritual debates at his court and decided that Buddhism was the best answer to the problems facing people. He erected pillars of stone to proclaim and promote the teachings of Buddhism around his realm, specifically Mahayana.

It was from his kingdom that Buddhism spread out beyond India and into the rest of south and southeast Asia. The school that reached these places was Theravada. Mahayana Buddhism tended to go north and west and into central Asia, picked up along the silk road: Buddhist monks travelled along the silk road, spreading their teachings.

==== Arrival of Buddhism in China ====
It was from this route that Buddhism arrived in China some time in the second half of the Han dynasty. When Buddhist monks arrived in China, they were welcomed at the court of the emperor: the Han emperor himself was a spiritual figure himself, dating back to the Shang dynasty and the worship of his ancestors. In that role, he was a patron to all kinds of spiritual practices.

When Buddhist monks arrived at Luoyang, they were given room and board and allowed to practice. But, at the beginning, they were considered more of an exotic curiosity; they were foreigners coming from outside of China, and their teachings were interesting, but different.

Eventually, as the Han state deteriorated into widespread misery and rebellions, Buddhism became more popular among the masses; this should not be surprising, as it was a time of suffering and as such a philosophy that addressed the origins of suffering and offered a path out of it proved popular. Buddhism rapidly took root in China from that point on and became a part of Chinese culture and society. The teachings were spread through texts brought from India and by the oral teachings of monks. In the late second century and into the third century CE, Buddhism became a popular religion in China (popular in that it was the religion of the people).

==Great migration to China==
After the short-lived Jin dynasty, and as Buddhism was spreading into China, a new force came into China from outside: a great migration of peoples from Central Asia moved into the Chinese heartland. This event was part of a larger series of migrations that took place all over Asia during the fourth century, but historians are not sure why that movement happened.<ref name=":09">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 10: Northern and Southern Dynasties|publisher=The Teaching Company}}</ref>

This period is called the ''northern and southern dynasties'' (''Nán-Běi Cháo,'' 南北朝'')'' in Chinese historiography, with the new conquerors forming the northern dynasties, and the Han people pushed south forming the southern dynasties.

The people that came to northern-northwestern China (relative to the borders at the end of the Han dynasty) spoke a language that is an ancestor to Turkish, and are sometimes called proto-Turkic by historians. They arrived in a space occupied by the Xiongnu people, who had been a constant presence and, at times, either a welcome trading partner or a threat on the Chinese frontier -- the Han dynasty build the Great Wall to defend against their raids.

When the Turkic peoples started migrating into the territory of the Xiongnu, who were nomadic, they became displaced and moved further up north. After a long migration that took them several decades, they emerged in European history as the Huns.

Eventually, these Turkic peoples moved from what was the Xiongnu territory and into China as well, which was a fertile area. Their migration came to an end north of the Yangtze river, which they did not cross. The north of China at the time was home to 20-30 million people, and the migratory populations totalled fewer than a million people. It should be understood that this process of migration was not peaceful and did not displace the Chinese people established there, but rather these newcomers established themselves as sort of overlords.<ref name=":09" /> In this process, they displaced the empire of China from the region and instead established their rule, taking over by force. This period is called the Northern dynasty.

South of the Yangtze river, Chinese civilisation and political order was preserved. However, Chinese presence in that area had only been established for a few hundred years at most; Dr. Hammond notes that the Chinese population in the south was aware that they were not living in their ancestral homeland.

=== Northern Wei dynasty ===
[[File:Southern and Northern Dynasties 440 CE.png|thumb|332x332px|Southern and Northern Dynasties 440 CE. The Wei dynasty came to dominate the north.]]
This process of migration only ended in the early 5th century, with many groups coming in at different times and establishing their rule of different areas. The most historically significant of these dynasties is the Wei dynasty (''Bei Wei'' 北魏) -- not to be confused with the Wei kingdom from the three kingdoms period (魏). To differentiate the two, historians often call it the Northern Wei dynasty or the ''Tuoba'' kingdom (拓跋魏), named after its people.

This dynasty controlled major parts of the modern-day Henan, Hebei and Shanxi provinces. They first established their capital near the modern-day city of Datong, and after a hundred years or so moved it to the historical capital of Luoyang.

==== Cave temples ====
[[File:5zmqouty.jpg|thumb|376x376px|Cave temple of Yungang (云冈, cloud harbour). The statues were originally contained in their own chambers, but the front walls eroded away with time.]]
The nature of the soil in northwestern China, called loess, is very particular. It is very granular soil built up by the retreat of the glaciers at the end of the last ice age, and the wind blew the resultant dust in fan-shaped patterns over thousands and thousands of square miles. The deposits of this soil can be hundreds of meters deep.<ref name=":09" />

Thanks to this granular nature as well as the dry climate of the region, it is possible to simply carve into it, and the people of north China often lived in dwellings carved out on hillsides.

The Tuoba built extensive Buddhist cave temples in the same way at each of their two capitals by carving out and hollowing into cliff faces. Some of the statues are 20-30 feet tall (6-9 metres), around which will be thousands of tiny Buddha figures. The statues were patronized by people to earn merit or as acts of devotion and faith; the bigger statues were commissionned by wealthy patrons such as the Wei lords themselves while the small status were ordered by farmers in exchange for a few coins to have it carved on their behalf.

Dr. Hammond notes that the cave temples show a clear mark that the Turkic peoples who migrated into China were themselves Buddhist (coming into contact with it after it had spread from India) and brought with them a somewhat militant form of Buddhism different from the one practiced in China.<ref name=":09" /> For the Tuoba and other Turkic peoples, Buddhism was central to their culture and had been devotees for centuries at that point.

==== End of the process of migration ====
The great migration into China went on for over a century and into the fifth century CE, but eventually stopped. Afterwards, another process followed where the new elite that had imposed itself in north China started to intermingle with the existing Chinese community. After having conquered the areas by military might, its rulers wanted to then control and extract wealth from its population; particulary because China produced items of great value (such as silk or porcelain) that were previously simply unavailable to these peoples.

From the point of view of the Chinese, particularly from the nobles and landowners, they were interested in forming alliances and partnerships with the conquerors to protect their interests. One principal way these two communites were able to come into contact with each other was through intermarriage.

Eventually, blended families emerged: they were neither fully Chinese or fully Turkic, but what anthropologists call Sino-Turkic. A process of cultural accomodation also took place at the same time, where the cultural practices of both sides were adopted -- mainly on the Turkic side.

The Turks quickly realised that to administer the territories they had conquered, they needed to use the existing mechanisms of local administration that the Chinese had laid out. Thus they adopted Chinese as the language of government, and shortly after adopted Chinese as the language of daily life. After a few generations, Turkic families started to adopt Chinese surnames adapted from their original name. Turkic leaders even began wearing Chinese-style clothing.

Likewise, certain Turkic words were adopted into Chinese vocabulary. Aspects of diet and food preparation became characteristic of north China, and some cultural practices of the region still practiced to this day can trace back their origins to the Turkic influences.

=== Southern dynasties ===
South of the Yangtze river, where the Chinese had been pushed out, there were also several different ruling dynasties. While the south of China had been controlled since emperor Wudi centuries earlier, the Chinese in the southern dynasties were very conscious of their Chinese identity. At the same time as the migrations happened in the north, thousands of people -- particulary wealthier families -- left their home in the north to move south, which reminded the southern Chinese of their "anomalous" position in the south -- that they were all migrants from the north.

==== Cultural developments during the southern dynasties ====
This engendered a kind of cultural anxiety that drove Chinese nobles to remind themselves of their cultural identity. One development was the rise of calligraphy as an art form; up until that point, writing had essentially been a functional practice: there had been prescribed forms on how to write characters (dating back to the Qin empire), but under the southern dynasties the ''way'' in which characters were written came to be seen as an art. The way one wrote, additionally, also came to be representative of their moral character. It was during the southern dynasties period that one celebrated calligrapher practiced, Wang Xizhi (王羲之). The southern dynasties also saw the emergence of painting as an art form. Prior to that period, painting was seen as a craft, the production of an item. But in the southern dynasties, painting was considered to be an expression of an artist' individual tastes. One famous painter of the period is Gu Kaizhi (''Gù Kǎizhī'', 顾恺之).

Writing as a literary tool also became increasingly complex. Chinese literature was very straight-forward and simple: writers like Mencius or Sun Tzu wrote in a very matter-of-fact, straight to the point style. Starting in the southern dynasties, writing became very self-referential; there were lots of allusions to earlier texts, sometimes maybe just a few lines or characters, often in obscure ways so that one had to be very educated and knowledgeable about these older texts to get the reference. This literary practice came about to differentiate the southern Chinese from their peers in the North living under "barbarian" rule, who would not understand the references and phrasings.

==== Developments in Buddhism ====
The southern dynasties also gave birth to distinctly Chinese schools of Buddhism adapted from the cultural sensibilities and developments in Chinese society, such as the Tiantai or Chan school (more familiar in the west under the name Zen). The developments of Buddhism became vital in the later reunification of China under one dynasty in the 6th century.

=== End of the period of division ===
This division of China lasted for close to 300 years. By the latter part of the 6th century, the conditions that created this division had begun to change. In the North, the period of migrations had ended and a long era of cultural accommodation had ensued. In the South meanwhile, the adoption of Buddhism and a process of familiarisation with the populations in North China began to create the ground for reunification into one China, especially in the Chinese elite.<ref name=":010">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 11: Sui Reunification and the Rise of the Tang|publisher=The Teaching Company}}</ref>

== The Sui dynasty ==
In the 580s, circumstances arose that brought this long period of division to an end. A general named Yang Jian, who came from a Sino-turkic family in the northwest of China, seized power for himself in the state he served in, called the Northern Zhou dynasty. He founded his own dynasty after a coup, which he called the Sui dynasty -- named after his home district.<ref name=":010" />

Such violent overthrows were not particularly uncommon in this period of division, but what made the Sui dynasty historically important was that by 589, Yang had re-established a single unified empire encompassing both North and South China.

Part of his success was due to him being a general, leading troops in campaigns and conquering the rest of North China. At the same time, he did not employ this method in South China and one of his first acts was to send his son, Yang Guang, to be viceroy of the city of Yangzhou, a very important economic and political center in East China. The city was technically in North China (and under Sui control), but sat right on the border with South China, close to [[Nanjing]]. From there, Yang Guang was able to get into correspondance and negotiations to peacefully reconcile and integrate South China.

They also used Buddhism as a common cultural trait between the North and the South to reach out to their neighbours. They eventually negotiated a marriage between Yang Guang and a princess in the South to reintegrate that state, with other Southern states soon following suit.
[[File:China-sui-large.png|thumb|Sui dynasty borders laid on top of modern day China map (PRC)]]

=== Establishment of the Sui state ===
While the Sui dynasty itself did not last very long and only had two emperors (Yang Jian and then Yang Guang), it did succeed in establishing a new political order which the Tang inherited after them, and which proved to be long lasting.

==== Legal code ====
A legal code was formulated which gave a body of law to the empire as a whole, used to regulate the affairs of the government and citizens. The adoption of a legal code was not a new undertaking at this time in Chinese history, but their code brought together laws from North and South China and their several different administrations and states, creating a cohesive body of law for the many different cultures living in the now reunified China.

==== Well-field system ====
The Sui dynasty also used the well-field system (井田制度, ''jǐngtián zhìdù''), which was first attested to in Chinese early history (and even pre-history, going back to the mythological foundation of China). It was a way of distributing land based on a grid system: the outer fields in a given area were private fields owned and farmed by peasants, with the central field farmed for the lord or empire: the revenues from that field would be used to pay taxes and tribute. Dr Hammond notes that the character for well (井, ''jǐng'') was likely drawn after this system.<ref name=":010" /> 

The Sui did not bring back this exact system, but used it to promote a stable agricultural order. While all land in the empire theoretically belonged to the emperor, this system made sure that arable land was redistributed to different families every 3 years, ensuring that all families had about the same access to agricultural resources. This redistribution prevented the accumulation of large amounts of land in some families, avoiding the formation of both landlords and landless peasants.

The land was not all distributed equally; there were still aristocratic, land-owning families which were inherited into the Sui dynasty from the period of division. The well-field system did not expropriate this owned land; it was entirely exempted. Still, this system allowed farmers to fulfil their own needs.

==== Frontier defence ====
The Northwest frontier remained a zone of instability, and in order to defend it, the emperor established agricultural colonies: soldiers would be sent to the frontier and support themselves by farming the land there rather than being financed and fed by the heartland of China.

==== Public granaries ====
Finally, the Sui dynasty established a system of public granaries. Every year at harvest time, surplus grain was bought at subsidized prices and stored in granaries. During the course of the year as grain prices rose due to lower supply until the next harvest, the government would release grain into the markets from these granaries to maintain stable supplies and prices.

=== Succession of Yang Jian ===
Yang Jian was succeeded by his son Yang Guang, the second and last emperor of the Sui. His rule was marked by military expeditions, seeking to re-establish Chinese control on territories lost on the periphery during the division of the North and South. In particular, he launched some military campaigns against Korea. These campaigns were not successful and created dissatisfaction in the empire.

He also launched military campaigns to the northwest, into Central Asia, to try and push some of the Turkic populations away. These campaigns were also a financial drain on the economy and disrupted communities as soldiers were taken away from their villages to fight on the frontier.

At the same time, the Northwest of China had been slowly going through a slow, millennia-long process of climate change which progressively made the region warmer and dried, reducing agricultural production. By the Sui period, the Northwest was not able to support the lavish lifestyle of the imperial court (located since earlier times at Chan'an and Luoyang nearby). As such, grain was required to be imported from the South, for which Yang Guang undertook the construction of a canal (which he never finished but would later become the Grand Canal, which remains the main economic artery from North to South China). This project required a large mobilisation of both labour and resources and while necessary when looked at with historical insight, the construction of the canal was not popular with the masses.

=== End of the Sui dynasty ===
The Sui dynasty lasted from the years 589 to 617. The masses were not happy with the failed military campaigns and the construction of the Grand Canal that took their toll on their families and local economy. This discontent however, by itself, would not have been enough to dissolve the Sui dynasty. In addition to that, a story (or rumour) was going around the capital that the throne "was going to be occupied" by a person named Li (the ruler of Sui being named Yang).<ref name=":010" /> This story was first spread by travelling soothsayers and then made into a folk song. Yang began to mistrust government officials named Li and, to safeguard his rule, had them executed as well.

In the city of Tanyuan, Li Shimin, the son of a garrison commander, saw the writing on the wall for himself and his father: if they were going to wait around, then eventually the emperor would have them executed for being named Li. Yuan, Shimin's father, had to take the opportunity and seize power for himself. In 617, Li Yuan, his son and their troops marched south to the capital. Rebellions broke out, and the court collapsed fairly quickly: Yang Guang died, and authority disintegrated at the capital.

== The Tang dynasty ==

=== Establishment of the dynasty ===
A brief period of civil war ensued after the end of the Sui dynasty, with a number of contenders seeking to establish their dynasty. The Li family were the leading contenders and, in 621, all of their opponents were disposed of, leaving the way open to establish their Tang dynasty with Li Yuan as emperor. The name Tang, like many dynasties before them, was the name of the district Li Yuan originated from.<ref name=":010" /> The capital was established at the historical site of Chang'an, with the city of Luoyang being used as a secondary capital.

==== Emperor Li Shimin ====
Li Yuan abdicated in 626 to his son Li Shimin, who reigned for 23 years until 649. He continued many of the practices started by the Sui dynasty. Additionally, he formalised the number of ministries to just six which was kept by all subsequent emperor dynasties down to the year 1911, when the Imperial structure of China was overthrown and the Republic of China was born.<ref name=":011">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 12: The Early Tang Dynasty|publisher=The Teaching Company}}</ref>

He also created a separate bureaucratic institution to manage the affairs of the imperial household, creating a clear demarcation between the personal activities and finances of the royal family and the affairs and finances of the government. This demarcation was an important development because it removed the state a bit more from being the personal property of the emperor. It also proved to be a robust structure so as to prevent abuses by the royal family which had created problems in the past.

Finally, Li Shimin also extended Chinese power into Korea and what is now Vietnam. In the far west, Tang armies projected their power much further than any other dynasty before: they established direct Chinese control as far as Xinjiang province. Into what is now parts of Kazakhstan and Uzbekistan, protectorates were established with local rulers, contributing to the economic expansion of the Tang dynasty.

=== Economic and social change ===
[[File:Location of xi'an.png|thumb|Location of Xi'an city in China, previously the historical capital of Chang'an.]]

==== Chang'an capital ====
The city of Chan'an was important not only due to its historical role, but also because it was strategically placed at the beginning (or end) of the Silk Road when it came to the road's entrance into (and out of) China.

Trade routes from all over Asia converged at Chang'an, which made it develop into probably the greatest city in the world at that time: the city housed a population of 2 million people, established in a geographical area vastly larger than its biggest "rivals" at the time (Cairo and Baghdad). As a center of trade, people from civilisations all across Eurasia converged there, making the city into an unrivalled -- and probably unprecedented -- cosmopolitan multicultural center.<ref name=":011" />

==== Prosperity ====
The first century of Tang rule was otherwise marked by peace, China having been unified again, which allowed for prosperity which fuelled economic growth along with the vast international trading system.

Demographic growth followed; part of the population growth was due to the expansion at the borders, bringing in new territory, but also due to internal factors: no internal warfare meant more people survived, and the economic activity of the Silk Road raised the standards of living for the people and contributed to longer life expectancy.

It is estimated that during the course of the Tang dynasty, the population of China grew from ~120 million to ~250 million.

==== Social order ====
The social order in the Tang dynasty was a continuation of the aristocratic system which had emerged back during the Han. The basis of wealth and status was the ownership of large estates, concentrated into families who had been in possession of these estates for hundreds of years.

The Tang formalised and regulated these estates to an extent even greater than seen in previous dynasties. In the capital, a genealogical registry was made, maintaining a record of who was a member of which family. Officials in the government tended to be recruited from these families.

This basis for recruitment maintained the aristocratic order which pleased these families, but Dr. Hammond also notes that to function as an educated and literate government official, one needed a certain amount of economic resources to learn the textual tradition, the writings of Confucius, the histories of China, the body of precedent and historical knowledge necessary.<ref name=":011" /> A peasant family who needed to deploy all its available labour-power towards the production of food simply would not have been able to spare a young man for the several years needed to educate him on these topics.

=== Empress Wu Zetian ===

==== Biography ====
Li Shimin eventually died and passed down the title of emperor to his son. In 690, empress Wu Zetian assumed the throne, an unprecedented event in China: all emperors before her had been men. She was also the last empress of China.

At a very young age (perhaps around 12 or 13, she came into the court as a concubine during the last years of Li Shimin -- it is not clear that he actually met her. When the emperor died, the tradition was that all women and consorts at his court were retired into Buddhist temples so that the partner of an emperor could not become anyone else's partner.

On the first anniversary of Li Shimin's death, his son Li Zhi visited the former concubines and became captivated by Wu Zetian, who would have been around 15 years old at this time. He brought her back to the palace, making her his favourite consort. Eventually, he displaced his own wife and made Wu Zetian the empress, giving her direct proximity to the throne. At the same time, Li Zhi had no sons to inherit the throne but only nephews, making Wu Zetian the aunt of the next two emperors that followed. In 690, she set aside her nephew, who was still a very young boy, and assumed imperial power for herself.

Wu Zetian ruled for 15 years, and one of her first acts was to change the name of the dynasty to the Zhou dynasty, echoing back to the ancient dynasty. She stepped down in 705 from the throne, and her nephew, who had briefly reigned before her, returned to the throne. Wu Zetian died of natural causes shortly after.<ref name=":011" />

==== Impact ====
The reign of empress Wu Zetian was a very unique moment in Chinese history. In traditional Chinese historiography about her, her story is presented as a pretty bleak event; the Confucian scholars who wrote her stories down didn't like that a woman was on the throne and they did everything they could to smear her reputation. Looking at the records of her 15 years rule however shows that she was an average ruler, who didn't innovate much but also stayed the course in terms of stability.

She was noted for her patronage of Buddhism, and for undermining the aristocratic recruitment system established by Li Shimin. As the royal court distrusted her, she sought to create alliances with minor families by recruiting them at the royal court and garner support from them instead.

=== Emperor Xuanzong ===
After Wu Zetian's abdication, her nephew (known as Xuanzong, personal name Li Longji) took the throne, reigning until the year 756 -- over 50 years. He is considered one of the great emperors in Chinese history, not because of his own achievements, but because he ruled over the golden age of the Tang dynasty, a time during which the economy flourished, the role of Chang'an as a trade center continued to be significant, and Buddhist culture flourished and both temples were built and great translation projects were carried out to further embed Buddhism in Chinese culture.

The first part of the eight century was also an age when some of the greatest poets in all of Chinese history were contemporaries: they knew and wrote each other, and created a very rich and dynamic moment in Chinese arts. Figures like Li Bo, Du Fu, Meng Haoran from that period are names that any Chinese schoolchild today would be familiar with and learn about.<ref name=":011" />

==== Quest for immortality ====
Emperor Xuanzong was a competent emperor nonetheless but as he became older, he became more concerned with the inner life of the palace: notably the quest for immortality.

At the time in China, coming from the time of the Northern and Southern dynasties, a spiritual practice known as religious Daoism (differentiated from the philosophical practice) was particularly concerned with seeking out immortality, being in communication with a spiritual realm which was populated by immortal beings. Part of the way this was done was through taking various chemical substances into one's body, producing heightened states of spiritual sensitivity (likely hallucinogenics). The people involved in this practice believed that they came in contact with spiritual beings who passed onto them various "recipes" for better concoctions to pursue their spiritual quest. Xuanzong became involved in these activities as he grew older, perhaps unsurprisingly.

==== Yang Guifei ====
At the same time, emperor Xuanzong became enamored with a woman known as Yang Guifei -- from the earlier ruling Yang family deposed by the Li. Guifei was not her personal name, but a title meaning "precious concubine". She was selected by Xuanzong to become his favourite, and came to play a role in his life beyond that of a simple palace lady, becoming a partner and advisor in the affairs of state and other concerns. This made her a very powerful individual -- at least potentially -- so much so that Confucian officials at the court became jealous of her.<ref name=":011" />

=== An Lushan and Frontier security ===
One constant problem in the Tang dynasty was the security of the frontier in the west, maintaining the defences along to border with inner Asia. The Tang dynasty continued the military colonies from the Sui dynasty, but also came up with new policies. One of these was to employ military forces from one part of the frontier in the defence of another part of the frontier. The Uighur people for example, from the northwestern frontier, were sent to the defence of the northeastern frontier, where the people they were defending against had nothing in common with them.

One Uighur individual employed in this capacity, known as An Lushan (likely Rakshan in his original language), was in charge of a Chinese garrison near where the modern city of Beijing is located. He was a very competent general and defended his part of the frontier effectively. This made him into a popular figure at Xuanzong's court. Every so often, these commanders would come to make a report to the capital and historical records show that when An Lushan came to the capital, he was received quite lavishly by the emperor himself. 

Through these visits, An Lushan also became a good friend of Yang Guifei. Their relationship is recorded as being perfectly ordinary but jealous officials at the court chose to slander both Yang Guifei and An Lushan by claiming they were having an illicit affair. The emperor didn't believe in the rumours, but he was so persistently fed these rumours that eventually, he began having doubts. He summoned An Lushan to the capital. An Lushan was not unaware of the rumours, and so he refused to make the trip. This was taken as an act of guilt on the part of An Lushan, and so the emperor summoned him again, and An Lushan agreed to come to the capital.

==== The An Lushan rebellion ====
An Lushan took his army with him to see the emperor. This triggered, in the year 755, the An Lushan Rebellion, which lasted until 763 and shook the Tang dynasty to its very core, as their rule up until then had been one of great successes and internal peace.

A number of battles and sieges took place, and he emerged victorious in every case, his armies growing each time. As he approached the capital, the emperor and courtiers decided to run away (despite having summoned him officially). They fled to the southwest into Sichuan and the capital of Chang'an was captured by the rebels. During this march, the emperor realized that he could not continue his relationship with Yang Guifei, and he allowed his courtiers to assassinate her.

==== End of the rebellion ====
The rebellion eventually subsided after both the emperor and An Lushan died (the first of old age, and the latter during the course of the rebellion), and both of their sons continued the hostilities in their fathers' stead.

With the capital lost, the royal family had to find new avenues of support against the rebels, the main method by which they made compromises with powerful military officials who were stationed far away from any hostilities. When approached by the emperor, these generals saw an opportunity to negotiate with the emperor and obtained concessions. For example, the court had to agree to relinquish the control of certain taxes, to be owned by the generals instead.

=== Aftermath and impact of the An Lushan rebellion ===
These deals were successful as they allowed the Li family to preserve its rule and defeat the rebellion. However, in granting these concessions, the dynasty weakened itself irreparably. After the An Lushan rebellion ended in 763, the Tang dynasty was never able to regain the dynamism and prosperity that they had previously enjoyed.

Soon, the same situation that had led to the demise of several earlier dynasties resurfaced: the Tang court directly controlled the areas around Chang'an and Luoyang, as well as certain areas (particularly in northwest China) that were traditionally under the administration of the ruling dynasty. But otherwise, large portions of the empire -- although they continued to recognize the authority of the ruling family and continued to send tribute, kept bigger proportions for themselves and became increasingly autonomous.<ref name=":012">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 13: Han Yu and the Late Tang|publisher=The Teaching Company}}</ref>

At the same time, many noble families began to find legal mechanisms to grant their land to Buddhist monasteries, making their land tax exempt. The contract worked by giving ownership of the land to the monastery, with the family retaining rights to some of the use of the land, for example owning some of the harvest. With this mechanism, the family would ultimately make more profits from not paying taxes on the land, even if they only retained part of the harvest and could not use their land freely any more.

The confluence of these two phenomena led to a major loss of revenue for the royal family, who especially needed money after the several years of civil war. This led the government to increase the rate of taxations, mostly impacting smaller peasant families who didn't have much to their name in the first place. This not only caused unrest, but also increased wealth inequality.<ref name=":012" />

== Late Tang dynasty ==

=== Confucian revival of the 9th century ===
At the beginning of the 9th century, a movement to revive the centrality of Confucianism in Chinese political culture and operations of the state started to appear, the biggest of which was the Gu Wen (''old-style prose'') movement, a literary movement led by Han Yu.

==== Han Yu ====
Like several of the Gu Wen advocates, he was a new kind of figure in the Tang imperial government. Coming from a minor aristocratic family, he entered imperial service by taking one of the occasionally-held imperial examinations, demonstrating literary accomplishment as opposed to simply being born in privilege.

He critiqued the problems that were plaguing China at the time through literary culture. As a member of the scholar elite, he considered that the centrality of literary culture was fundamental to the functioning of politics (the Confucian ''shi''). To Han Yu, prose writing should be as clear and simple as possible, communicating the author's ideas clearly. He criticized the flowery prose that came about in the Southern dynasties, saying it was a kind of writing in which people were more concerned about ''how'' they were saying something rather than ''what'' they were saying.

He blamed this development on two influences: Buddhism, and religious Daoism (a response from within Chinese culture to the arrival of Buddhism). He considered that both were bad influences on Chinese civilization largely because they represented the rejection of the family as Confucius envisioned society. Buddhism especially directly challenged the worship of the ancestors that had been central to Chinese spirituality since ancient times. Han Yu argued that with Buddhist monks not having children and thus not continuing their family line, there were no descendants to carry out offerings to the ancestors who would be abandoned.

He advocated a return to the values of Confucianism in essays, two of his most famous ones being titled ''The origins of the Dao'' and ''The memorial on the bone of the Buddha.<ref name=":012" />''

===== ''Memorial on the bone of the Buddha'' =====
In ''Memorial'', he took on a major event that happened in his time: a bone of the Buddha's finger was brought to Chang'an, attracting many pilgrims with it. The emperor himself had announced that he would go to the monastery and pay his respects to this relic. Han Yu wrote a letter to the emperor saying (in a very straightforward Confucian manner) this was not appropriate for the emperor of China to do, "paying respect to the rotten corpse of a foreigner" -- underlying that not only was it problematic for the emperor to give meaning to a body part (bodies, and the people taking care of them, being on the fringes of society in ancient Chinese culture), but moreover that the Buddha was a foreigner, which was scandalous to Han Yu.

The emperor was not pleased by Han Yu's letter, and sentenced him to exile in the fringe parts of South China, near the border with what is now Vietnam. This punishment happened several times in the course of Han Yu's career, owing to this direct approach to matters of policy, and was often a death sentence as malaria or other tropical diseases would contaminate the exiled.<ref name=":012" />

===== Legacy =====
Han Yu died in 824. While he and the other Gu Wen theorists never achieved enough influence to sweep over the entire nation, they created an intellectual position which became part of the ongoing discourse on Chinese culture. The values that Han Yu advocated for would later be picked up again in the 11th century.

Han Yu himself did not talk about financial questions; he attacked Buddhism on moral grounds of it being foreign, undermining the family, Confucian values and Chinese culture.

=== Final decades of the Tang dynasty ===

==== Purge of Buddhism ====
In 845, 20 years after Han Yu's death, a great purge of Buddhism took place -- mainly as a response to Han Yu's criticism as well as the fiscal problems facing the dynasty. Emperor Wuzong, a fanatical Daoist, issued edicts to ban Buddhism and established monasteries from China. This created a great rupture in Buddhist monasteries: monks and nuns were told to return to their families, and their monasteries torn down.

More importantly, monastic lands were also confiscated and turned over to the royal family, which allowed for a new stage of land redistribution, giving it back to small farmers which the court could tax. In effect, over several decades privately-owned aristocratic lands (originally handed to monasteries to avoid taxes) were seized by the government who could now tax this land even more.

The purge of Buddhism lasted only 6-7 years, by the early 850s, Buddhist monasteries were able to be re-established and quickly reappeared in China. However, they did not have their land restored; without these land holdings to support themselves, monasteries were unable to reacquire the large population base that they had before.

While this return of tax revenue helped the government, it did not support the dynasty for very long.

==== End of the Tang dynasty ====
All of these conditions eventually culminated into a crisis. Civil wars broke out around China with powerful generals trying to wrestle territories from their peers. In the last years of the 9th century, military forces penetrated into the imperial palace and massacred the eunuchs, making the final emperors of the Tang into puppets of military warlords.<ref name=":020">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 14: Five Dynasties and the Song Founding|publisher=The Teaching Company}}</ref>

This process ended in the year 907 when the last claimant to the throne of the Tang was deposed and murdered, which led the dynasty to completely disappearing.

==Five dynasties period==
Following the dismantling of the Li dynasty, China was again fragmented into several different kingdoms. This period, however, was comparatively brief; lasting only 53 years. It would also be the last time China broke down into a multiplicity of small states.<ref name=":020" />

While this period is known in Chinese historiography as the Five dynasties period, there were actually up to 20 different states that existed in total during this period, not all at the same time. The five dynasties that gave the name to the period are those which were considered (by later historians) to have passed along the legitimate transmission of authority (''Zhengtong''), tracing a line from the Tang through these five consecutive dynasties and into the Song. The longest of those five dynasties lived for a total of 13 years while some of them survived only for a year or two.

This period was one of great instability and constant warfare. Military power, much like earlier periods, was the main component for assuming authority: anyone with enough troops and resources could establish their regime.

== Song dynasty founding ==
In 960, the Five dynasties period officially came to an end. A pair of brothers, Zhao Guangyin and Zhao Guanyi, seized power in the last of the five dynasties state. They overthrew the young king and proclaimed their own dynasty, the Song -- named after their place of origin.

The Song, which was established in 960, proved to be the state that reunified China after this period and would last down to the year 1279.

The two brothers succeeded one after the other on the throne for a total of 35 years, but their two reigns are sometimes counted as just one. They were military commanders who had come to the throne by military means, and thus faced a very urgent problem: anybody else with means and resources could challenge their rule and seize power from them in turn.

To avoid this fate, they carried out military campaigns to reunify China. By the end of the decade, they had militarily re-established an empire -- though smaller than the Tang empire even at its largest, not venturing as far into the frontiers.

=== New administrative order ===
To secure these new land acquisitions, the Zhao brothers established a civilian bureaucratic government which had been the norm since the Han dynasty; the mechanism to fill this government was to turn to the aristocracy and wealthy families who could afford to educate and spare their sons for government service.

Following the civil war and dissolution of the Tang however, almost all of these aristocratic families had simply vanished and died off. Their land titles had been seized and burned during rebellions, and the family members would be executed by peasant rebels when they marched on the estates. Noble families would also serve as generals at war, of which there was plenty during the late Tang, and died there. When administrative centers were fought over and captured, the conqueror would often burn documents.

Essentially, the Zhao brothers did not have this aristocratic and educated base from which they could recruit. To solve this problem, they looked towards the past and found the imperial examinations that had been started in the early Han dynasty, albeit as a minor mechanism for recruitment. While this system did not become the sole means of recruitment, it was expanded and became a central institution of the Song dynasty. The other two main means of recruitment were by recommandation from someone in the administration, and through the ''Yin'' (shadow) privilege. Officials could extend the shadow privilege to their sons who did not have to go through any other qualifying procedures. 

Still, the examinations remained the main avenue for recruitment; looking at the highest-ranked members of the Song administration (who made policies) reveals that the great majority of them were people who came in by the imperial examinations.<ref name=":020" />

==== Undertaking of the imperial examinations ====
While legally speaking, almost anyone could take the imperial examination, some groups were excluded by default, the biggest of which being women. Merchants, who were the second most significant group in terms of numbers, were also banned from taking the examination through generations (their sons and other descendants were automatically ineligible). This had to do with the Confucian system which considered merchants to have very low social utility as they didn't produce anything themselves.

While this left around 50% of the population technically eligible for the exams, one needed to be educated in order to even show up at the exam, which were out of reach for many families who could not spare the labour-power and finances required to educate their son.

The examination process itself took inspiration from the Confucian revival seen under Han Yu. The exams tested the candidate's mastery of a body of Confucian writing, historical texts and classical literature. The candidate needed to be able to cite texts from memory and apply them to questions of government or administration. They also needed to be able to compose poetry, writing in an elegant literary style.

==== Cultural changes of the imperial examination system ====
This central place the imperial examinations took in the material base of the country influenced its superstructure heavily, and it became an institution of Chinese culture that survived for the next thousand years: preparing for the exams, taking the exams, being part of this system is what gave a sense of self and community to the elite. Whereas the old aristocratic families received their identity from being great families listed in the registry, the new elite families from the Song dynasty onwards however, people attained this prestige and status by participating in the imperial examination system, making them the educated ''shi'' of older times. This is also around the time the term ''shi'' came to mean not solely an advisor, but an educated person or a scholar as well.

Members of this strata knew each other from their participation in a shared literate culture, extending to people even who did not pass the exams; these were very tough to pass, held at two levels: local and national (and later provincial level). The pass rate at each level was only about 10%, with a fewer proportion of people attending exams at each higher level. On average, 100 people passed the exam every year. Those who failed their exam were still educated however, and came to constitute the scholar class.<ref name=":020" />

==Intellectual ferment in the Song dynasty==

=== Place of the shi in society ===
The importance of the imperial examination system as an institution of imperial China from the Song dynasty forward led to a major cultural crisis in the Chinese educated elite, who went through a process of self-realized and realized what exactly their role was and what they should do with the power they possessed, being not only educated and literate but also in the government administration.<ref name=":020" />

The ''shi'' in the Song dynasty came to the conclusion that by having passed the imperial examinations (or even having attended them) and being educated individuals, they had access and were part of a system of governance and social leadership which they took as a very deep responsibility. Their official positions also afforded them some privileges; for example, they were exempt from labour duties in which a subject had to render to his liege at some time during the year. They were also exempt from corporal punishment.

Even those who only attended the examinations but didn't pass could find a role in public and social life, serving as teachers for example, and Dr. Hammond notes that many private academies flourished during this period.<ref name=":013">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 15: Intellectual Ferment in the 11th Century|publisher=The Teaching Company}}</ref> They could also become tutors or clerks and secretaries in government. Still, this social class remained a very small portion of Chinese society, amounting to 5-6% of the total population at most.

=== Three basic positions ===
From the writings and other documents that survived the Song dynasty, historians are able to define three distincts positions, though Dr. Hammond notes they are not formal enough to be considered schools of thought.

==== Wen ren and Jing shi ====
Two similar groups of scholars came to emerge during this period, who had 

The first group were the ''Wen ren. Wen'' translates in this context as "literary culture"; it has to do with things that are written or produced with writing tools (such as painting or calligraphy). Language, poetry, prose writing, the classics, etc. fall under the general rubric of ''Wen''. ''Ren'' means person or people, so ''Wen Ren'' in English translates as "literary gentleman".

The second group was also very concerned with literary culture but approached it in a somewhat different way. They were called the ''Jing shi'', meaning "ordering the world" or "statecraft"; they were focused on the application of the literary body towards the management of state affairs and government.

Both shared a faith in the literary textual tradition as a repository of knowledge and values, which were very important to these Confucian scholars.

===== Ouyang Xiu and Su Shi =====
Important individuals in the ''Wen ren'' group were ''Ouyang Xiu'' and ''Su Shi''. While Ouyang was a generation older than Su, they both knew each other and were good acquaintances. They came to know each other when Ouyang was the chief examiner in the year 1059, the same year Su passed his examination at the top of his promotion. Ouyang used his role as an examiner to promote his particular views, drawing upon Han Yu from the Tang dynasty; he was a practitioner of the ''Gu Wen'' principles, and gave preference to prospective examinees who wrote in the ''Gu Wen'' tradition of a clear, concise, to-the-point style. Su Shi was one of those and ranked in large part because of the style of his writing. From there, they looked at the literary heritage as a source of inspiration, knowledge and information, but also as a reservoir of good examples to follow in terms of values and qualities to live by.

There were still differences between the two acquaintances; Ouyang Xiu was an antiquarian, very interested in the past, collecting antiquities. He saw the literary past as a repository to inspire him. Su Shi, while having the same kind of immersion and familiarity with the past, aimed to achieve such a complete assimilation of that material that he could then spontaneously good writing. But in order to achieve that spontaneity, it was necessary for him to immerse oneself into the models of the past so as to absorb the values and manifest these good qualities.

===== Sima Guang and Wang Anshi =====
The Jing Shi thinkers shared concerns for the records of the past with the ''Wen ren'', but had a more practical bent to this body of texts. They were concerned with how one could draw from the literature of the past, its examples and values, to solve the problems of society in their day.

Sima Guang and Wang Anshi knew each other (as well as Ouyang Xiu and Su Shi); hey all lived in the same cities, went to the same social events, knew each other at court and were part of a shared cultural milieu.

In the late 1060s, Wang Anshi rose to the top of the imperial administration, being named chief minister of the imperial government. He was then given the authority by the emperor to launch a major reform program which he undertook based upon his personal interpretation of the history of the past. These were called the new policies, setting out to foster a more proactive state that will intervene in society to benefit the people. These policies involved, for example, the creation of state-sponsored schools to make education more widespread and a system of regulated agricultural loans so farmers would not be dependent on loans from aristocratic (landlord) families.

Sima Guang is considered to be the other greatest statecraft thinker of this period, but he was rabidly hostile to the ideas of Wang Anshi, showing that while they drew from the literary body of Chinese history to inform their views, they did not come to the same conclusions at all. When Wang Anshi was named as chief minister, Sima Guang resigned government and retired from the capital at Kaifeng, moving west to the ancient capital of Luoyang. In the 1070s, after Wang Anshi was dismissed from his positions, Sima Guang was brought back and set out to dismantle the policies of Wang Anshi.

His opposition to Wang Anshi's ideas was based upon a different interpretation of the values to be derived from the literary record of China: while Wang Anshi called for intervention to bring about a Confucian order, Sima Guang argued that the state should keep its hands out of society, and that the emperor should rely upon those within society with a "natural role" as leaders to address the problems their communities face. One way to interpret Sima Guang's views is to see him as defending the leading role and autonomy of the ''shi''; the ''shi'' being extracted from the wealthy land-owning class, i.e. those with privilege.<ref name=":013" />

==== Cosmological thought ====
At the same time, a third position grew in the ''shi''; a group concerned with linking human affairs to larger cosmic orders and natural systems. In the Northern Song, some thinkers began to place emphasis on a concept very different from ''Wen'', which they called ''Li''. While ''Wen'' refers to things literary or the "pattern" formed by words on a page, which by definition are man-made. ''Li'' on the other hand refers to patterns that occur in nature, the word coming from the striped patterns that appear on some types of rocks. The word ''Li'' itself means pattern or principle. 

This distinction was fundamental to the cosmological thinkers, who were concerned with trying to understand the naturally-occurring patterns of the world around them. They saw moral values as coming not out of ''Wen'' but being derived directly from natural patterns, because they were embued with normative values. That is to say, patterns that can be observed in nature do not inform simply the way things ''are'', but the way things ''should be'' -- giving them a moral value. In some ways, this calls back to the Confucian ideal of the ''Dao'' ("way"), being the proper order of things which is inherently desirable.

In the ''Li'' cosmology, acting in accordance to those patterns makes one's actions morally good, while acting against the patterns or principles make one's actions bad. Initially, the cosmological thinkers didn't reject ''Wen'' but argued that it was a mediated experience; relying on the writings of the past was to rely on a humanly constructed understanding of the world. While there were insights to be gained there, they argued, it was not the same as directly apprehending the patterns and principles of the universe.

=== Legacy ===
While in the Song dynasty these factions and their ideas were only germinal, the period that ensued from this cultural crisis is almost the richest period in Chinese intellectual history and the development of traditional Chinese thought since the Warring states period.<ref name=":013" /> It is seen as a critical point in Chinese history as later Chinese thinkers would work from the foundations that were laid in the Song dynasty in regards to their theoretical writings or arguments.

==Conquest states in the North==
The Song dynasty's borders, while larger in some areas than their predecessors the Tang, did not extend to the borders of modern day China (the People's Republic). Outside of these borders were, at different times, large empires existing which were sometimes in conflict with China.<ref name=":015">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 17: Conquest States in the North|publisher=The Teaching Company}}</ref>

Two of these states came to cause trouble for China, both coming from the North (Northeast and Northwest respectively).

=== Northeast state of Liao ===
The Northeast of China, which we call Manchuria in modern times, is geographically very different from the Chinese heartland (North and South China): by contrast to the more marginal areas of the empire (such as the tall Tibetan plateau or the arid Xinjiang desert), the north-east was very lush and well-watered, making fishing, hunting and harvesting natural products fairly easy to live in for semi-nomadic populations, inhabited by the Khitan and Jurchen people since ancient times.

When the Tang dynasty disappeared in 907 and China fragmented in the period of the five dynasties, a leader of the Khitan people (named Abao Ji in Chinese historiography) seized power in the north-east and proclaimed a state which he called a dynasty, emulated after the Chinese model. The Khitan would have been very familiar with China and the Tang who exercised influence over many of the Khitan people, such that their disappearance had a very direct impact on the Khitan. In this context, Abao Ji replaced the authority that China had relinquished.

Over the next 20 years, Abao Ji conducted military campaigns to extend and consolidate his power. He broke from traditional Khitan modes of leadership -- as a semi-nomadic people, the Khitan had not had a highly organised and centralized political system prior to Abao Ji; traditionally, the elders and more prominent warriors within particular families would emerge as tribal leaders and individuals would be selected as leaders during times of war or hunts. Instead, Abao Ji effectively set himself up as an emperor.

The adoption of a dynastic title, and calling his regime the Liao dynasty, was a reflection of this change; but it did not come without strife from the Khitan people. The military campaigns he waged served the purposes not only of consolidating territory, but also of seizing loot which Abao Ji would redistribute to the tribal families so as to gain their loyalty.
[[File:Sixteen Prefectures map.png|thumb|Map showing the location of the 16 prefectures]]
Critical in this process was the ability of the Khitan to seize a strip of farmland at the very northern edge of China which came to be known as the 16 prefectures that had been part of the Tang. This area was very different from the rest of Liao territory: instead of sparsely-populated forests and mountains, this territory was not only a fertile farmland, but also very densely populated by Chinese people. By controlling this thin area, the Khitan brought a considerable amount of wealth to the Liao state.<ref name=":015" />

==== War against the Song ====
When the Song dynasty arose after 960, they aimed to regain this lost territory controlled by a non-Chinese ruler. In the year 1004 and again in the year 1044, major military campaigns were launched against the Khitan to try and seize the 16 prefectures. Both of these campaigns were however unsuccessful. This resulted in humiliating moments for the Song dynasty, and the Song were forced to sign treaties with the Liao; this was quite a change for the Chinese empire who, as a major power in the region, had previously never signed agreements with another power. What they ended up agreeing to was to pay annual tribute to the emperors of the Liao dynasty, in gold and precious cloth (such as silk). These subsidies were doubled after the second unsuccessful campaign of 1044.

After the second failure, the Song decided that military reconquest was not a cost-effective method of regaining this territory and stopped launching more campaigns. For the Khitan, these tributes are a very significant source of income. For the Chinese, while not being a large economic drain, the tributes were a very humiliating situation however.

As time went by, the Liao dynasty evolved in various ways. The Chinese population inside the Liao state made up 70% of the total population, and as such the Khitan developed a system of dual administration: in the 16 prefectures, which was populated by their Chinese population, they used the Chinese bureaucratic system that was already in place before the Khitan arrived. This was very effective for the purposes the Liao desired, which was to extract wealth from these lands and keeping the people living there away from rebellion. In the rest of the Liao state, they retained traditional Khitan ways -- at least most of the time; a process took place over long periods of time by which the Liao court became more like the Chinese bureaucracy they had sought to emulate as the Khitan rulers get used to living a Chinese imperial lifestyle.

This eventually alienated Liao emperors from traditional Khitan customs, resulting in tensions within the Khitan people. The Khitan emperors would also reward their followers by often granting them bits of land from the 16 prefectures. As they granted these lands however, they often became tax-exempt and took away a major source of revenue for the Liao state. The tributes coming in from China were helpful, but not sufficient to offset this loss.

Eventually, late in the 11th century, the Liao state had trouble paying its military forces. Unrest was beginning to spread among the Chinese population, and insurrections began to take place against Khitan rule. In parallel, the Chinese had devised a strategy to retake the 16 prefectures: they found another non-Chinese people, the Jurchen, who could open a front with the Khitan that would divert them from defending the 16 prefectures.<ref name=":015" />

==== Jurchen meddling ====
The Jurchen lived further north than the Khitan and some had been incorporated in the Liao state. China used this situation to incite the "free" Jurchen, living outside of Liao territory, to invade the Liao state by sending gifts and advisors. In particular, they encouraged a Jurchen ruler named Aguda to defy the Liao emperor. In the 1120s, the Jurchen launched military campaigns against the Khitan. By this time, the internal problems of the Khitan had developed to the point that they could hardly mount a defense against the Jurchen. To further weaken the Liao state, China also cut their tributes.

In several years, the Jurchen managed to invade and destroy the Liao dynasty. However, while China had expected to have a docile neighbour who had taken care of their problem for them, they actually had a rude awakening: after the Jurchen had been trained, organised and successfully destroyed the Liao state, they continued their campaigns down into China and in the latter part of the 1120s, they had seized much of Northern China -- notably capturing the northern Song capital at Kaifeng along with the emperor himself and his mother. They were carried off to the north in captivity and were never ransomed, instead living the rest of their life there while another emperor was put on the throne.

After the capture of Kaifeng, the Chinese court fled south, which instigated a period of several years where  the Jurchen armies were effectively chasing the Chinese court from one place to another.

Finally, the Song forces were able to regroup and mobilize forces and push back against the Jurchen, ultimately being unable to drive them all out of China. By the early 1130s, a clear line of demarcation between Chinese and Jurchen-controlled territories had emerged, located about midway between the Yellow river and the Yangtze river.

This marked the beginning of the Southern Song for China, the second half of the Song dynasty. Their new capital was established at the city of Hangzhou, located on the southern coast of China.<ref name=":015" />

=== Jin dynasty ===
Meanwhile, the Jurchen had set up their own dynasty, which they called the Jin (meaning gold in Chinese, taken in reference to the most prominent "golden clan" in Jurchen culture). They too developed a dual system like the Liao dynasty, with their Chinese population representing over 90% of the total population in Jurchen territory.

The Jin dynasty accommodated to Chinese culture much faster than the Turkic invaders of the North and South period did; within a generation or two, the Jin had effectively become a Chinese state as many of the Jurchen people in the north moved into Chinese land and adopted Chinese lifestyle, settling down and acquiring land. The Jurchen dimension of the Jin state diminished greatly, though it did not disappear entirely.

The Jin state retained a lot of the features that had been in place during the Northern Song in terms of art, poetry, intellectual debates (such as the Wen and Li factions), etc. In this way, the Jin state is considered to be essentially a continuation of the Northern Song. The economic system of the Jin also remained the same as it was before, due to the North China plain being traditionally the breadbasket of China and retaining their agricultural economy.<ref name=":015" />

== Southern Song dynasty ==
The reunification of China remained very important in the Southern Song, though no serious efforts were made after a Chinese general was betrayed during the war and lost the empire's last chance to challenge the Jurchen.<ref name=":015" />

The capital at Hangzhou was considered a temporary capital, with the permanent and "real" one being at Kaifeng, showing how much the Chinese intended to reconquer the North. However, the Song dynasty ended up never achieving that goal as a little over a hundred years later, the Mongols conquered China and established their own empire there.

=== Geographic nature and demographics ===
By the geographical nature of the terrain the Southern Song had come to possess (located in Southern China), their economic base had radically altered from the time they had possessed a whole, unified China. As seen previously, the north of China consisted of mostly agricultural (and indeed high-yielding) plains, forming the breadbasket of China in history. By contrast, the southern parts were hilly, with centres of population being separated by difficult to parse hills, river valleys and low mountains.<ref name=":016">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 18: Economy and Society in Southern Song|publisher=The Teaching Company}}</ref>

The population of the Southern Song amounted to 60% of the total population of Chinese people. Beginning in the Tang, there had been a shift in the region populations gravitated towards. Back in the Han and earlier times, the great majority of Chinese people lived in the North or to the West. As China expanded geographically, people migrated to the South which resulted in a greater dispersal of people. By the end of the Tang dynasty, the majority of Chinese had come to live in the South. This trend reversed by the end of the Southern Song and today, there is about a 50/50 distribution between North and South China.

=== Cultural identity ===
Because of the "remoteness" imposed by the geographical nature of the hilly terrain in south China, localities seemed to develop a greater sense of identity from each other, a conscious thought that their settlement existed and was different from another settlement.

Because of this particularity, this transformation of the Song from controlling all of China to just the southern half had some effects on the ''shi'' class of educated political officials. In the Southern Song, they changed the ways they arranged marriages in a very clear (historically) marker. In the Northern Song, the political capital at Kaifeng had been a great cultural center; officials from all around the country travelled there every three years for assignment to new duties. Through these travels to the capital, families would meet each other and negotiate marriages. Kaifeng had become a major center for such arrangements, and it wasn't rare for people from opposite ends of the country to meet and arrange marriages between their families.

In the Southern Song, the wide horizon of arranged marriages scaled back dramatically. Marriages were not negotiated empire-wide as they had been before, but most families at this level tended to keep marriages within a narrow local circle; perhaps a handful of townships at most. However, the tradition of travelling to the capital for re-assignment was kept from the Northern Song and these officials still took care of empire-wide tasks. This change in behaviour indicated a change in their thinking and cultural identity which was informed by the new material conditions they had found themselves in: the educated elite families in the Southern Song thought of themselves principally as members of local societies who served on a national level, rather than members of a national elite that served on a local basis.

These families also became much more involved in local affairs. They undertook public works such as repairing roads, digging canals, organising local militias to control bandits, even starting schools and academies. While nowadays we expect these tasks to be carried out by the government, this development marked the first time the Chinese government effectively started taking care of these issues. However, the management of these public works projects can only be called semi-governmental as they were carried out by local families ''besides'' of their imperial duties, not as part of them.<ref name=":016" />

=== Economy in the Southern Song ===

==== Local specialization ====
All of these factors led to differences in the economic base of the Southern Song. Notably, there came to be a trend towards local economic specialization -- the production of certain commodities became the specialty of certain locations. For example, tea had been grown more or less everywhere alongside grain and other crops. Under the Southern Song, tea came to be mostly grown in Zhiejang and Hunan provinces who abandoned other crops (including grain, which was a staple of subsistence farming) to focus on tea. Grain thus required to be imported, and long-distance systems developed to supply the regions with food.

The city of Jingdezhen became a great center of ceramics. Ceramics had been produced in China for millennia and many centers had developed. Jingdezhen however industrialized production; the imperial kilns were located there, and production was organized on a basis similar to assembly lines. Thousands of workers were employed, with teams running the kilns 24 hours a day. Distribution was also handled industrially: warehouses were built for storage, and then shipped not only all over China, but also made their way regularly as far as the Persian Gulf. From there, they could be shipped all over the world; Jingdezhen wares have been found as far as the Western coast of Africa and Mediterranean countries, making them a truly global commodity -- all regulated by the imperial state.<ref name=":016" />

==== Monetary policies ====
The imperial state, while continuing to be a Confucian government, put in place a number of policies which actively encouraged the growth of the commercial economy (trading) -- particularly though monetary policies.

The state encouraged and carried out a great expansion in the money supply which, at the time, was backed by precious metals. These policies had an international dimension as well; Song coins were allowed to leave the country and spread throughout East Asia, becoming the common currency in Japan and Korea at this time.

==== Paper money ====
The Southern Song also experimented with paper money, which was a fairly radical development. The Chinese recognized the use of money as a universal means of circulation or universal commodity, recognizing that it did not have to be a precious metal so long as it was accepted as having value by the people who used it. While not much paper money left the borders, it did circulate quite widely within China. The experiment didn't work out as well as intended however, and paper money fell out of use after the Song dynasty.

==== Growth of the merchants and artisans ====
These factors fostered the growth of a new class, merchans and artisans which derived their wealth not from agriculture or landlording, but from the production of goods and subsequent distribution and sale.

This started to apply some stress to Chinese society. In classic Confucian thought, merchants were at the bottom of the social strata, considered to be morally tainted (although they were recognized to have some social utility). Up until the Southern Song, the limited presence of merchants did not create a big problem for the state due to how they were perceived. However, as commercial activity expanded wideld, so did not only the numbers of merchants but the wealth they concentrated in their hands as well. Towns grew, where large numbers of merchant families made their home. They built elaborate mansions, wore fine clothes (often the same kind the educated elite would be wearing), had themselves carried around in chairs by servants, and eventually started emulating the culture of the elite: they bought books and paintings, they established libraries, funded public works projects, sponsored monasteries, etc.

This created tensions between the emerging commercial class and the established feudal elite who made their money on agricultural production; a situation highly reminiscent of the rise of the [[bourgeoisie]] in Europe and their later struggles against the established [[Feudalism|feudal]] order (even happening around the same time in history).

In China, this development took a different trajectory; the contradiction between the two classes was able to be diffused to some extent. This can be explained by the convergence of interests that happened early in the Song dynasty: wealthy landowing families started to take some of the wealth they were earning from their agricultural revenue and invested it in commercial enterprises, making there commercial partners. At the same time, merchants who were becoming wealthy wanted to reinvent themselves as these educated, elite families and bought land to set up their estates. After a generation or two, they would train their sons to take the imperial examinations to cement their ''shi'' status.

== Neo-Confucianism in the Song dynasty ==
As the material base in the (Southern) Song changed, so did the character of its ideas. It is during the Song dynasty that Neo-Confucianism  (''dào xué,'' 道学, "the learning of the Way")  emerged, theorized by Zhu Xi (1130-1200). He took after the cosmological thinkers of the past, notably those from the earlier Song dynasty, bringing all of their theories and methodologies in a coherent body of philosophy.

It should be noted that neo-Confucianism is a misnomer of sorts. While this is how ''dào xué i''s customarily called in the West and in English, it is not the name used in China. The distinction is significant because in traditional Chinese culture, one does not want to invent something "new" or "neo", but rather one wants to return to the correct interpretation of the past. ''Dào xué,'' while being "new" in the sense that it was developed as a coherent body of philosophy in the Southern Song dynasty millenia after Confucius, was not emphasized by Zhu Xi as being new, but as returning to the correct interpretation of the classics.

The core of Zhu Xi's argument is that there had been a shift in the source of moral values, from the primacy of the literay cultural tradition (the ''Wen'') to a primacy of the direct understanding or apprehension of the natural patterns and principles of the universe (the ''Li''). He believed that by observing natural patterns and deriving principles from them, one could ground morality in a very firm basis -- not being solely a matter of convention or what people had decided amongst themselves, but a natural order more powerful than humans.

Further, he argued that this was exactly what the sage emperors of Antiquity did -- emperors like Yao and Shun, who had harmonized themselves with the patterns and principles they'd seen around them, and thus why they were sages.<ref name=":017">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 19: Zhu Xi and Neo-Confucianism|publisher=The Teaching Company}}</ref>

Therefore, to Zhu Xi, the ''Wen'' was useful as a record of how people had understood those insights of the ancients; ''Wen'' shouldn't be taken as a source of values in and of itself, but as a way of approaching an understanding of the ancient sages believed and carried out. Deriving a sense of values would happen, for Zhu Xi, through both studying the ancient texts from this point of view and from studying phenomena in the world. 

The critical figure in this process was the "gentleman" (''Junza'') that Confucius upheld as a model of good values for everyone to follow. In practice, this meant the ''shi'', the educated elite. The ''junza'' would essentially be the invidual who puts the quest for moral values into practice; he sought to develop and cultivate his own moral qualities, while being engaged in the process of making the world a better place. In that process, he would have to undertake studies, but also what Zhu Xi called the "investigation of things" (''gé wù'', 格物). These practices would prepare the ''junza'' to be a good person, lead a good family life, and thus be able to carry on the affairs of the state.

Zhu Xi did not reject the textual tradition, but he did take a very critical approach to it, unlike the Northern Song elite. He did not care much to immerse himself in the textual tradition and absorb values from it, but he did say there were elements of value in this tradition. He was uncomfortable with the "commentarial" tradition; the body of texts which sought to interpret the teachings and writings of the Ancient over the past millenia and a half. Zhu Xi thought that these later texts obscured the meanings of what the original authors had actually said (or actually intended to say). He thus advocated a return to the classics, engaging directly with them.

One of Zhu Xi's legacies was the selection of four texts he considered to be fundamental to his philosophy, making them the centerpieces of his educational program. The Confucian classics in Chinese history varied throughout the eras, with there at times being 5, 8, or even 13. Two of Zhu Xi's four texts were the ''Analects of Confucius'' (written by his students after his death) and the ''book of Mencius'' (Confucius' most famous follower, written a century and a half later). These two texts had always been in the classical canon, and were full-length books. The other two texts he considered fundamental were chapters taken from a longer work called the ''Liji'', which is a record of ritual activities of the early Zhou dynasty. These two chapters of the ''Liji'' are called ''the doctrine of the Mean'' and ''the Great Learning''.<ref name=":017" />

=== The Great Learning ===
This chapter of the ''Liji'' perhaps encapsulates Zhu Xi's philosophy best. The ''Great Learning'' is not a long text, but it follows a very careful course of development, starting by referring back to the ancients (who wished to bring order to the world). There is a short preface before that to explain what the ''great learning'' (the Dao) is: manifesting one's virtue in the world, or in practical terms, "knowing when to stop" (as quoted from the book).

The ancients who wished to bring order to the world, according to the Great Learning, firstly had to govern well. To achieve that, they followed a logical sequence, which can be explained in this manner: they first had to get their family to be well-ordered, properly organized and run. But to achieve that, they first had to rectify and cultivate themselves. To achieve that, they tried to get their consciousness clear, which they realized required them to extend their knowledge. Finally, to extend their knowledge, they started by engaging in the ''investigation of things'' (''gé wù'').<ref name=":017" />

==== Process of the Dào Xué ====
When things are investigated ''correctly'', then knowledge is expanded. That sequence is essentially the entire basis of the ''dào xué'', but it should not be seen as a step-by-step program; Zhu Xi's teachings were especially well-preserved by his students who took extensive notes of his lectures. In these records, he made it quite clear that all these activities actually need to be undertaken at the same time, they cannot be separated and must be pursued at all times, even when one is alone (which Zhu Xi got from Confucius). This was especially important to Zhu Xi as the Daoxue was not simply a matter of public affairs or appearances, but something one had to pursue for themselves.

The path the this learning takes is a process of moral development that, for Zhu Xi, would essentially make one into a "gentleman", or ''Junza''. For Confucius, there was nothing that inherently restricted this practice to one particular group within society. Indeed, the Great Learning ends with the following phrase: "for everyone, from the son of heaven down to an ordinary farmer, this should be the way"; the implication being that self-cultivation is a responsibility that all individuals in society have, although Zhu Xi did not emphasize this aspect in his writings.<ref name=":017" />

=== Qi ===
The social and economic context Zhu Xi lived in, of the Southern Song dynasty, likely influenced his writing, which can be seen to some extent in his writing. The idea of an individual moral responsibility corresponds, for example, to the emergence of a more market-oriented economic system, in which individuals participate in exchange and in which a "marketplace of ideas" might be inferred. In that place of ideas, the individual would advocate his own moral understanding and insights: Zhu Xi's system is not one that imposes a dogma or truth from the top-down, but one that challenges individuals to cultivate themselves morally and bring out their own moral understanding.

In a sense, everything shares in ''Li'' (the seeking out of natural patterns from which one can derive universal principles) . Zhu Xi asks, for example, the question of why some people are morally better than others: if everyone shares in Li, why aren't people inherently good?

Zhu Xi explained this through the concept of ''Qi'', which, he argued, could not be separated from ''Li''. Qi is often referred to as an "energy" system within the body, but for the cosmological thinkers, ''Qi'' is the fabric of material reality. If ''Qi'' were the base, then ''Li'' would be the superstructure.

The process of self-cultivation is one that clarifies one's ''Qi''; the clearer one's ''Qi'' is, the more directly will natural principles (''Li'') be manifested. To the degree that one's ''Qi'' is "cloudy", ''Li'' will be obscured to them.

The cultivation of the individual is therefore a process to more directly manifest ''Li'', which is done through being in harmony with the ''Dao''.<ref name=":017" />

=== Legacy ===
''Dào xué'' itself never became a dominant or even mainstream philosophy during Zhu Xi's lifetime, but it became so very rapidly ''after'' his death; by the 1240s, Daoxue was given official recognition by the imperial state and even after the Mongol conquest, Zhu Xi's interpretation of Confucianism came to be the official line followed by the empire, even being given central place in the imperial examination system.

==The rise of the Mongols==
While China was continuing on, divided between the Jin and Song dynasties, a new power was beginning to arise out in the Asian steppes, the Mongol empire led by [[Genghis Khan]] (also known as Temujin).<ref name=":018">{{Citation|author=Dr. Ken Hammond|year=2004|title=From Yao to Mao: 5000 years of Chinese history|chapter=Lecture 20: The Rise of the Mongols|publisher=The Teaching Company}}</ref>

=== Temujin ===
The Mongols lived nomadically and semi-nomadically, moving from summer to winter pastures throughout the year in the great grasslands (also called steppes) of inner Asia, areas in which they had lived for centuries by that point. They subsisted by raising sheep, goats and horses.

The political landscape of the Mongol people can be described as low-intensity. Leadership was organised on the basis of a family (or tribal) affiliation but seldom came together as a coherent force.

Temujin was born in the 1160s, the son of a minor tribal chieftain. His father was murdered early in his life. After this, Temujin and his family were forced to flee to remote hills. As Temujin grew up, he conceived a desire to avenge his father and an ambition to unite the Mongol people. In the 1180s, he began to pursue his ambitions: he led his family back to society and ruthlessly murdered his older brothers so that he would be the senior male member of his tribe. At 16, he claimed a bride by the name of Börte who had been promised to him in an agreement between his father and her father when Temujin was just an infant. Although his father had been murdered and the promise of marriage could have been cancelled, the bride's family agreed to honor the contract. Moreover, the bride's father gave Temujin a sable cloak, which was a very valuable item which became a symbol of his power in later years.

Through his family connections and charisma, Temujin was afterwards able to form alliances and build up a following. He received a reputation as a strong and dynamic fighter and leader. In one instance, his wife had been kidnapped in a raid committed by other Mongols, as happened from time to time. In response, Temujin launched a raid and succesfully brought back his wife, impressing his peers greatly.

In 1190, Temujin was named ''khan'', which is a title reserved for a tribal leader. Over the next 10 years, he and other Mongol leaders would at times collaborate and at times fight against each other, but by 1200 he had built a foundation from which to unite all the Mongol tribes. This was not accepted easily by other leaders who did not want to see one individual dominate all other tribes. When this happened in the past and someone would become too strong, the other tribes would ally together to cut them down to size.

Confrontations came to a head in 1204 when Temujin was defeated in battle. Withdrawing from the battle with only a few thousand of his soldiers, he waited for the enemy to celebrate his defeat -- knowing that they would get drunk and be unable to mount a defense. Temujin rode back with his army three days later and assaulted the camp. His assault was successful, and he was able to get rid of essentially all of his competition.

In 1206, he convened a ''kurultai'', an assembly during which all tribes came together to discuss politics. There he was elected to be Genghis Khan, or "oceanic leader", the king of kings.<ref name=":018" />

=== Great raids ===
Leadership of the Mongols was based on the ability to distribute goods seized during raids. Having unified the Mongols, raids between tribes were forbidden, but a new source of revenue had to be found to replace it, and so the Mongols started preparing large raids on their immediate neighbours.

They eventually started raiding a very enticing target: the Jin dynasty, which controlled the agricultural wealth of the North China plain.

Two keys to the success of the Mongols' conquests were their cavalry and their ruthlessness. They had bred over centuries horses capable of marching for days on end, which made the Mongol army highly mobile (to the point, Dr. Ken Hammond notes, that they could essentially show up at a city overnight). Secondly, when the Mongols sieged a settlement, they would offer two choices: either surrender and only a portion of the city would be killed, with most of the men being incorporated into the Mongol army, or refuse to surrender and everyone would be killed. It is exemplified historically that the Mongols were very strict at enforcing this ultimatum, almost never deviating from it.

They also developed a very highly refined system of military organization. Army groups were organized on the decimal system, and as the army expanded they simply created new units with some Mongol officers at their head. In this way they were able to continually expand their army.<ref name=":018" />

The Mongols conquered vast amounts of land under Temujin, going as far down to Persia and west to Russia. On the way, they started raiding into Tibet and there won the submission of the Tibetan monastic leaders, after which Tibet was incorporated into the Empire, with some Mongols even adopting Tibetan Buddhism.

=== Death of Temujin ===
In 1227, 20 years after the Mongols had started their great raids, Temujin died as he was bringing his forces back towards Mongolia. When he died, all the Mongol armies had to return home for another ''kurultai'' and elect their new leader. This process took over 2 years, and Temujin's son, Ugedei, was elected as Genghis Khan and presided over a second great age of conquest.

It was under Ugedei's leadership that the Mongols ventured into China, destroying and incorporating the Jin state 1234 and move down into the Southern Song.

Ugedei died in 1241, leaving a decade-long period of uncertainty after which the Mongol empire was divided among four of Temujin's grandsons.<ref name=":018" />

=== Partition of the Mongol Empire ===
Batu Khan took over Russia and Ukraine, calling his territory the Khanate of the Golden Horde -- the successors of which later became the Cossacks. Hulagu controlled Persia, with his descendants being known as the Ilkhan and converting to Islam which was the religion of Persia, emerging later as the Mughals (who invaded India until 1857). In the third territory in central Asia, Chagadai took over Samarkand, naming his holdings the Khanate of Chagatai. One of his descendants was Tamerlane, a great conqueror in the 15th century who almost conquered China. Finally, in China itself, Kublai became the Khan there and lorded over not only the Southern Song dynasty but Korea as well. He also made two attempts at invading Japan which never succeeded.

This age of conquest was unprecedented; they brought together territories that had never been controlled by a single power in history. This created conditions which had never been seen before; for example, it became safe to travel all the way from the Mediterranean to the Pacific under the protection of the Mongols. There was much more interaction amongst different parts of East Asia, Eastern Europe and West Asia (the Middle East).<ref name=":018" />
