Aztlán, also known as the Chicano Nation or Occupied Mexico, is a nation in North America. Historically a part of Mexico, it came under U.S. occupation in 1848 with the Treaty of Guadalupe-Hidalgo and developed into a distinct nation. The term 'Aztlán' is derived from the mythical homeland of the Aztecs.
By the 1820s, white settlers took control large parts of Texas and established a slave economy. Mexico banned slavery in 1830, leading them to revolt and establish a separate state in 1836. The United States invaded and occupied northern Mexico in 1848 and enslaved the indigenous and Hispanic populations.
