"Time of Origin" column is ahistorical
According to Historial Materialism, the periods of world history can be defined by the modes of production. This page implies that each mode of production can neatly fall into a period of world history (Medieval, Renaissance) but the truth is opposite. The medieval period is part of the feudal period, the feudal period is not part of the medieval period. It is also eurocentric to use these terms.
