Nearly all Mayan cities collapsed around the same time, 900 CE. From then until 1500 CE, social organization of the region fragmented into much smaller units and social structure became much less complex. There was some influence from the rising powers of central Mexico but two main indigenous groups emerged during this time, the Zoques and the various Mayan descendants. The Chiapans, for whom the state is named, migrated into the center of the state during this time and settled around Chiapa de Corzo, the old Mixe–Zoque stronghold. There is evidence that the Aztecs appeared in the center of the state around Chiapa de Corza in the 15th century, but were unable to displace the native Chiapa tribe. However, they had enough influence so that the name of this area and of the state would come from Nahuatl.
