Mayan civilization
In the north, the Maya civilization kept going. Other cultures started mixing with Mayan culture much more. Some of the important sites in this time were Chichen Itza, Uxmal, Edzná, and Coba. At some point, the families who ruled over Chichen and Uxmal got weaker and the rulers in the city of Mayapan ruled all of the Mayan civilization in the Yucatán peninsula until there was a revolt in 1450. After the revolt, the whole area broke up into different cities who fought against each other,  until the Spanish conquest of Yucatán.
