Xaltocan

Xaltocan was an Otomi city-state on an island in the northern Valley of Mexico. In 1337 it was ruled by Pantictzin and fought a long rivalry with the neighbouring Nahua city of Cuauhtitlan.

Around 1395 Cuauhtitlan enlisted Tezozomoc of Azcapotzalco and the Mexica of Tenochtitlan to storm the island. Its Otomi inhabitants fled, and Nahuatl speakers resettled it. Xaltocan later sent woven blankets as tribute to the Aztec empire, until Hernán Cortés's army sacked and burned it in 1521.
