Tepecoacuilco

Tepecoacuilco was a town in the Mezcala basin of northern Guerrero. Its Nahuatl name meant the hill of the painted snakes; it belonged to the lordship of Coixcatlalpan, founded by Nahua-Coixca invaders.

Mexica armies raided under Itzcoatl in 1435 and built a fortress in 1438. After Moctezuma I's campaigns it became the seat of a tributary province; the Codex Mendoza records cotton mantles, copper axes and other goods delivered by the town and its neighbors. Gonzalo de Sandoval took it in 1529, and Augustinian friars began evangelization in 1533.
