Itzohcan

Itzocan was a Nahua city-state in the Coatlalpan lowlands of southwestern Puebla. Its ruling dynasty had ties of marriage and descent with those of Tenochtitlan and neighbouring Huaquechula; its people were Nonoalca.

The Aztec Empire conquered Itzocan, stationed a garrison there and made it answer to Tepeaca. Spanish forces entered Coatlalpan between 1521 and 1525, and the name Itzocan gradually became Izúcar. After Mexican independence the city added the name of the insurgent Mariano Matamoros.
