Oztoman

Oztoman, also called Oztuma, lay in the Cohuixca country of Tierra Caliente, between the Valley of Mexico and the Purépecha kingdom. The settlement preceded the Mexica frontier forts built there.

Between 1440 and 1469 Moctezuma I subdued Oztuma and neighbouring towns. The Mexica built a garrison of five forts to watch the Purépecha border and suppress rebellious Chontal communities. For decades it faced the Purépecha garrison at Cutzamala, until Purépecha warriors stormed the forts in 1520, an episode recorded in the sixteenth-century Relación de Oztuma.
