Cozamaloapan
Cosamaloapan was the head town of a pre-Hispanic Nahua lordship, located on the Papaloapan river in the lowlands of central Veracruz.
Mexica armies conquered it between 1452 and 1457, and its tribute was delivered at Tuxtepec, where a garrison was stationed. After the Spanish conquest, Cosamaloapan became a colonial district around 1534; in 1560 it merged with Guaspaltepec into a larger district. Reforms in 1786 made it a partido of the Intendancy of Veracruz.
