Aztec-Period Political and Economic Organization of Western Morelos, Mexico

Abstract

The Tlahuica, a Nahua ethnic group, arrived in what is now western Morelos and conquered several preexisting towns circa a.d. 1100. Members of Tlahuica elite lineages took control of irrigable land and founded altepeme (small city-states). As population increased, segmentation occurred until there were 32 altepeme. The elite's control of the irrigable land was the basis for collecting tribute consisting of cotton cloth. The 32 altepeme in western Morelos became part of three señoríos (regional centers) comprised of multiple altepeme by a.d. 1400: Cuauhnahuac, Tlaquiltenango, and Xiutepec. Coatlan, located in the southwestern part of western Morelos, remained an independent polity separate from the three señoríos. The 32 altepeme were conquered by the Triple Alliance in the 1430s and 1450s, putting a halt to further conquests by these señoríos and leaving Coatlan as an independent buffer state between the Tlahuica señoríos and Chontal polities to the southwest. The Triple Alliance did not displace the local population in western Morelos or send colonists from the Basin of Mexico, as they did in non-Nahua provinces of the empire.
