Temascaltepec
Temascaltepec was a town in the southern Toluca highlands beneath the Nevado de Toluca. Its Nahua, Matlatzinca and Mazahua inhabitants may originally have depended on the neighbouring polity of Texcaltitlán.
In the 1470s the Aztec emperor Axayacatl conquered Temascaltepec and made it the seat of a strategic frontier province. Its garrisons faced the Purépecha to the west, across the Tierra Caliente, on the border between the rival powers.
