Xilotepec

Xilotepec was the capital of an Otomi lordship on the northern rim of the Valley of Mexico, with subject towns in southern Queretaro and Hidalgo. In 1337 it was an independent mountain power on the routes north.

Tenochtitlan conquered it in 1379 under Acamapichtli, but its people regained autonomy. After another invasion under Axayacatl, Ahuitzotl completed the conquest in 1487. During the Spanish invasion its lord and his kinsman Conin sided with Hernan Cortes; in 1531 Conin, baptized Hernando de Tapia, led the founding of Santiago de Queretaro.
