Teotlalpan

Teotlalpan (Nahuatl: teōtlālpan or teuhtlālpan) was the pre-Columbian name of a region in the north of Valley of Mexico comprising what is today the Mezquital Valley in the state of Hidalgo and adjacent areas in the State of Mexico. The region was one of two regions settled by Otomí people, the other being the region around Jilotepec and Tula, Hidalgo. In the 18th century the name of the main part of the region came to be known as Mezquital.
