Tlalcozauhtitlan

Tlalcozauhtitlan was a town in northeastern Guerrero, near Teopantecuanitlán in the Balsas basin. It lay where Nahua, Chontal and Mixtec regions met.

Moctezuma I conquered it along with Tlachco in 1458. Under Aztec rule it became the seat of a tribute province, recorded on folio 10v of the Matrícula de Tributos. A sixteenth-century report listed the town with Iguala among speakers of the little-known Tuxtec tongue; the district also used Chontal and Nahuatl, the language of its elite.
