It is believed that the Tecuexe derived from the dispersion of Zacateco groups from La Quemada. Like the Zacatecos, the Tecuexe were a tribe belonging to the generic "Chichimeca" peoples. It is known that they settled next to rivers which they used to their advantage to grow beans and corn. They were also expert artisans, carpenters and musicians. Toribio de Benavente Motolinia wrote "in any place… all know to work a stone, to make a house simple, to twist a cord and a rope, and the other subtle offices that do not require instruments or much art." The Tecuexe were known for their fierceness and cruelty towards their enemy. They were known to be so brave, it is said, that once, when the Mexica (Aztecs) came from Chicomostoc, Zacatecas to take control of Xolotl, (and course on to the lagoon where they found an eagle devouring a serpent) they attacked the settlers of Acatic, Teocaltiche, Mitic, Teocaltitán and Xalostotitlán, but in Tepatitlán, when they encountered the Tecuexe, having heard of their legendary cruelty, the Mexica avoided facing them.
