Of all the Chichimeca natives, the Guachichiles occupied the most extensive territory. Most of their home laid in the present state of Zacatecas, but they also occupied parts of northern Jalisco. They were considered both warlike and brave.
Origin of Name
The Guachichiles were known to paint their bodies, hair, and faces in red dye. For this reason they were called "guachichile" by the Mexica, meaning "heads painted of red".
