When the Spaniards started exploring Guanajuato in the 1530s and 1540s, they encountered several nomadic tribes occupying the area which they referred to as La Gran Chichimeca, which included large parts of Guanajuato, Jalisco, Zacatecas, San Luis Potosí, Aguascalientes and Durango.

The tribes within the Guamare area included the Copuces and the Guaxabanes in the north. Beyond San Felipe lived the Guachichiles, the largest and most extensive Chichimec group that occupied large parts of what are now known as Zacatecas, San Luis Potosí, as well as smaller portions of eastern Jalisco and western Guanajuato.

The Otomí Indians (The Sierra Nahñu) The Otomíes were a Chichimeca tribe, occupying present-day Querétaro, Guanajuato, Hidalgo and parts of the state of México. At one time, the Otomí held a great deal of power and prestige throughout east central Mexico.

The Guamare people were an indigenous people of Mexico, who were established mostly in Guanajuato and at the border of Jalisco. [1] They were part of the Chichimecas, a group of a nomadic hunter-gatherer culture and called themselves Children of the Wind, living religiously from the natural land.
