In the words of scholar Charlotte M. Gradie, "for the Spanish, the Chichimecas were a wild, nomadic people who lived north of the Valley of Mexico.
They had no fixed dwelling places, lived by hunting, wore little clothes and fiercely resisted foreign intrusion into their territory, which happened to contain silver mines the Spanish wished to exploit.
"[1] Gradie noted that Chichimeca was used as a broad and generalizing term by outsiders, writing, "[it] was used by both Spanish and Nahuatl speakers to refer collectively to many different people who exhibited a wide range of cultural development from hunter-gatherers to sedentary agriculturalists with sophisticated political organizations.
"[3] In modern times, only one ethnic group is customarily referred to as Chichimecs, namely the Chichimeca Jonaz, a few thousand of whom live in the state of Guanajuato.
He had received an encomienda near Durango and fought in the wars against the Chichimec peoples: the Pame, the Guachichil, the Guamare and the Zacateco, who lived in the area known at the time as "La Gran Chichimeca."
