Chichimeca was the name that the Nahua peoples of Mexico generically applied to nomadic and semi-nomadic peoples who were established in present-day Bajio region of Mexico. Chichimeca carried the same sense as the Roman term "barbarian" to describe Germanic tribes. The name, with its pejorative sense, was adopted by the Spanish Empire. For the Spanish, in the words of scholar Charlotte M. Gradie, "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."
