Nahua peoples
Chichimeca was the name that the Nahua peoples of Mexico generically applied to a large number of bands and tribes of nomadic and semi-nomadic peoples who inhabited the north of modern-day Mexico and southwestern United States, and carried the same sense as the European term "barbarian". The name was adopted with a pejorative tone by the Spaniards when referring especially to the hunter-gatherer peoples of northern Mexico. In modern times only one ethnic group is customarily referred to as Chichimecs, namely the Chichimeca Jonaz, although lately this usage is being changed for simply "Jonáz" or their own name for themselves ""Úza".
