Plains Indians Plains Indians, Interior Plains Indians or Indigenous people of the Great Plains and Canadian Prairies are the Native American tribes and First Nation band governments who have traditionally lived on the greater Interior Plains (i.e. the Great Plains and the Canadian Prairies) in North America. Their historic nomadic culture and development of equestrian culture and resistance to domination by the government and military forces of Canada and the United States have made the Plains Indian culture groups an archetype in literature and art for American Indians everywhere.
Chichimeca 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 and its pejorative sense was adopted by the Spanish. 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."
