This group of natives in North America were indigenous to the Interior Plains, historically nomadic, and relied on bison hunting.
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.
Comanche history Forming a part of the Eastern Shoshone linguistic group in southeastern Wyoming who moved on to the buffalo Plains around AD 1500 (based on glottochronological estimations), proto-Comanche groups split off and moved south some time before AD 1700. The Shoshone migration to the Great Plains was apparently triggered by the Little Ice Age, which allowed bison herds to grow in population. It is not clear why the proto-Comanches broke away from the main Plains Shoshones and migrated south. That move may have been inspired as much by the desire for Spanish horses released by the Pueblo Revolt of 1680 as by pressures from other groups drawn to the Plains by the changing environment.
