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.
Fur trade in Montana The fur trade in Montana was a major period in the area's economic history from about 1800 to the 1850s. It also represents the initial meeting of cultures between indigenous peoples and those of European ancestry. British and Canadian traders approached the area from the north and northeast focusing on trading with the indigenous people, who often did the trapping of beavers and other animals themselves. American traders moved gradually up the Missouri River seeking to beat British and Canadian traders to the profitable Upper Missouri River region.
