The Plains Indians

Plains Indians are the Native American tribes and First Nations band governments who lived on the plains and rolling hills of both the Great Plains and Canadian Prairies in North America. Their equestrian culture and resistance to domination by Canada and the Midwestern United States have made the Plains Indians an archetype in literature and art for American Indians everywhere. Plains Indians are usually divided into two broad classifications which overlap to some degree. The first group became fully nomadic and dependent upon the horse during the 18th and 19th centuries, following the vast herds of buffalo, although some tribes occasionally engaged in agriculture, growing tobacco and corn primarily. These include the Blackfoot, Arapaho, Assiniboine, Cheyenne, Comanche, Crow, Gros Ventre, Kiowa, Lakota, Lipan, Plains Apache (or Kiowa Apache), Plains Cree, Plains Ojibwe, Sarsi, Nakoda (Stoney), and Tonkawa.

The second group of Plains Indians includes the aboriginal peoples of the Great Plains, as well as the Prairie Indians who come from as far east as the Mississippi River. These tribes were semi-sedentary, and, in addition to hunting buffalo, they lived in villages, raised crops, and actively traded with other tribes. These include the Arikara, Hidatsa, Iowa, Kaw (or Kansa), Kitsai, Mandan, Missouria, Omaha, Osage, Otoe, Pawnee, Ponca, Quapaw, Wichita, and the Santee Dakota, Yanktonai and Yankton Dakota.
