History
Early history
For millennia, the Great Plains of North America was inhabited by nomadic Native Americans. Numerous tribes lived on the Great Plains including the: Arapaho, Cheyenne, Comanche, Sioux, Ute, Otoe, Kansa, Kiowa, Osage, Omaha, Ponca, Pawnee, and Wichita. These tribes were sustained by a seemingly inexhaustible supply of buffalo that then numbered in the tens of millions.
