The Cheyenne were famous as a hunter-warrior Indian tribe of the Great Plains. They had been sedentary farmers in northeastern Minnesota, until migrating westward in the late 1600s. They later settled along the Cheyenne River of North Dakota. Dislodged by the Ojibwa in the 1770s, they moved southwestward. The Lewis and Clark expedition encountered them as nomadic buffalo-hunters in the Black Hills of South Dakota.
