The Great Plains Tribes are a group of Native American nations that historically inhabited the vast grasslands of North America, primarily in areas that are now part of the United States and Canada. These tribes, including the Lakota, Cheyenne, and Pawnee, were known for their nomadic lifestyle, following the herds of bison that roamed the plains. These tribes developed rich cultures with unique languages, traditions, and social structures. They relied heavily on the bison for food, clothing, and shelter, and their spiritual beliefs were closely tied to the natural world. The Great Plains Tribes played a significant role in the history of North America, particularly during the westward expansion of settlers in the 19th century.
