The Plains culture area comprises the vast prairie region between the Mississippi River and the Rocky Mountains, from present-day Canada to the Gulf of Mexico. Before the arrival of European traders and explorers, its inhabitants—speakers of Siouan, Algonquian, Caddoan, Uto-Aztecan and Athabaskan languages—were relatively settled hunters and farmers. After European contact, and especially after Spanish colonists brought horses to the region in the 18th century, the peoples of the Great Plains became much more nomadic.

Groups like the Crow, Blackfeet, Cheyenne, Comanche and Arapaho used horses to pursue great herds of buffalo across the prairie. The most common dwelling for these hunters was the cone-shaped teepee, a bison-skin tent that could be folded up and carried anywhere. Plains Indians are also known for their elaborately feathered war bonnets.

As white traders and settlers moved west across the Plains region, they brought many damaging things with them: commercial goods, like knives and kettles, which Indigenous people came to depend on; guns; and disease. By the end of the 19th century, white sport hunters had nearly exterminated the area’s buffalo herds. With settlers encroaching on their lands and no way to make money, the Plains natives were forced onto government reservations.
