The Arapaho people are a Native American tribe originally from the Great Plains region of North America. They traditionally lived in areas that are now parts of Colorado and Wyoming. The Arapaho were known for their nomadic lifestyle, following buffalo herds and relying on them for food, clothing, and shelter. Historically, the Arapaho were divided into two main groups: the Northern Arapaho and the Southern Arapaho. They spoke the Arapaho language, which is part of the Algonquian language family. Today, many Arapaho people continue to preserve their culture and traditions while also participating in modern society.
