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 living in tipis, which were easy to set up and take down. Historically, the Arapaho were divided into two main groups: the Northern Arapaho and the Southern Arapaho. Today, many Arapaho people are enrolled in the Northern Arapaho Tribe in Wyoming and the Southern Arapaho Tribe in Oklahoma, where they continue to preserve their cultural heritage and traditions.
