Arapaho es Arapaho (culture or style) en

Culture or style of a North American Indian tribe of Algonquian linguistic stock who lived during the 19th century along the Platte and Arkansas rivers of what are now the U.S. states of Wyoming, Colorado, Nebraska, and Kansas. Their oral traditions suggest that they once had permanent villages in the Eastern Woodlands, where they engaged in agriculture. Because of pressure from tribes to the east, the Arapaho gradually moved westward, abandoning farming and settled life during the process. They split into northern (Platte River) and southern (Arkansas River) groups after 1830.
