The Kiowa are a nation of American Indians of the Great Plains. They migrated from the western Montana southward into the Rocky Mountains in Colorado in the 17th and 18th centuries, and finally into the Southern Plains by the early 19th century. In 1867, the Kiowa moved to a reservation in southwestern Oklahoma. Today they are federally recognized as Kiowa Tribe of Oklahoma, with 12,000 members. They are headquartered in Carnegie, Oklahoma. The Kiowa language is still spoken today and considered part of the Kiowa Tanoan language family.
