Peoria Tribe of Indians of Oklahoma

The Peoria Tribe of Indians of Oklahoma was one of the Native American tribes that formed the Illiniwek tribal group in what is now the Midwest of the United States of America. After being decimated by disease and wars, the members of the Kaskaskia, Peoria, Piankeshaw, and Wea tribes were confederated under the Peoria name and relocated to land in Kansas. After the Civil War, most of the confederated tribe was relocated to land in Indian Territory.

The tribe lost federal recognition in 1959, but regained it in 1978.
