The Peoria tribe was one of the Native Americantribes 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 removed to land in Kansas. After the Civil War, most of the confederated tribe was removed to land in Indian Territory (now Oklahoma). The tribe lost federal recognition in 1959, but regained it in 1978.
