Peoria
An Algonquian people, whose ancestors came from what is now Illinois, Michigan, Missouri, and Ohio, their history goes back as far as once part of the Cahokia culture of Mound builders. The name "Peoria" come from their name for themselves in the Illinois language, Peewaareewa, meaning "Comes carrying a pack on his back. Their ancestral lands were in Illinois, Michigan, Ohio and Missouri, but most began to migrate into Missouri Territory by the mid 1700's. In 1818, the Treaty of Edwardsville forced them to cede their lands in Illinois and the Treaty of Lewisville, in 1832, ceded their Missouri lands in exchange for land in Kansas, near the Osage River.
Disease and war drastically reduced the tribe's numbers, so the members of the Kaskaskia, Peoria, Piankeshaw, and Wea tribes formed a confederacy under the Peoria name in 1854. After the Civil War, most of the confederated tribe signed the 1867 Omnibus Treaty, which purchased land from the Quapaw tribe and relocated the majority of the tribe from Kansas to Indian Territory. Today, the federally-recognized tribe is based in Miami, Oklahoma and has more than 2800 tribal members.
