The Kaw Nation (or Kanza or Kansa) is a federally recognized Native American tribe in Oklahoma and parts of Kansas. It comes from the central Midwestern United States. It has also been called the "People of the South wind", "People of water", Kansa, Kaza, Konza, Conza, Quans, Kosa, and Kasa. Their tribal language is Kansa, classified as a Siouan language.
The toponym "Kansas" was derived from the name of this tribe. The name of Topeka, capital city of Kansas, is said to be the Kaw word Tó Ppí Kˀé meaning "a good place to grow potatoes". The Kaw are closely related to the Osage Nation, with whom members often intermarried.
The Kaw Nation's headquarters is in Kaw City, Oklahoma, and the tribal jurisdictional area is within Kay County, Oklahoma. The elected chairwoman is Lynn Williams currently serving a four-year term. Of the 3,126 enrolled members, 1,428 live within the state of Oklahoma.
The estimated annual economic impact of the tribe is $200 million. Kaw Nation owns the Kanza Travel Plaza; Woodridge Market; Smoke Shop I, and II; SouthWind Casino; including a bingo hall, and an off-track wagering facility; and SouthWind Casino Braman, which opened September 2014. The tribe also operates the Kanza Health Clinic, Kanza Wellness Center, Kaw Nation School Age Enrichment Center, Kanza Museum, Kaw Nation Environmental Department, Kaw Nation Police Department, Kaw Nation Social Service and Educational Department, Kaw Nation Emergency Management Department, Kaw Language Department, and the Kaw Nation Judicial Branch. The Kaw Nation Judicial Branch includes a domestic violence program. The Kaw Nation operates its own Housing Authority, library, Title VI Food Services, and issues its own tribal vehicle tags. The Kanza News, the newsletter of Kaw Nation, is published quarterly.
The Kaw is a member of the Dhegiha branch of the Siouan language family. Oral history indicates that the ancestors of the five Dhegiha tribes migrated west from the east, possibly somewhere around the Ohio Valley.
