Omaha Indians
Omaha Indians, a tribe of the Siouan linguistic group. It is closely associated with the Poncas, Kansas, Osages, and Quapaws. Omahas live on or near the Omaha reservation in northeastern Nebraska, where they farm and operate a recreation area. The Omahas settled in their present locality, where Lewis and Clark found them in 1804, after living in eastern Missouri, Minnesota, and South Dakota. The Omahas were often at war with the Sioux, but had a generally peaceful relationship with whites. In 1854, they ceded their lands west of the Missouri River to the federal government and were settled on the Nebraska reservation.
