The Omaha tribe began as a larger Eastern Woodlands tribe comprising both the Omaha, Ponca and Quapaw tribes. The Omaha (Dhegihan) migration route to Nebraska as understood by J. Never known to take up arms against the U.S., the Omaha assisted the U.S. Omaha, Nebraska, the largest city in Nebraska, is named after them. They controlled the fur trade and access to other tribes on the Upper Missouri River. Developing 'The Big Village' ( Ton-wa-tonga) about 1775 in current-day Dakota County in northeast Nebraska, the Omaha developed an extensive trading network with early European explorers and French Canadian voyageurs. After pushing out other tribes, the Iroquois kept control of the area as a hunting ground.Ībout 1770, the Omaha became the first tribe on the Northern Plains to adopt equestrian culture. They were also related to the Siouan-speaking Osage, Quapaw, and Kansa peoples, who also migrated west under pressure from the Iroquois in the Ohio Valley. The latter were part of the Omaha before splitting off into a separate tribe in the mid-18th century. The Omaha speak a Siouan language of the Dhegihan branch, which is very similar to that spoken by the Ponca. The Omaha people migrated to the upper Missouri area and the Plains by the late 17th century from earlier locations in the Ohio River Valley.
