Otoe
The Otoe (aka Oto or Oh toh) were once part of the Siouan tribes of the Great Lakes region, commonly known as the Winnebago. At some point; however, they began to migrate southwest where they were located just north of the Missouri River and west of the Mississippi River in what is now northern Missouri and Iowa. This group eventually split into at least three distinct tribes: the Ioway, the Missouria and the Otoe, who finally settled near the Platte River in southeastern Nebraska. Following the Louisiana Purchase, the Otoe were the first tribe encountered by the Lewis and Clark Expedition, meeting at a place that would become known as Council Bluffs. In the earliest times, the Oto lived in villages and practiced farming, but eventually they adopted the culture of the plains. In 1881 they moved to a reservation in Oklahoma with the Missouria. Today the Otoe-Missouria remain a federally recognized tribe, based in Red Rock, Oklahoma.
