In addition, they cultivated and processed such crops as squash, beans, corn, and pumpkins. The women processed meat and used hides, bone, horn, and other the parts of the animals for tools, clothing, etc. By tradition, the chief of the Bear Clan was the principal leader of the tribes. Each clan had a leader, and together the clan chiefs formed a tribal council. Tribal members had exogamous marriage practices young people had to marry outside their clan. Their joined society was patrilineal and comprised seven to ten clans, each with distinct assigned responsibilities. In the 19th century, the Missouria and the Otoe established permanent villages consisting primarily of earth lodges, but also occasionally tipis and bark lodges. In 1796, some surviving Missouria joined the Osage and Kaw tribes, while 80 Missouria joined the Otoe. They also lost people to frequent warfare with enemies, such as the Sac and Fox. ĭuring the 18th century the Missouria people suffered from epidemics of new infectious diseases, especially smallpox, which killed many in the tribe. This area was later set aside for them as the Otoe Reservation. After contact and continued pressure by European-Americans, they migrated to the territory of later Nebraska, settling near the Platte River. In 1700, Pierre Le Moyne d'Iberville wrote that the Otoe and the Iowa lived with the Omaha tribe in territory to the west of the Mississippi and Missouri rivers.

Jacques Marquette, the French explorer, included them on a 1673 map, placing the Otoe near the Des Moines and upper Iowa rivers. They first came into contact with Europeans in late 17th century. Meanwhile, the Otoe settled along what is now the Iowa– Minnesota border. By the late 17th century, the Missouria had settled near the Missouri and Grand rivers in what became Missouri. In the 16th century, the Iowa, Otoe, and Missouria broke away and moved to the south and west. They had once been a single tribe that included the ancestors of the Ho-Chunk, Winnebago and Iowa tribes. The Otoe and Missouria tribes both originated in Wisconsin in the Great Lakes region. Their language, the Chiwere language, is part of the Siouan language family. The tribe is made up of Otoe and Missouria peoples. The Otoe–Missouria Tribe of Indians is a federally recognized tribe, located in Oklahoma. Tribal religion, Native American Church, Christianity
