In prehistoric times they lived with the Kansa, the Ponca, the Omaha, and the Quapaw in the Ohio valley, but by 1673 they had migrated to the vicinity of the Osage River in Missouri. They often conducted war against other Native Americans, and in the early 18th cent. allied themselves with the French against surrounding tribes, such as the Illinois.

In 1802, according to Lewis and Clark, three groups constituted the Osage—the Great Osage, on the Osage River; the Little Osage, farther up the same river; and the Arkansas band, on the Vermilion River, a tributary of the Arkansas. They then numbered some 5,500. By a series of treaties begun in 1810 the Osage ceded to the United States their extensive territory in Missouri, Arkansas, and Oklahoma, and they moved to a reservation in N central Oklahoma. They have since been given the right to own their land individually. The discovery of oil on their reservation land in the early 20th cent., plus their landholdings, contributed to the prosperity of the Osage. In 1990 there were over 10,000 Osage in the United States. The Osage Museum in Pawhuska, Okla., the oldest continuous tribal museum in the country, documents their history.
