By the 17th century, the Osage and other Siouan tribes had been forced to move west from the Ohio Valley across the
Mississippi River. The Osage became established as a powerful nation in the areas of present-day Missouri and Arkansas between the Missouri
River and Red rivers, as well as extending to the west. By 1760, they had increased their range to include the present Osage County.
Historically one of the most powerful Great Plains tribes, their numbers were reduced by infectious disease and warfare after encounter with
In 1825, they ceded their claim to the land in present-day Oklahoma to the United States government, which included it in a "perpetual outlet to the west given to the Cherokee Nation by the Treaty of New Echota" in 1835. This treaty was to accomplish Cherokee removal to the Indian Territory. During the American Civil War, on December 26, 1861, a band of pro-Union Creek and Seminole fought with a Confederate Army unit at the Battle of Chustenahlah on Bird Creek, near the present town of Skiatook. Generally the Five Civilized Tribes were allied with the Confederacy.
In 1870, the Osage finally prepared for removal from Kansas, after having negotiated payment for their land. They purchased 1.57 million acres (6,400 km2) of their former territory in present-day Oklahoma from the Cherokee. By owning it, they had a stronger position in relation to the US government than did other tribes. The Osage Agency was established in 1872 at Deep Ford, later renamed as Pawhuska. It was designated as the county seat when Oklahoma was admitted as a state. The other chief settlements in the 1870s were Hominy and Fairfax; each of the three was settled by a major Osage band.
In 1875 the US designated their land as the Osage Reservation. Because the tribe owned the land directly, they retained more control over their affairs than did tribes who only had rights to land held "in trust" by the United States government. This reservation became part of the Oklahoma Territory under the Oklahoma Organic Act of 1890. It became a semi-autonomous district by the Oklahoma Enabling Act of 1906, and Osage County at the time of Oklahoma Statehood in 1907. At that time, there were 2,229 registered Osage members.
