In the record

The United States made 10 treaties and agreements that name Osage as a party, from Osage at Fort Clark (1808) to Osage (Great and Little) at Canville Trading Post, Osage Nation, Kansas (1865).

C. C. Royce’s 1899 schedule records 9 cessions of land from Osage between 1808 and 1870: about 103 million acres by this atlas’s estimate, counting overlaps once. 7 of them came through treaties and agreements. The largest was Land of the Great and Little Osage in several states, ceded 1825 (area 123), about 47 million acres, ceded under Osage at St. Louis (1825).

Today, The Osage Nation carries this history, as their own pages or research records say.
