Brief history of Oklahoma before it was a state: In 1830-1862 the state we now know as Oklahoma had all its tribes relocated by India including: The Caddo tribe, The Chickasaw tribe, The Osage tribe, The Quapaw tribe, and The Wichita tribe. June 27, 1874-1875 The Red River War was the last major military war between the United States and the southern Plains Indians. The Dawes Severalty Act, was a law fought for by Senator Henry Dawes of Massachusetts that gave the federal government the power to break up Native land and give it out to tribal individuals. It was approved on February 8, 1887. Some saw this as a way to make the Indians Natives American, but in practice it resulted in a big transfer of land holdings from Natives to white settlers.
