Indian Territory was originally founded on the principle that the land would be owned collectively by all tribal members. As the white settlers pushed for even more land the government began to make treaties with the Indians that began a process of allotment whereby each individual member of a tribe would be given their own lot of land. What was left would be sold to white settlers. Once the Natives had their own land they could do with it as they pleased. The Natives in Indian Territory attempted to resist allotment but in 1897 the Seminoles agreed to the Dawes Allotment Act in order to keep at least some of their land from being taken from them. The other Nations of the Five Civilized tribes soon followed suit. Osage land, however, was not allotted until 1906. All the Osage land was divided equally among the tribal members.
Drawing for the Big Pasture lands containing a half million acres, was sold in 160 acre tracts to the highest bidders.
