Before Oklahoma was admitted to the union as a state in 1907, the Choctaw Nation was divided into three districts: Apukshunnubbee, Moshulatubbee, and Pushmataha. Each district had its own chief from 1834 to 1857; afterward, the three districts were put under the jurisdiction of one chief. The three districts were re-established in 1860, again each with their own chief, with a fourth chief to be Principal Chief of the tribe. These districts were abolished at the time of statehood, as tribal government and land claims were dissolved in order for the territory to be admitted as a state. The tribe later reorganized to re-establish its government.
