Adaptation. . , The Chickasaw lived in an area of Indian Territory bordered on the east by the Choctaw and on the west by the Comanche and other tribes. The United States government admitted that it could not protect the Chickasaw from the raiding by the neighboring western tribes and they fell victim to man livestock raids. To compound matters, the Texans to the south drove Native Americans out of that territory and onto Chickasaw land., By the 1850s the Chickasaw were established in their new home. The Treaty of 1855 recognized the Chickasaw as a sovereign nation and formally delineated between the Choctaw and Chickasaw Territory. The Chickasaw adopted a constitution modeled after the United States Constitution that created the position of the governor (formally the traditional tribal chief), a legislature (formerly) the tribal council), and a judiciary., The Chickasaw maintained their identity and asserted their rights as an independent nation within the United States through the remainder of the nineteenth century.
