After World War II, pressure in Congress mounted to reduce Washington's authority on Native American lands and liquidate the government's responsibilities to them. In 1953 the House of Representatives passed Resolution 108, proposing an end to federal services for 13 tribes deemed ready to handle their own affairs. The same year, Public Law 280 transferred jurisdiction over tribal lands to state and local governments in five states. Within a decade Congress terminated federal services to more than sixty groups despite intense opposition by Indians. Congress settled on a policy to terminate tribes as quickly as possible. Out of concern for the isolation of many Native Americans in rural areas, the federal government created relocation programs to cities to try to expand their employment opportunities. Indian policy experts hoped to expedite assimilation of Native Americans to the larger American society, which was becoming urban. In 1959, the Choctaw Termination Act was passed. Unless repealed by the federal government, the Choctaw Nation of Oklahoma would effectively be terminated as a sovereign nation as of August 25, 1970.
