termination

a US federal policy adopted in 1953 that involved voiding the treaty agreements between the federal government and Native peoples, enabling the government to repossess and sell property that had been part of reservations in a process called liquidation. Terminated tribal peoples are no longer federally recognized Native peoples and have no rights to ask for federal services or assistance. Between 1954 and the 1970s, 109 tribes underwent termination. Most were federally restored between the 1970s and the 1990s.
