Since 1975, when the U.S. government adopted a policy of self-determination for American Indian nations, a large number of the 562 federally recognized nations have seized the opportunity to govern themselves and determine their own economic, political, and cultural futures. As a first and crucial step in this process, many nations are revising constitutions originally developed by the U.S. government to create governmental structures more attuned to native people's unique cultural and political values.
