There are currently 574 federally recognized tribal nations in the United States. As described by the National Congress of American Indians (NCAI), the oldest representative organization of tribal governments, these Native governments "have a formal nation-to-nation relationship with the US government." These governments are sovereign, meaning they have the right to self-governance, and provide many of the same services to their members as do state governments.
