Native American recognition in the United States

Native American recognition in the United States most often refers to the process of a tribe being recognized by the United States federal government, or to a person being granted membership to a federally recognized tribe. There are 566 federally recognized tribal governments in the United States. Non-Acknowledged Tribes are tribes which have no federal designation as sovereign entities. Federally Non-Recognized tribes refers to a subgroup of non-acknowledged tribes which had some sort of recognition by the British prior to the formation of the United States or by the United States but which were determined by the government to no longer exist as an Indian tribe or no longer meet the criteria for a nation to nation status.
