Tribe (Native American)
In the United States, an Indian tribe, Native American tribe, tribal nation or similar concept is any extant or historical clan, tribe, band, nation, or other group or community of Indigenous peoples in the United States. Modern forms of these entities are often associated with land or territory of an Indian reservation. "Federally recognized Indian tribe" is a legal term of art in United States Law with a specific meaning.
An Indian tribe recognized by the United States government usually possesses Tribal sovereignty, a "dependent sovereign nation" status with the Federal Government that is similar to that of a state in some situations, and that of a nation in others. Depending on the historic circumstances of recognition, the degree of self-government and sovereignty varies somewhat from one tribal nation to another.
Legal definition in the United States
The term is defined in the United States for some federal government purposes to include only tribes that are federally recognized by the Bureau of Indian Affairs, established pursuant to the Alaska Native Claims Settlement Act [43 U.S.C. 1601 et seq.]. Such tribes, including Alaska Native village or regional or village corporations recognized as such, are known as "federally recognized tribes" and are eligible for special programs and services provided by the United States. The U.S. federal government maintains a list of ("enrolls") the members of these tribes.
