The first federal Indian Reservation is created by the United States.

An Indian reservation in the United States is an area of land held and governed by a Native American tribal nation officially recognized by the U.S. federal government. The reservation's government is autonomous but subject to regulations passed by the United States Congress, and is administered by the United States Bureau of Indian Affairs. It is not subject however, to a state or local government of the U.S. state in which it is located. Some of the country's 574 federally recognized tribes govern more than one of the 326 Indian reservations in the United States, while some share reservations, and others have no reservation at all. Historical piecemeal land allocations under the Dawes Act facilitated sales to non–Native Americans, resulting in some reservations becoming severely fragmented, with pieces of tribal and privately held land being treated as separate enclaves. This intersection of private and public real estate creates significant administrative, political, and legal difficulties.
