Answer
The Bureau of Indian Affairs is a rarity among federal agencies. With roots reaching back to the earliest days of the republic, the BIA is almost as old as the United States itself. For most of its existence, the BIA has mirrored the public's ambivalence towards the nation's indigenous people. But, as federal policy has evolved from seeking the subjugation of American Indians and Alaska Natives into one that respects tribal self-determination, so, too, has the BIA's mission evolved into one that is based on service to and partnership with the tribes.
The BIA Mission Statement, which is based on principles embodied in federal treaties, laws and policies, and in judicial decisions, clearly describes the bureau's relationship today with the American Indian and Alaska Native people:
"The BIA's mission is to enhance the quality of life, to promote economic opportunity, and to carry out the responsibility to protect and improve the trust assets of American Indians, Indian tribes and Alaska Natives. We will accomplish this through the delivery of quality services, maintaining government-to-government relationships within the spirit of self-determination."
