The Bureau of Indian Affairs (BIA) is a U.S. government agency responsible for managing relations between the federal government and Native American tribes. Established in 1824, the BIA oversees various programs related to education, land management, and economic development for tribal communities. The BIA also plays a crucial role in protecting tribal sovereignty and ensuring that treaties and agreements made with Native American tribes are honored. It works to promote self-determination and support the cultural preservation of Indigenous peoples across the United States.
