Letters Received by the Office of Indian Affairs, 1824-1880

The Office of Indian Affairs was established in 1824 under the War Department. It was transferred to the Department of the Interior when that department was created in 1849. In 1947, the name was changed to the Bureau of Indian Affairs.

Prior to 1824, most of the Indian affairs in the United States was directly supervised by the Secretary of War. The major exception was that government trading posts, or factories, were under the supervision of the Office of Indian Trade.

Letters received by the Commissioner's Office in the Office of Indian Affairs for the years 1824 thru 1880 have been arranged primarily by the names of the field units of that office. The two main field offices in existence during those years were the superintendencies and the agencies.
