Indian Tribes Associated With This Agency

History
The Fort Leavenworth Agency was established in 1837 to replace the Northern Agency. The tribes under its jurisdiction were the Delaware, Shawnee, Kansa, and Kickapoo. Other tribes had been a part of the Northern Agency, but they were assigned to the new Osage River Agency. The agent operated from the old Northern Agency headquarters near Westport, Missouri (now part of Kansas City), but the Indians resided in what became Kansas. The agency offices were never located at Fort Leavenworth. Although the Upper Missouri Agency and the Council Bluffs Agency did operate from Fort Leavenworth at times, they never had jurisdiction over the Indians assigned to the Fort Leavenworth Agency.

In 1839, some of the Munsee and Stockbridge Indians moved onto land assigned the Delaware Indians and were assigned to this agency. The Kansa Tribe were transferred to the Osage River Agency in 1847. The Potawatomi Indians, which had been under the jurisdiction of the Pottawatomie Subagency, were assigned to Fort Leavenworth when that subagency was discontinued.

In 1851, a general reorganization of the Office of Indian Affairs took place. At that time, the Fort Leavenworth Agency was discontinued. The Potawatomi Agency became responsible for the Potawatomi and Kansas Indians. The Delaware, Shawnee, Wyandot, Munsee, and Stockbridge Indians were assigned to the Kansas Agency. And the Kickapoo were attached to the Great Nemaha Agency.
