One of the earliest U.S. military posts west of the Missouri River, Fort Atkinson was established in 1820 on the recommendation of the Lewis and Clark Expedition, and served as an important outpost for fur trade, river traffic, and American Indian relations. It was active until 1827 and located in what would become Fort Calhoun, Nebraska.
