Between July 30 and August 3, 1804, members of the expedition, including Meriwether Lewis and William Clark, met with Oto and Missouria tribal leaders at the Council Bluff at a point about north of present-day Omaha. Immediately south of that area, Americans built several fur trading outposts in succeeding years, including Fort Lisa in 1812; Fort Atkinson in 1819; Cabanné's Trading Post, built in 1822, and Fontenelle's Post in 1823, in what became Bellevue. There was fierce competition among fur traders until John Jacob Astor created the monopoly of the American Fur Company. The Mormons built a town called Cutler's Park in the area in 1846.

The treaty and cession involving the Omaha area occurred in 1854 when the Omaha Tribe ceded most of east-central Nebraska. Logan Fontenelle, an interpreter for the Omaha and signatory to the 1854 treaty, played an essential role in
