Fort Osage (also known as Fort Clark or Fort Sibley) was an early 19th-century factory trading post system run by the United States Government, on the American frontier being located in present-day Sibley, Missouri. The Treaty of Fort Clark was signed with certain members of the Osage Nation in 1808 calling for the creation of Fort Osage. It was one of three forts established by the U.S. Army to establish control over the newly acquired Louisiana Purchase territories. Fort Madison in SE Iowa was built to control trade and pacify Native Americans in the Upper Mississippi River region. Fort Belle Fontaine near St. Louis controlled the mouth of the Missouri. The fort ceased operations in the 1820s as the Osage in subsequent treaties ceded the rest of their land in Missouri. A replica of the fort was rebuilt on the site between 1948 and 1961. The Fort Osage school district (including Fort Osage High School), which serves northeast Independence and the surrounding area, was named after it.
