Historic Fort Snelling

Fort Snelling is a former military fortification and National Historic Landmark in the U.S. state of Minnesota on the bluffs overlooking the confluence of the Minnesota and Mississippi Rivers. The military site was initially named Fort Saint Anthony, but it was renamed Fort Snelling once its construction was completed in 1825.

Before the American Civil War, the U.S. Army supported slavery at the fort by allowing its soldiers to bring their personal enslaved people. These included African Americans Dred Scott and Harriet Robinson Scott, who lived at the fort in the 1830s. In the 1840s, the Scotts sued for their freedom, arguing that having lived in "free territory" made them free, leading to the landmark United States Supreme Court case Dred Scott v. Sandford. Slavery ended at the fort just before Minnesota statehood in 1858.
