African Americans Dred Scott and Harriet Robinson Scott lived at Fort Snelling in the 1830s as enslaved people. Both the Northwest Ordinance (1787) and the Missouri Compromise (1820) prohibited slavery in the area, but slavery existed there even so. In the 1840s the Scotts sued for their freedom, arguing that having lived in “free territory” made them free. The 1857 Supreme Court decision that grew out of their suit moved the U.S. closer to civil war.

The second Treaty of La Pointe (1854) ceded most Ojibwe land on the northern and western shores of Lake Superior to the U.S. government. It also established the Grand Portage and Fond du Lac reservations. In exchange, the Ojibwe received annual payments and a guarantee that they could continue to hunt and fish throughout this territory.
