The U.S. Army built Fort Snelling between 1820 and 1825 to protect American interests in the fur trade. It tasked the fort’s troops with deterring advances by the British in Canada, enforcing boundaries between the region’s Native American nations, and preventing settler-colonists from intruding on Native American land. In these early years and until its temporary closure in 1858, Fort Snelling was a place where diverse people interacted and shaped the future state of Minnesota.
