The U.S.-Dakota War of 1862 was a conflict between the United States and the Dakota Sioux tribe in Minnesota. Tensions arose due to broken treaties, delayed payments, and food shortages, leading the Dakota to take up arms in August 1862. The war resulted in several battles and significant casualties on both sides. The conflict ended in December 1862, with the U.S. government defeating the Dakota. Following the war, many Dakota were forcibly removed from their lands, and a large number were executed or imprisoned. This war marked a significant moment in U.S. history regarding Native American relations and policies.
