The Civil War in Minnesota primarily involved the state's role in supporting the Union during the conflict from 1861 to 1865. Minnesota contributed soldiers, with over 24,000 men enlisting to fight, and played a significant part in various battles, including the Battle of Gettysburg. The state also provided resources and supplies to the Union Army. In addition to its military contributions, Minnesota faced internal challenges, such as the Dakota War of 1862, which erupted due to tensions between the Dakota Sioux and settlers. This conflict led to significant violence and the eventual execution of 38 Dakota men, highlighting the complexities of the era in Minnesota.
