The Dakota War of 1862 emerged from decades of forced land cessions and cultural displacement imposed on the eastern Dakota bands, collectively known as the Santee Sioux. All four bands of eastern Dakota had been pressured into ceding large tracts of land through a series of treaties and were confined to a narrow reservation strip twenty miles wide along the Minnesota River. U.S. Indian agents pushed the Dakota to abandon hunting traditions in favor of farming, a transition made catastrophic by a crop failure in 1861 and a subsequent harsh winter that depleted wild game populations. By summer 1862, starvation and severe hardship had created acute tensions among the Dakota, traders, and Indian agents. The immediate spark came on August 17, 1862, when four young Dakota men killed five white settlers in Acton, Minnesota, following a disagreement.
The armed conflict began in earnest on August 18, 1862, when the Dakota launched attacks against the Lower Sioux Agency and white settlements throughout the Minnesota River valley in southwest Minnesota. The war continued for five weeks, with the Dakota people responding to years of marginalization and deprivation with organized military action against American forces and settlements.
The war's aftermath proved devastating for the Dakota people. Hundreds of settlers and Dakota combatants were killed, and thousands of settlers were displaced from their homes. In the conflict's conclusion, thirty-eight Dakota men were subsequently hanged for crimes committed during the war—constituting the largest mass execution in U.S. history. Beyond the immediate casualties, the entire Dakota people faced permanent exile from their Minnesota homelands. They were forcibly removed and sent to reservations in the Dakotas and Nebraska, and the State of Minnesota confiscated and sold all remaining Dakota land within the state, erasing their territorial presence.
The American Civil War (1861–1865) was the deadliest conflict in American history, killing an estimated 620,000 to 750,000 soldiers and an unknown number of civilians. The Confederate States of America, formed by eleven seceding Southern states, faced the Union in four years of warfare across 23 states and territories. Major engagements included First and Second Bull Run, Antietam (the bloodiest single day in American history, September 17, 1862), Chancellorsville, Gettysburg (July 1–3, 1863), Vicksburg (surrendered July 4, 1863), and Sherman's March through Georgia and the Carolinas (1864–1865). President Lincoln issued the Emancipation Proclamation on January 1, 1863, transforming the war's stated purpose to include the abolition of slavery and enabling the enlistment of approximately 180,000 Black men in the United States Colored Troops. Confederate General Robert E. Lee surrendered to Ulysses S. Grant at Appomattox Court House on April 9, 1865. The war resolved the question of secession and ended American slavery, though Reconstruction would face sustained resistance in its attempt to secure civil rights for formerly enslaved people.
