Leavenworth Site Violence (South Dakota) was a Colonial and Pre-Columbian engagement fought in South Dakota, 1450. It was a Defenders victory.
The Dakota War of 1862 arose from years of pressure on eastern Dakota bands to cede their lands through a series of treaties, which left them confined to a narrow reservation strip twenty miles wide centered on the Minnesota River valley. By 1862, the Dakota faced severe starvation and displacement from their homelands in southwest Minnesota. These dire conditions and the breach of treaty obligations created the immediate catalyst for armed resistance against both the U.S. government and white settlers who had encroached upon their territories.
On August 18, 1862, the Dakota launched coordinated attacks against the Lower Sioux Agency and white settlements throughout the Minnesota River valley. The conflict, led under the name Little Crow's War, involved several eastern bands of Dakota, collectively known as the Santee Sioux, engaging in direct combat with U.S. forces and settlers. The war maintained intensity over five weeks of sustained fighting and raids across the region.
The war resulted in hundreds of settlers killed and thousands more displaced from their homes. In the aftermath, the Dakota people faced severe punishment and permanent displacement: thirty-eight Dakota men were hanged for crimes committed during the conflict in what became the largest mass execution in U.S. history. The state of Minnesota confiscated and sold all remaining Dakota lands within its borders, and the surviving Dakota population was forcibly exiled from their homelands and relocated to reservations in the Dakotas and Nebraska, permanently severing their connection to their ancestral territories.
