On Dec. 26, 1862, 38 Dakota Indians were executed by the U.S. government during the U.S. Dakota War of 1862 (also known as the Sioux Uprising, Dakota Uprising).
Jon Wiener provides some background in ‘Largest Mass Execution in US History: 150 Years Ago Today‘ in The Nation,
Minnesota was a new frontier state in 1862, where white settlers were pushing out the Dakota Indians—also called the Sioux. A series of broken peace treaties culminated in the failure of the United States that summer to deliver promised food and supplies to the Indians, partial payment for their giving up their lands to whites.
The Indians responded in the Santee Sioux uprising, killing 490 white settlers. The Dakota were executed for their role in the war of self-defense. As Wiener notes,
[President Abraham] Lincoln’s treatment of defeated Indian rebels against the United States stood in sharp contrast to his treatment of Confederate rebels. He never ordered the executions of any Confederate officials or generals after the Civil War, even though they killed more than 400,000 Union soldiers.
Growing up in Mankato, Minnesota, John Biewen says, nobody ever talked about the most important historical event ever to happen there: in 1862, it was the site of the largest mass execution in U.S. history. Thirty-eight Dakota Indians were hanged after a war with white settlers. John went back to Minnesota to figure out what really happened 150 years ago, and why Minnesotans didn’t talk about it much after.
