This man’s name may be lost to history, but he was a chief of the Sioux people – also known as the Dakota. We also know that he took part in an 1862 rebellion that included deadly attacks on white settlers around the Minnesota River. But there were horrific consequences for this insurrection. In the aftermath, 38 Native Americans were executed in a mass hanging at Mankato in the southwest of Minnesota. Photo Credit: Sepia Times/Universal Images Group via Getty Images
