In 1862, a fierce battle, formerly known as the Sioux Uprising, broke out between Minnesota's white European settlers and its Dakota Indian population. By the end of the year, hundreds of settlers and Dakota were dead, thousands of Dakota were imprisoned and exiled, and 38 Dakota were hanged. The story of the violent chapter in America's history, its causes and aftermath is told through diaries, old photographs, sketchbooks, newspaper archives, trial transcripts and oral histories.
