Detroit race riot of 1863

The Detroit race riot of 1863 occurred on March 6, 1863, in the city of Detroit, Michigan, during the American Civil War. At the time, the Detroit Free Press reported these events as "the bloodiest day that ever dawned upon Detroit." It began due to unrest among the working class related to racism and the military draft, which was heightened after the Emancipation Proclamation was issued by President Abraham Lincoln.
