Tallahatchie River, near where the body washed up. #EmmettTill #Till

Emmett Till was taken from his uncle's home in the Mississippi Delta and murdered on August 28, 1955. His mutilated body was found in the Tallahatchie River two days later.

Less than six months later Rosa Parks was arrested for refusing to give up her seat on a Montgomery, Alabama, city bus. "I thought about Emmett Till," she said later, "and I could not go back."
