Lynching in the south was not simply an act of hatred against blacks. It was an act of paranoia. Whites in the south had a belief that black men could not keep their hands off white women. The most common reason for a lynching was the accusation of rape of a white woman by a black man. Southern whites believed race mixing would lead to a weak society. They saw blacks as inferior humans that were obsessed with sex. Therefore, lynching was seen as a necessary act that was intended not only to protect the white woman of the south, but also save society from ruin.
The reason for Emmett Till's lynching has many interpretations. What we do know is that Emmett Till was black youth from Chicago who came to Mississippi in the summer of 1955 to visit his cousins for two weeks while his mother relaxed in Chicago on two weeks vacation from work as a voucher examiner in the Air Force
