Emmett Till was a 14-year-old African American boy who was brutally murdered in Mississippi in 1955, a crime that became a catalyst for the Civil Rights Movement. His death highlighted the severe racial injustices and violence faced by African Americans in the South, and it drew national attention to the need for social change. The open-casket funeral held by his mother, Mamie Till, allowed the public to see the horrific aftermath of the crime, which spurred widespread outrage and activism.
