Emmett Till was a 14-year-old African American boy who was lynched in Mississippi in 1955 after he was accused of offending a white woman in her family's grocery store; his mother held an open-casket funeral to show the world what had been done to her son, helping spark the civil rights movement; while his death was a tragedy, it provided hope by showing that progress could be made through nonviolent action and standing up against injustice.
