Emmett Till was a young African American boy who was brutally murdered. His mother's decision to have an open-casket funeral brought attention to the violence and racism faced by African Americans, and inspired the civil rights movement.
Step-by-step explanation:
Emmett Louis Till was a 14-year-old African American boy who was brutally murdered in 1955 for allegedly whistling at a white woman. His mother, Mamie Till-Bradley, made the decision to have an open-casket funeral, allowing the public to see the horrific condition of her son's body. This decision had a significant impact on the U.S. Black freedom struggle of the 1950s-present. It brought international attention to the violence and racism faced by African Americans, galvanized civil rights activism, and inspired a generation of activists.
