Bloody Sunday, which took place on March 7, 1965, in Selma, Alabama, was a pivotal moment in the Civil Rights Movement. Civil rights activists, including John Lewis and Hosea Williams, led a planned march from Selma to Montgomery to demand equal voting rights for African Americans. However, as they attempted to cross the Edmund Pettus Bridge, they were met by state troopers who brutally attacked them with batons and tear gas. The violent confrontation was captured on television and deeply shocked the nation, galvanizing support for the Civil Rights Movement.

Bloody Sunday was a turning point that ultimately led to the passage of the Voting Rights Act of 1965, which aimed to eliminate racial discrimination in voting and protect the voting rights of African Americans. The courage and resilience of the activists who were attacked on Bloody Sunday, and the public outrage that followed, played a significant role in advancing the cause of civil rights in the United States.
