Bloody Sunday refers to a violent confrontation that took place on March 7, 1965, in Selma, Alabama, during the Civil Rights Movement. Civil rights activists, led by John Lewis and Hosea Williams, organized a march from Selma to the state capital of Montgomery to protest the denial of voting rights to African Americans. As the marchers crossed the Edmund Pettus Bridge, they were attacked by state troopers with tear gas, billy clubs, and horses. The brutal assault on the peaceful protesters was captured on national television and sparked outrage across the country.

The events of Bloody Sunday galvanized support for the Voting Rights Act of 1965, which was signed into law by President Lyndon B. Johnson later that year. The Voting Rights Act aimed to overcome legal barriers that prevented African Americans from exercising their right to vote and played a crucial role in the enfranchisement of Black voters in the South.

Bloody Sunday is remembered as a pivotal moment in the Civil Rights Movement, highlighting the sacrifices and courage of activists in the fight for equality and justice.
