Bloody Sunday refers to a series of events that occurred on March 7, 1965, in Selma, Alabama, during the Civil Rights Movement. The day is best known for the brutal attack on peaceful civil rights demonstrators as they attempted to march from Selma to Montgomery to demand equal voting rights for African Americans.

Led by civil rights activists, including John Lewis and Hosea Williams, the marchers were met at the Edmund Pettus Bridge by state and local law enforcement officers who blocked their path. Without warning, the officers brutally attacked the demonstrators with billy clubs, tear gas, and rubber tubing wrapped in barbed wire. The violence was televised and widely publicized, sparking outrage across the country.

Bloody Sunday galvanized support for the Voting Rights Act of 1965, which was signed into law later that year, and ultimately led to increased federal protection of voting rights for African Americans. The courage and resilience of the marchers on Bloody Sunday are remembered as a pivotal moment in the fight for civil rights in America.
