Bloody Sunday refers to a violent confrontation that took place on March 7, 1965, in Selma, Alabama. Civil rights activists, led by John Lewis and Hosea Williams, were marching from Selma to Montgomery to demand the right to vote for African Americans. When they attempted to cross the Edmund Pettus Bridge, they were met by state troopers and local law enforcement who brutally attacked them with tear gas, batons, and horse-mounted officers.

The images of peaceful marchers being violently assaulted shocked the nation and galvanized support for the Civil Rights Movement. The events of Bloody Sunday brought attention to the ongoing struggle for racial equality and voting rights in the United States. In response to the violence, Dr. Martin Luther King Jr. and other civil rights leaders organized a successful march from Selma to Montgomery, leading to the passage of the Voting Rights Act of 1965. Bloody Sunday remains a significant moment in Black history and the broader fight for civil rights and social justice.
