Bloody Sunday, also known as the Selma to Montgomery marches, was a series of civil rights demonstrations that occurred in 1965 in Selma, Alabama. The first march took place on March 7, and was led by civil rights activists including John Lewis and Hosea Williams. The marchers were attempting to walk from Selma to Montgomery to demand voting rights for African Americans.

As the marchers crossed the Edmund Pettus Bridge in Selma, they were met by Alabama state troopers who violently attacked them with billy clubs, tear gas, and horses. The brutal assault was captured on film and broadcasted on national television, shocking the nation and galvanizing support for the Civil Rights Movement.

The events of Bloody Sunday ultimately led to the passage of the Voting Rights Act of 1965, which prohibited racial discrimination in voting and aimed to ensure equal access to the ballot box for all Americans. Bloody Sunday remains a key moment in Black history and a symbol of the ongoing struggle for civil rights and racial justice.
