The Selma to Montgomery march was a pivotal event in the civil rights movement, held on March 7, 1965 in Selma, Alabama. The march was organized to demand voting rights for African Americans, who faced significant barriers to voting. As marchers attempted to cross the Edmund Pettus Bridge, they were met with violent opposition from state troopers and local law enforcement officers. The event sparked outrage and public support for the civil rights movement, leading to the passage of the Voting Rights Act of 1965.
