The voting rights march from Selma to Montgomery, Alabama, was a defining moment in the modern civil rights movement. Televised footage of the brutal attack on demonstrators by state troopers during the first attempted march dramatically shifted much of the public opinion in favor of the protesters. President Lyndon B. Johnson, who had also witnessed coverage of the events of “Bloody Sunday,” publicly backed their cause. The day after one of the demonstrators in the second march attempt was clubbed to death by Ku Klux Klan members, President Johnson introduced what would become the Voting Rights Act. Finally on March 16, 1965, with the protection of the National Guard and the support of people around the world, over 3,000 Americans crossed the Edmund Pettus Bridge out of Selma.
