Led by the Rev. Dr. Martin Luther King, Jr., some 3,200 people began their march from Selma to Montgomery, Alabama, to protest racial violence. Earlier efforts to hold the march had failed when police attacked demonstrators and a while minister was fatally beaten by a group of Selma whites. The five-day walk ended March 26, when 20,000 people joined the marchers in front of the Alabama state Capitol in Montgomery. Soon after, Congress passed the Voting Rights Act of 1965.
