On March 21, 1965, Martin Luther King, Jr. began his third march from Selma to Montgomery, Alabama to protest racial discrimination in the Jim Crow South. By March 25, over 25,000 people led by Dr. King reached Montgomery, Alabama. Specifically, the march called attention to the suppression of African-American voting rights and a police assault on a civil rights demonstration three weeks prior. Five months later, in August 1965, Congress passed the Voting Rights Act. Read a history of the march from Selma to Montgomery.

March 21 is the International Day for the Elimination of Racial Discrimination.
