Fifty years ago, on Aug. 28, 1963, hundreds of thousands of people gathered on the National Mall to take part in the March on Washington. People from all over the country traveled to the nation's capitol to rally for equal rights and to hear Martin Luther King Jr., deliver the keynote address. While the day is mostly remembered for King's "I Have A Dream" speech, the march was a watershed moment in the Civil Rights Movement that helped turned the tide of public opinion. Less than a year later, Congress passed the Civil Rights Act of 1964, which prohibited discrimination on the basis of race, color, religion, sex, or national origin. AP Marchers held hands on the national mall. Leonard Freed/Magnum King delivered his rousing "I Have a Dream" speech in front of the Lincoln Memorial on Aug. 28, 1963.
