Martin Luther King Jr. delivered his most memorable speech 51 years ago.
With the Lincoln Monument as a backdrop and a packed National Mall in front of him, King delivered his I Have A Dream speech in 1963.
He said, "I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their but by the content of their character."
