What year did martin Luther king Jr do his you had a dream speech?

Dr. King's speech, "I Have a Dream," was delivered to the world on August 28, 1963. The rhetoric and sentiment of the speech had been delivered to a few other small congregations prior to the March on Washington for Jobs and Freedom. Did you know that Dr. King was only one of MANY speakers at the March? Each speaker was given 4 minutes to speak, but Dr. King spoke for 16 minutes -- speaking mostly from his heart & not his notes!
