On 28 August 1963 over 200,000 people took part in the historic March on Washington for Jobs and Freedom. Along with many other representatives of the civil rights movement, Martin Luther King, Jr. addressed the large crowds that evening. King's speech was the final one that day. He spoke of the unfulfilled promise of the Declaration of Independence to guarantee the inalienable rights of life, liberty, and the pursuit of happiness to all men. King also famously told the crowd about his dream: a detailed vision of what America will be like once that promise is realized. Listen to this episode to find out more about King's most memorable "I Have a Dream" speech.
