"I Have a Dream" is the popular name given to the historic public speech by Martin Luther King, Jr., when he spoke of his desire for a future where blacks and whites would coexist harmoniously as equals. King's delivery of the speech on August 28, 1963, from the steps of the Lincoln Memorial during the March on Washington for Jobs and Freedom was a defining moment of the American Civil Rights Movement. Delivered to over 200,000 civil rights supporters, the speech is often considered to be one of the greatest and most notable speeches in history and was ranked the top American speech of the 20th century by a 1999 poll of scholars of public address."
