On August 28, 1963, Martin Luther King, Jr. delivered one of his most recognized speeches in history in front of 250,000 Americans during the March on Washington.
According to Clarence B. Jones, the original speech was more political than it was historic.
After King said, “we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream,” King then went impromptu. It was reported that Mahalia Jackson, a singer, helped inspire King by saying, “Tell ‘em about the dream, Martin.”
Martin Luther King, Jr. then later delivered one of the most celebrated speeches in American history.
