This clip describes the purpose and impact of the March on Washington as well as the events that took place during the march. It mentions a lesser-known fact that Dr. Martin Luther King gave his I Have A Dream speech during the march not because he planned to do so, but because no one else wanted to be the last speaker at the event. Dr. King's prepared speech did not include the I Have A Dream segment, but he gave a speech about his dream at the request of Mahalia Jackson.
