Martin Luther King Jr.

"I have a dream that one day this nation will rise up and live out the true meaning of its creed: We hold these truths to be self-evident, that all men are created equal." — Martin Luther King Jr. On August 28, 1963, Martin Luther King Jr. delivered what would become a defining moment of the civil rights movement — and one of the most iconic speeches in U.S. history. King addressed the crowd of some 250,000 civil rights supporters from the steps of the Lincoln Memorial in Washington, calling for an end to racism in the United States, and civil and economic rights for all citizens.
