King delivered a now-famous call for justice in 1963.
On Aug. 28, 1963, more than 200,000 Americans marched in the nation's capital, calling for the government to end social, economic and political inequality between blacks and whites. The Rev. Martin Luther King Jr.'s "I Have a Dream" speech put a dramatic exclamation point on the day's events. Nearly 50 years after his speech, King’s dream is being realized.
