On Aug. 28, 1963, Dr. Martin Luther King Jr. stood on the steps of the Lincoln Memorial and delivered one of American history’s landmark speeches.

King described his vision of racial tolerance and equality in his "I Have a Dream" speech, much of which was improvised. 

Today, we're marking the anniversary by tweeting the full speech in real-time, albeit 50 years later.
