Martin Luther King Jr. delivers his iconic "I Have a Dream" speech to a crowd of over 200,000 people in Washington D.C. He argues that (1) while emancipation gave hope for freedom, African Americans are still not truly free and continue to suffer injustice, and they have come to protest this. (2) It is time for change, the need is urgent, and they will continue the fight for justice peacefully until it is achieved. (3) Basic logic dictates that the laws of a nation founded on high principles of liberty and justice should reflect those principles for all people, yet African Americans still suffer under laws that fall short, so their wrongs must be made right.
