was Dr. King's purpose in his i have a dream speech to persuade people that nonviolent tactics can help them accomplish their goals

The 1963 March on Washington reaffirmed for some, enlightened others, and promised again that the rights of all Americans was the underlying purpose of Dr. Martin Luther King's speech. The reason Dr. King's 'I Have A Dream' speech is so moving is because he spoke what he BELIEVED was the truth regarding racial injustice in the U.S. The 1963 speech took on the sound of a higher power. Dr. King's words stopped people in their tracksand forced them to recognize the plight of others. The speech was given at the right time in the right place, which resulted in a heightened sense of awareness among many Americans. Hope this gives you some needed context.
