At the end of the speech, King proposes that when equality and freedom are secured in the nation and around the world, all races will be able to join in the same refrain.
“When we let freedom ring, when we let it ring from every tenement and every hamlet, from every state and every city, we will be able to speed up that day when all of God’s children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old spiritual, ‘Free at last, free at last. Thank God Almighty, we are free at last.’”
A year after this speech, the Civil Rights Act was passed, which prohibited discrimination based on race, color, sex, or national origin.
