The United States in the 1950s and 60s was a troubled place. Black people were angry, because they did not have the same rights as whites. It was a time of angry words, of marches, of protests, a time of bombs and killings. But above the angry noise came the voice of one man — a man of peace. I have a dream, said Martin Luther King, and it was a dream of blacks and whites living together in peace and freedom. This is the story of an extraordinary man, who changed American history in his short life.
