'It is the aim of this essay to study the period of history from 1861 to 1872 so far as it relates to the American Negro. In effect, this tale of the dawn of Freedom is an account of that government of men called the Freedmen's Bureau, -- one of the most singular and interesting of the attempts made by a great nation to grapple with vast problems of race and social condition.' Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are.
