Peoples and Empires is the story of the great European empires -- the Roman, the Spanish, the French, the British -- and their colonies, and the back-and-forth between "us" and "them," culture and nature, civilization and barbarism, the center and the periphery. It relates the history of how conquerors justified conquest, and how colonists and colonized changed each other. It's about how we came to think about world divisions the way we do. Written by the man who has been called the world's foremost historian of human migration, Peoples and Empires will become a seminal work.
