In this book Niall Ferguson argues that the British Empire should be regarded not merely as vanished Victoriana but as the very cradle of modernity. Nearly all the key features of the twenty-first-century world can be traced back to the extraordinary expansion of Britain's economy, population, and culture from the seventeenth century until the mid-twentieth--economic globalization, the communications revolution, the racial make-up of North America, the notion of humanitarianism, the nature of democracy. Ferguson shows that far from being a subject for nostalgia, the story of the Empire contains lessons for the world today--in particular for the United States as it stands on the brink of a new kind of imperial power based once again on economic and military supremacy.
