In this introduction to his large-scale work The Peopling of British North America, Bernard Bailyn identifies central themes in a formative passage of our history: the transatlantic transfer of people from the Old World to the North American continent that formed the basis of American society. Voyagers to the West, which covers the British migration in the years just before the American Revolution and is the first major volume in the Peopling project, is also available from Vintage Books.
