Colonial Williamsburg in Williamsburg, Virginia, is the world’s largest living history museum—the restored 18th-century capital city of Britain’s largest, wealthiest, and most populous outpost of empire in the New World. Here we interpret the origins of the idea of America, conceived decades before the American Revolution. The Colonial Williamsburg story, “Becoming Americans,” tells how diverse peoples, having different and sometimes conflicting ambitions, evolved into a society that valued liberty and equality. Americans cherish these values as a birthright, even when their promise remains unfulfilled.
