Writing in The New York Review of Books, Robert Skidelsky praised Ferguson: "Taken together, Ferguson's two volumes are a stupendous achievement, a triumph of historical research and imagination. No serious historian can write about the connection between the politics, diplomacy, and economics of the nineteenth century in the same way again. And, as any good work of history should do, it constantly prompts us to ask questions about our own age, when once again we have embarked on the grand experiment of a world economy without a world government."
