I’m a professor of history at the University of Toronto, and Emeritus Professor of International History at Oxford.

My research and my writing are mainly on the international history of the 19th and 20th centuries. I have written books about the origins of the First World War, and then about the Paris Peace Conference, which tried to wind up that war. My most recent book is called War: How Conflict Shaped Us.
