Margaret MacMillan

The Right Honourable Margaret MacMillan CC (born July 24, 1943) is a world-renowned Canadian historian, author, and academic whose masterful analyses of international relations, war, and empire have shaped modern historical scholarship. A great-granddaughter of British Prime Minister David Lloyd George, she was educated at the University of Toronto and earned her DPhil from the University of Oxford. MacMillan has held prestigious leadership roles, serving as the Provost of Trinity College at the University of Toronto and later as the Warden of St Antony’s College, University of Oxford, where she remains a professor of international history. She vaulted to global literary prominence with her 2001 masterpiece Paris 1919: Six Months That Changed the World (published in the UK as Peacemakers), which won the Samuel Johnson Prize and became the first non-fiction book to win the PEN Hessell-Tiltman Prize. Her subsequent acclaimed works, including The War That Ended Peace and her 2020 BBC Reith Lectures compilation War: How Conflict Shaped Us, have solidified her status as one of the world's premier public intellectuals.
