Dr Sophie Therese Ambler

Reader in Medieval History


I am Reader in Medieval History, Deputy Director of the Centre for War and Diplomacy, and a Research Fellow at The Ruskin. My research explores political ethics and war in the central and later Middle Ages. This includes the subject of my new book, England’s first revolution, when Simon de Montfort earl of Leicester (d.1265) led a campaign to seize power from the king and establish conciliar government; I explore the religious, intellectual and military contexts that made the revolution possible. I'm a Fellow of the Royal Historical Society, and enjoy writing for and speaking to a broad public audience, whether through talks or TV, radio and print. In 2020, I was awarded a Philip Leverhulme Prize in History.
