I studied for a BA in Ancient and Medieval History at Cardiff University, and then undertook doctoral research on the early history of the ‘crusader’ principality of Antioch at Royal Holloway, University of London.

I then taught at St Andrews and the University of Reading, before joining Queen Mary in 1999.


I am a medieval historian specialising in the study of the crusades, knighthood and chivalry, and medieval violence. My major publications include The Crusades – The War for the Holy Land (2010), which so far has been translated into eight different languages, and a biography of the influential medieval knight William Marshal titled The Greatest Knight (2015). My current research explores whether the violence enacted during the crusades was more extreme than that witnessed in other forms of medieval warfare.
