Dr Sophie Therese Ambler

Lecturer in Later Medieval British and European History


I'm a historian of the Middle Ages, focusing on the thirteenth to fifteenth centuries, largely in England and France but also looking to the Iberian Peninsula, Italy and the Holy Land, with broad interests in radicalism and war. I joined Lancaster in 2017, and teach an undergraduate course on the Crusades and a co-taught MA course on non-textual sources, as well as contributing to several other modules. Previously I was at the University of East Anglia, where I was fortunate to be a researcher on the AHRC's Magna Carta Project, which produced a number of new and exciting discoveries about the Charter. From 2012-13 I was a researcher for the AHRC's Breaking of Britain project, which explored the period leading up to the Wars of Independence. I undertook my PhD at King's College London with joint supervision at University College London, and in my fourth year was Thornley Fellow at the Institute of Historical Research. I'm a Fellow of the Royal Historical Society and secretary of the Pipe Roll Society, and enjoy writing for and speaking to a broader public audience, whether through talks or TV, radio and print.
