I'm Gregory Leighton

PhD, Medieval History.

I earned my doctorate in History and Welsh History at Cardiff University in the summer of 2018. My thesis  primarily focused the military orders, specifically the Order of the Teutonic Knights (founded 1190) in the medieval Baltic region (present-day Latvia, Estonia, Poland, Lithuania, and parts of Russia). The spirituality of the military orders as religious institutions, the evolution and origins of the concept of 'crusading', and the application of this concept to the last pagan frontier of medieval Europe, fascinate me.  Religious life in the medieval Baltic 'off of the battlefield' is a further topic I have come to be very intrigued by, namely the use of pilgrimage shrines and relics by the local Christian population in the region. Translating sources and providing useful learning tools are also important goals of mine, and this is the current project that I am working on at the moment.
