John Eldevik received his Ph.D from UCLA and taught at UCLA and Pomona College before coming to Hamilton in 2010. He also holds the Licence in Mediaeval Studies (2004) from the Pontifical Institute of Mediaeval Studies in Toronto. His primary research and teaching interests are in medieval social and religious history, particularly the role of the bishop in the early Middle Ages, as well as the Crusades and the history of political and religious dissent. His first book, Episcopal Lordship and Ecclesiastical Reform in the German Empire, 950-1150 was recently published by Cambridge University Press and examines how medieval bishops used the collection of ecclesiastical tithes (taxes) to foster important social and political relationships in their dioceses. Eldevik is currently working on a study of the manuscript transmission of texts on the Crusades and Islam in medieval Bavaria.
