Rutger Kramer has studied French and English at the Zuyd University for Applied Sciences, and History at Utrecht University. After finishing his M.Phil. thesis on the use of the Bible in early medieval Breton hagiography, he went to the Freie Universität Berlin to write his PhD thesis on Carolingian rulership and monastic reforms in the eighth and ninth centuries, as part of the DFG/ANR project Hludowicus: Die Produktivität einer Krise. His thesis was subsequently turned into a monograph for Amsterdam University Press: Rethinking Authority in the Carolingian Empire: Ideals and Expectations during the Reign of Louis the Pious (813-828). Meanwhile, in Vienna he has worked as part of the VISCOM Project Coordination Team, before moving on to a full-time research post within the team working on Early Medieval Europe. Rutger's research interests currently include early medieval monasticism, Carolingian hagiographical and other narrative sources, medieval Bretagne and Aquitaine and, more generally, the interdependence between overarching ideologies and individual communities, as well as the persistence of "medieval" modes of thinking in modern media and politics.
