Christian Raffensperger specializes in medieval and Eastern European history. He offers expert commentary on the Ukraine War and the historical and political dynamics shaping the region, and is available for lectures, podcasts, interviews, and panel discussions. His academic goal has remained the same since the completion of his Ph.D. at the University of Chicago —the integration of the medieval polity of Rus into the larger medieval European world, a theme that is present throughout his research and teaching.
