Andrzej Pleszczyński – Professor of Medieval History at the Institute of History at the University of Maria Curie-Skłodowska in Lublin. He specializes in researching Polish-Czech-German relations in the Middle Ages, treating them as confrontation of cultures of sorts. Recently, he has been interested in problems of mythologization and stereotyping in historical research – in this case, he tries to find the inertial, non-scientific influences of old, ancient-medieval concepts on modern and even contemporary historiography.
