Nathan Leidholm received his PhD in Byzantine History from the University of Chicago in 2016. He is the author of several articles, book chapters, and reviews, as well as the monograph Elite Byzantine Kinship, ca. 950-1204: Blood, Reputation, and the Genos (Arc Humanities Press, 2019). He also serves as the co-editor of the “Family and Kinship” section of the Encyclopedia of the Global Middle Ages, a joint project with Bloomsbury and Arc Humanities Press, which appears both online and in print. His research interests include family, identity, and historical memory in Byzantium and its neighbors, both east and west, while his more recent work focuses on family and kinship among slaves in Byzantium and on the historical memory of the ancient Persian past in the medieval Mediterranean world.
