Medieval European political and social history; history of the family; the European nobility; medieval Germany and the Holy Roman Empire
Jonathan Lyon's research and teaching focus on the political and social history of Germany, Austria, and the Holy Roman Empire in the medieval period, particularly the eleventh through thirteenth centuries. He has held fellowships from the Alexander von Humboldt Foundation (2017–18 University of Heidelberg, Germany) the Austrian Science Fund (2013–14 FWF Lise Meitner Programme #1534-G18, University of Vienna), the German Academic Exchange Service (DAAD), the J. William Fulbright Program, and the Dolores Zohrab Liebmann Foundation. His first book, Princely Brothers and Sisters: The Sibling Bond in German Politics, 1100–1250 (Cornell, 2013), won the 2017 John Nicholas Brown Prize for the best first book from the Medieval Academy of America. In it, he argues that sibling relationships played a pivotal role in shaping political dynamics both inside individual noble families and at the courts of the German kings and emperors. His current research projects include a study of the office of church advocate in medieval Germany and a general survey of the history of the medieval Holy Roman Empire. He has also published a volume of translated Latin sources entitled Noble Society: Five Lives from Twelfth-Century Germany (Manchester, 2017). He teaches courses on topics relating to medieval Central Europe and the Holy Roman Empire, premodern political cultures, and European family and gender history.
