From the Cloister to the State examines the French order of Fontevraud, one of the largest monastic networks under female leadership in medieval and early modern Europe. Founded in 1100 and comprised of both monks and nuns, the order had grown to consist of at least seventy-eight priories by the late Middle Ages. Endowed with vast territorial possessions throughout western France, Fontevraud became one of the most powerful religious institutions in the country. However, unaware of its institutional might and economic wealth, scholars have tended to focus on Fontevraud’s seemingly unusual gender hierarchy, while bypassing inquiries on practices of abbatial authority in Fontevraud and beyond. This book reveals medieval Fontevraud as an aristocratic cloister where noble women governed. It also discusses the value of Fontevraud’s extensive network for the geopolitical ambitions of the dukes of Brittany, the counts of Bourbon-Vendôme, and, during the Wars of Religion, the kings of France. In addition to Fontevraud’s political role during the Wars of Religion, the book also examines the order’s reforms implemented by Marie de Bretagne and her successors Renée and Louise de Bourbon-Vendôme. These Bourbon abbesses centralized the order’s administration, cut the ties between priories and local aristocratic families, and successfully established the Bourbon-Vendômes as the only patrons of the vast and wealthy network. This book is essential reading for scholars and students of medieval and early modern history, as well as those interested in political history and the history of religion.
