The Fontevraud monastic reform followed in part the lead of the highly influential and prestigious Cluny Abbey in adopting a centralized form of government, whereby in a federated structure the superiors of subsidiary houses were in effect deputies of the Abbot of Cluny, the head of the Order, and their houses were hence usually styled priories, not abbeys, governed therefore not by abbots but by priors. In the analogous case of the Order of Fontevraud, its head was the Abbess of Fontevraud, who at the death of the Order's founder, Robert of Arbrissel, in about 1117, already had under her rule 35 priories, and by the end of that century about 100, in France, Spain and England.
