In recent decades historians have documented the nature and impact of religious violence within French Catholicism during the French Wars of Religion (1562-1629). My dissertation introduces the question of religious nonviolence within French Catholicism in this era by examining the religiosity practiced and promoted by Francois de Sales (1567-1622). By interpreting the words, actions, and impact of this clergyman across three different contexts - the mission field of the Chablais, in lay spiritual counseling, and in the Order of the Visitation- this research presents a fresh perspective on the nature of Catholicism in early modern France and an important historical case study of the possibilities and limits of moderation in a society reeling from religious extremism.
