Lesdiguières

François de Bonne, Duke of Lesdiguières (1543–1626), was one of the most prominent military figures in Dauphiné. During the Wars of Religion, he emerged as the main Protestant leader of the province. His authority helps explain the resistance and longevity of local Protestantism in Mizoën and the Oisans. He had the church of La Grave fortified, transformed into a defensive point, illustrating the military and religious role of these mountain villages.
