The government of Agnès of France, daughter of Saint Louis and duchess of Burgundy (c. 1260–1325).

This article focuses on Agnès de France (1260–1325), the youngest daughter of Saint Louis and Marguerite de Provence, and her significant political role as duchess and regent of Burgundy in the late thirteenth and early fourteenth centuries. Through her positions as royal daughter, wife of Duke Robert II of Burgundy, widow, mother, and grandmother, Agnès exercised considerable authority in governing the duchy, managing its administration, arranging strategic marriages, and defending her family's dynastic interests, notably during the minority of her sons and the royal succession crisis of 1316. Her governance was marked by active political decisions, including the expulsion of Jews from Burgundy in 1306, and she leveraged her royal lineage—especially after the canonization of Saint Louis—to legitimize and strengthen her power. Agnès’ career illustrates the complex ways Capetian royal women could wield influence within medieval aristocratic and familial networks, balancing gendered constraints with dynastic authority.
