Margaret I, Countess of Burgundy

Margaret I (1310 – 9 May 1382) was a Capetian princess, a daughter of King Philip V of France and Joan II of Burgundy. In 1320 she married Louis I of Flanders, binding his county to the French crown, and when Louis fell at Crécy in 1346 she served as regent of Flanders for her son Louis II.

After Duke Philip I of Burgundy died childless in 1361, Margaret inherited Artois and the county of Burgundy and ruled them suo jure. She promoted the 1369 marriage of her granddaughter Margaret III to Philip the Bold.
