BRITTANY - DUCHY OF BRITTANY - CHARLES OF BLOIS

(1341-1364)

Charles de Blois (1319-1364) married Jeanne de Penthièvre, the daughter of Guy, brother of Jean III, last Duke of Brittany, who died in 1341. He claimed the duchy for his wife against Simon de Montfort (1341-1345), demi -brother of John III. The war began in 1341. He seized Rennes in 1342. Simon de Montfort died in 1345, his wife Jeanne de Flandre continued the fight for their son Jean IV de Montfort (1341-1399). Charles became Viscount of Limoges in 1344. After Crécy, he was captured and taken captive to England in 1347; he will only be released after the battle of Poitiers, leaving his two sons as hostages. After the Treaty of Brétigny in 1360, Jean II le Bon and Édouard III tried to reconcile the two parties at the meeting in Calais in 1362. It was a failure because of the two Joans (of Penthièvre and of Flanders). Charles was killed at the Battle of Auray on September 27, 1364.
