Francis I (in Breton Fransez I, in French François I) (11 May 1414, Vannes – 17 July 1450, Château de l'Hermine, Vannes), was Duke of Brittany, Count of Montfort and titular Earl of Richmond, from 1442 to his death. He was the son of John V, Duke of Brittany and Joan of France.

Family

Francis I's first marriage was to Yolande of Anjou, daughter of Louis II, Duke of Anjou and Yolande of Aragon; they were married at Nantes in 1431. Francis and Yolande had a son, Renaud, Count of Montfort. His son Renaud died young and his wife Yolande died in 1440.

His second marriage was to Isabel of Scotland (daughter of James I, King of Scots and Joan Beaufort); he married Isabel at the Château d'Auray on 30 October 1442. Francis and Isabel had two daughters:

• Margaret of Brittany (1443–1469, Nantes), married Francis II, Duke of Brittany
• Marie of Brittany (1444–1506), married John II, Viscount of Rohan and Count of Porhoët.

Succession

Francis I died on 17 July 1450 at the Château de l'Hermine, being only 36 years of age. Because he had no surviving male heirs at the time of his death, he was succeeded as Duke of Brittany by his younger brother, Peter II of Brittany.

During his time, the residences of the Dukes of Brittany consisted of: the Château de l'Hermine; the Château de Nantes; the Château de Clisson; and the Château de Suscinio.
