John of Montfort (Middle Breton: Yann Moñforzh, French: Jean de Montfort) (1295 – 26 September 1345,^[1] Château d'Hennebont), sometimes known as John IV of Brittany,^[a] and 6th Earl of Richmond from 1341 to his death. He was the son of Arthur II, Duke of Brittany and his second wife, Yolande de Dreux. He contested the inheritance of the Duchy of Brittany by his niece, Joan of Penthièvre, which led to the War of the Breton Succession, which in turn evolved into being part of the Hundred Years' War between England and France. John's patron in his quest was King Edward III of England.^[2] He died in 1345, 19 years before the end of the war, and the victory of his son John IV over Joan of Penthièvre and her husband, Charles of Blois.
