Jean III the Good (8 March 1286 – 30 April 1341) was Duke of Brittany, from 1312 to his death and 5th Earl of Richmond from 1334 .He was the son of Arthur II, Duke of Brittany, and his first wife Marie, Viscountess of Limoges.He was strongly opposed to his father's second marriage to Queen Yolande and attempted to contest its legality.
In 1297, Jean married Isabella of Valois,eldest child of Charles, Count of Valois and his first wife Margaret of Naples. At the time of their marriage John was eleven years old and his bride five. She died childless in 1309.
In 1310, He married his second wife, Isabella of Castile.She died childless in 1328.
In 1329, Jean married his third wife Joan of Savoy.He predeceased his third wife by three years and died childless. He was unwilling to cede the Duchy of Brittany to his half-brother Jean of Montfort, son of his hated step-mother Yolande. He wished to leave the duchy to the French King Philippe VI, but his nobles objected. The marriage of his niece Joanna of Dreux to Charles of Blois gave Charles a plausible claim to the duchy, but the matter was unresolved at his death.
After his death, Jean of Montfort claimed his rights as duke of Brittany, but King Philippe VI supported the Blois faction, and the Breton War of Succession (1341–1364) was triggered. The Breton Civil War was fought between the House of Blois and the House of Montfort. It became part of the Hundred Years' War, as England supported the Montfort faction, which won, against the House of Blois, which was supported by France.
