Blanche of Brittany

Blanche of Brittany (c. 1270/1271 – 1328) was the daughter of Duke John II of Brittany and Beatrice of England, granddaughter of Henry III. In 1281 she married Philip of Artois, the Artois heir. Her seven children included Margaret, Robert III of Artois, Joan and Marie.

Philip died in 1298 of wounds received at Furnes, and Artois went to his sister Mahaut rather than to Blanche's son Robert. Her long widowhood was spent at the French court, and she died at Vincennes in 1328.
