Blanche of France, Duchess of Orléans
Blanche of France (1 April 1328 – 8 February 1393) was the posthumous daughter of Charles IV and Joan of Évreux, born two months after her father's death; as the last direct Capetian, her birth allowed Philip VI of Valois to claim the throne. In 1345 she married Philip, Duke of Orléans; the match was childless.
While Philip was held captive in England after Poitiers in 1356, Blanche administered his lands. She died at Vincennes in 1393 and was buried at Saint-Denis.
