[1] Blanche d'Évreux was intended to become the bride of John, Duke of Normandy, heir of the throne of France — whose first wife had just died of the Black Death— but eventually married his father, King Philip.

On 2 October 1380, she attended the proclamation of the end of the regency of the young sovereign at the Palais de la Cité,[18] and on 18 July 1385, she welcomed his new wife Isabeau of Bavaria at Creil.
