Duchy of Burgundy
The Capetian House of Burgundy became extinct when Duke Philip I died in 1361, before he was able to consummate the marriage with Margaret of Dampierre, heiress of Count Louis II of Flanders. The Duchy of Burgundy was then unified with the French royal domain under the Valois king John II. Soon after, however, John's fourth son Philip the Bold received the Duchy of Burgundy as an appanage from the hands of his father.
