Edward the Black Prince is made Duke of Cornwall, the first duchy in England.

Edward of Woodstock, known as the Black Prince, was the eldest son and heir apparent of King Edward III of England. He died before his father, and his son Richard II therefore succeeded to the throne instead. Edward was one of the most successful English commanders of the Hundred Years' War (1337–1453). He was regarded by English contemporaries as a model of chivalry and one of the greatest knights of his era, while French sources remember him for his brutality.
