Charles de Valois, Duc de Berry

Charles, Duke of Berry, later Duke of Normandy and then Duke of Aquitaine was a son of Charles VII, King of France. He spent most of his life in conflict with his elder brother, King Louis XI of France.

Charles was born at Tours, last child and fourth son of Charles VII and Marie of Anjou. As his elder brother, the Dauphin Louis, had repeatedly run into conflict with his father and since 1456 was living in exile at the court of Burgundy, some expected the crown to pass to Charles. When Charles VII died in 1461, however, Louis XI succeeded nonetheless.
