Charles (1337 - 1380), son of King John II the Good became the first French heir apparent to bear the title of dauphin after the area of Dauphine was added to the royal domain in 1349. Charles became the kingdom's regent while he was still in his teens after the English captured his father at the Battle of Poitiers in 1356. As regent he dealt successfully with the revolt of the Jacquerie and the popular uprising headed by Etienne Marcel, who armed Paris against royal rule.
