Charles II (Charles the Bad), 1332–87, king of Navarre (1349–87), count of Évreux; grandson of King Louis X of France. He carried on a long feud with his father-in-law, John II, king of France, procuring the assassination (1354) of John's favorite, Charles de La Cerda, and forming an alliance with King Edward III of England. In 1356 Charles was treacherously seized by John and imprisoned, but he was rescued after the capture of John at Poitiers. He helped suppress (1358) the Jacquerie revolt and was chosen by Étienne Marcel to defend Paris against the dauphin (later King Charles V), but he betrayed this trust. Until his death he was involved in quarrels with Charles V and with Castile and in intrigues with England.
