Charles IV of France
Charles IV, called the Fair (1294–1328), third son of Philip IV, ruled France and Navarre from 1322, the last king of the direct Capetian line. His first wife Blanche of Burgundy was disgraced in the Tour de Nesle affair of 1314 and their marriage was annulled. In 1324 his bid for the imperial crown failed.
That year his troops overran English-held Guyenne in the War of Saint-Sardos. Edward II then did homage and paid a fine to recover a reduced Guyenne. Charles died in 1328 leaving no son; France passed to his cousin Philip of Valois and Navarre to his niece Joan II. The succession dispute fed the Hundred Years' War.
