hopes for a political role. However, he could not prevent his nephew Philip the Tall from taking the regency while awaiting the birth of his brother King Louis X's posthumous son. When that son (John I of France) died after a few days, Philip took the throne as King Philip V of France. Charles was initially opposed to his nephew Philip's succession, for Philip's elder brother King Louis X had left behind a daughter, Joan of France, his only surviving child. However, Charles later switched sides and eventually backed his nephew Philip, probably realizing that Philip's precedent would bring him and his line closer to the throne. In 1324, Charles commanded with success the army of his nephew, King Charles IV of France (who succeeded his elder brother King Philip V in 1322), to take Guyenne and Flanders from King Edward II of England. He contributed, by the capture of several cities, to accelerate the peace, which was concluded between the King of France and his sister Isabella, the queen-consort of England as the wife of King Edward II. The Count of Valois died on 16 December 1325 at Nogent-le-Roi, leaving a son who would take the throne of France under the name of Philip VI and commence the branch of the Valois. Had he survived for three more years and outlived his nephew King Charles IV, Charles might have become king of France. Charles was buried in the now-demolished church of the Couvent des Jacobins in Paris – his effigy is now in the Basilica of St Denis. Marriages and children Charles was married three times. His first marriage in Aug 1290, was to Margaret, Countess of Anjou and Maine (1272–1299), daughter of King Charles II of Naples.
