Charles IV of France
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.
