 Edward II, King of England, as Duke of Aquitaine, owed homage to the King of France, but he had successfully avoided paying homage under Charles' older brother Louis X, and had only paid homage to Philip V under great pressure.Once Charles took up the throne, Edward attempted to avoid payment again.One of the elements in the disputes was the border province of Agenais, part of Gascony and in turn part of Aquitaine.
