In 1328 Charles IV of France died without a male heir. Queen Isabella made a claim to the throne of France on behalf of her son Edward on the grounds that he was a matrilineal grandson of Philip IV of France. However, the precedents set by Philip V's succession over his niece Joan II of Navarre and Charles IV's succession over his nieces meant that the senior grandson of Philip III in the male line, Phillip of Valois, became king. Not yet in power, Edward paid homage to Phillip as Duke of Aquitaine.
