Philip V of France
After the death of his nephew, Philip immediately had himself crowned at Reims. However, his legitimacy was challenged by the party of Louis X's daughter Joan. Philip successfully contested her claims for a number of reasons, including her youth, doubts regarding her paternity (her mother was involved in the Tour de Nesle Affair), and the Estates General's determination that women should be excluded from the line of succession to the French throne. The succession of Philip, instead of Joan, set the precedent for the French royal succession that would be known as the Salic law.
