The arguments are, on one side, that Louis XIV's younger grandson, Philip de Bourbon, Duke of Anjou renounced any future claim to the French throne when he left France to become king of Spain as Philip V in 1700 (the renunciation was ratified internationally by the Treaty of Utrecht), ostensibly leaving the Dukes of Orléans as heirs to the throne of France in the event of extinction of descendants of Louis XIV's elder grandson Louis, Duke of Burgundy, which occurred in 1883.
