The French claim was reunited with that of the Isabelline Spanish line when the Carlist branch died out in 1936, although Alfonso XIII of Spain had by that time been dethroned by the Second Spanish Republic. The French and Spanish claims separated again at Alfonso's death as his eldest surviving son Infante Jaime renounced his claim to the Spanish throne due to physical disability and some years later asserted a claim to the French succession based on Legitimist principles. The present French Legitimist claimant descends from Jaime while the present king of Spain descends from his younger brother Don Juan.
