Those Legitimists who did not accept the Orléanist line as the successors of Chambord argued that the renunciation of the French throne by Philip V of Spain, second grandson of Louis XIV, was invalid and that in 1883 (when Chambord died childless) the throne passed by right to Philip V's male heirs. In 1883, the senior male of the Spanish branch of Bourbons, Carlos de Borbón, Count of Molina, had lost Spain's throne in favor of the non-Salic heiress Isabella II and his lineage became known as the Carlist pretenders in Spain.
