Louis Alphonse, Duke of Anjou
Their father has conferred upon them the historic French titles of, respectively, Duke of Burgundy ("duc de Bourgogne"), and Duke of Berry ("duc de Berry"). (In Spain, the twins are "Don" Luis and "Don" Alfonso de Borbón Vargas). Prince Louis, as Legitimist Dauphin of France, is expected to succeed his father as head of the French royal house, the senior Bourbon/Capetian line, in Legitimist reckoning. However, under Spanish law, and assuming Felipe VI does not in future father a son, the Spanish crown will be inherited by his elder daughter Leonor, Princess of Asturias, who will become queen regnant, and if Felipe does have a son, that son will inherit the Spanish throne regardless of the genealogical seniority of the Anjou branch. Louis and Alphonse were baptised on 5 September 2010 at St Peter's Basilica in Vatican City. Louis' godparents were Arancha Martínez-Bordíu and Francisco D'Agostino and Alphonse's were Amparo Corell de Trenor, and Lorenzo Perales.
Monarchism in France
For Orleanists, the Royal House of France is not international. The Head of the House of France is not the eldest of the Bourbons of the world, but the eldest of the national dynasty, which had been in France since the death of the Count of Chambord in 1883, the Bourbon House of Orleans. From Louis XV to Charles X, the respective Dukes of Orleans were the First Princes of the Blood, and thus the presumptive heirs in the absence of a direct heir. The nationality of the prince is the guarantor of the independence of the Crown, the strength and pride of France in Europe, that the French throne was never occupied by a foreigner, unlike most of the other monarchies and principalities of Europe.
