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.
List of French monarchs
This article lists all rulers to have held the title "King of the Franks", "King of France", "King of the French" or "Emperor of the French". For other Frankish monarchs, see List of Frankish kings. 
In addition to the monarchs listed below, the Kings of England and Great Britain from 1340–60, 1369-1420, and 1422–1801 also claimed the title of King of France. For a short time, this had some basis in factunder the terms of the 1420 Treaty of Troyes, Charles VI had recognized his son-in-law Henry V of England as regent and heir. Henry V predeceased Charles VI and so Henry V's son, Henry VI, succeeded his grandfather Charles VI as King of France. Most of Northern France was under English control until 1435, but by 1453, the English had been expelled from all of France save Calais (and the Channel Islands), and Calais itself fell in 1558. Nevertheless, English and then British monarchs continued to claim the title for themselves until the creation of the United Kingdom in 1801.
