Louis Alphonse, Duke of Anjou
Louis Alphonse was born in Madrid, the second son of Alfonso de Borbón, Duke of Anjou and Cádiz, and of his wife María del Carmen Martínez-Bordiú y Franco, eldest granddaughter of Francisco Franco. Alfonso was at that time the dauphin (using "Duke of Bourbon" as title of pretence) according to those who supported the claim of his father, Infante Jaime, Duke of Segovia to the French throne. On 20 March 1975, the Infante Jaime ("Henri VI" by Legitimist reckoning) died. Alfonso then asserted his claim to be both Head of the House of Bourbon and Legitimist claimant to the throne of France and the Co-Principality of Andorra. As such, he took the title "Duke of Anjou", and on 19 September 1981 gave Louis Alphonse the title Duke of Touraine.
Dauphin of France
The title was abolished by the Constitution of 1791, which made France a constitutional monarchy. Under the constitution the heir-apparent to the throne (Dauphin Louis-Charles at that time) was restyled "Prince Royal" (a "Prince of the Blood" retitled "prince français"), taking effect from the inception of the Legislative Assembly on 1 October 1791. The title was restored "in potentia" under the Bourbon Restoration of Louis XVIII, but there would not be another Dauphin until after his death. With the accession of his brother Charles X, Charles' son and heir Louis-Antoine, Duke of Angoulême automatically became Dauphin.
