Louis Alphonse de Bourbon, Duke of Anjou (, ; born 25 April 1974 in Madrid) is a member of the Royal House of Bourbon, and one of the current pretenders to the defunct French throne as Louis XX.
Capetian dynasty
Historians in the 19th century (see House of France) came to apply the name "Capetian" to both the ruling house of France and to the wider-spread male-line descendants of Hugh Capet. It was not a contemporary practice. The name "Capet" has also been used as a surname for French royalty, particularly but not exclusively those of the House of Capet. One notable use was during the French Revolution, when the dethroned King Louis XVI (a member of the House of Bourbon and a direct male-line descendant of Hugh Capet) and Queen Marie Antoinette (a member of the House of Habsburg-Lorraine) were referred to as "Louis and Antoinette Capet" (the queen being addressed as "the Widow Capet" after the execution of her husband).
