Louis Alphonse de Bourbon (Spanish: Luis Alfonso Gonzalo Víctor Manuel Marco de Borbón y Martínez-Bordiú, French: Louis Alphonse Gonzalve Victor Emmanuel Marc de Bourbon; born 25 April 1974, in Madrid is the head of the House of Bourbon by primogeniture. The Bourbons are the royal family of Spain. Members of the family formerly ruled France and other countries. As a pretender to the French throne, he is styled Louis XX and Duke of Anjou.
Louis Alphonse considers himself the senior heir of King Hugh Capet of France (r. 987 to 996). His claim to the French throne is based on his descent from Louis XIV of France (r. 1643-1715) through his grandson Philip V of Spain. Philip renounced his claim to the French throne under the Treaty of Utrecht in 1713. The rival Orleanist pretenders argue that as a Spanish citizen Louis Alphonse is ineligible for the throne.
Louis Alphonse is patrilineally the senior great-grandson of King Alfonso XIII of Spain. However, his grandfather Infante Jaime, Duke of Segovia, renounced his rights to the Spanish throne for himself and his descendants owing to his deafness (a renunciation disputed by legitimists). The crown of Spain has descended to his second cousin, King Felipe VI of Spain. Through his mother, he is also a great-grandson of Spain’s caudillo (dictator), General Francisco Franco and through his father, a great-great-great-grandson of Queen Victoria of the United Kingdom.
