Louis Alphonse de Bourbon

In 2021, Louis Alphonse attended the wedding of Grand Duke George Mikhailovich of Russia and his wife.

In 2019, he expressed public support for the Yellow vests movement in France, and later spoke at the World Congress of Families XIII, where he called for return to "Christian society".

Their fourth child, Henri, was born on 1 February 2019 in New York and was granted the title Duke of Touraine (duc de Touraine) by his father.

In March 2018, Louis Alphonse was named honorary president of the Francisco Franco National Foundation, a position held by his grandmother, Carmen Franco, 1st Duchess of Franco, until her death in December 2017. On July 15, later that year, he headed a Movement-for-Spain demonstration at the Valley of the Fallen monument, leading supporters of the late Spanish dictator, his great-grandfather Francisco Franco. They opposed the Spanish socialist government's plan to remove Franco's remains from a basilica near Madrid. He also launched a change.org petition, calling for the resignation of the Socialist Prime Minister Pedro Sánchez.

In 2017, Louis Alphonse stated that he wishes for the remains of his ancestors, including King Charles X, to remain at the Kostanjevica Monastery, after a movement reportedly began to have the King's remains moved to be buried along with other French monarchs in Basilica of St Denis.

The couple had twin sons, Louis and Alphonse, on 28 May 2010 in New York City. 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). 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. Louis and Alphonse were baptised on 5 September 2010 at St Peter's Basilica in Vatican City by Cardinal Angelo Comastri. Louis' godparents were Arancha Martínez-Bordíu (his father's maternal aunt) and Francisco D'Agostino (his mother's brother-in-law). Alphonse's godparents were Amparo Corell de Trenor, Baroness de Alacuás and Lorenzo Perales.

Louis Alphonse and María Margarita had their first child, Eugénie, on 5 March 2007, at Mount Sinai Medical Center, Miami. She was baptised at the papal nunciature in Paris in June 2007. Her godparents are Prince Charles-Emmanuel of Bourbon-Parma and his wife Constance. French Legitimists recognize her as Eugénie, Madame Royale, the style commonly attributed to the eldest unmarried daughter of a king of France (in Spain her name is Eugenia de Borbón Vargas).

Louis Alphonse's engagement to marry Venezuelan María Margarita Vargas Santaella, the daughter of the businessman Victor Vargas, was announced in November 2003. They were married civilly in Caracas on 5 November 2004 and religiously on 6 November 2004 in La Romana, Dominican Republic. None of the members of the Spanish royal family attended the wedding. Although no official reason was given, it was no secret that the then king of Spain, Juan Carlos I, did not approve his cousin's claim to the French throne, nor the fact that Louis Alphonse issued the wedding invitations styled as "Duke of Anjou".

In addition to his Spanish citizenship, Louis Alphonse acquired French nationality through his paternal grandmother, Emmanuelle de Dampierre, also a French citizen. He attended the Lycée Français de Madrid, obtaining his COU in June 1992. He studied economics at the IESE Business School. He worked several years for BNP Paribas, a French bank in Madrid.

Louis Alphonse took his primary studies at College Molière, a bilingual school, where he earned his baccalaureate. In 1991, he was admitted to CUNEF University, where he earned a master's degree in international finance. Louis is multilingual, speaking English, Spanish, and French (in addition to some Italian and German).

On 30 January 1989, his father died in a skiing accident near Vail, Colorado. Later, in 1994 Louis Alphonse received 150 million pesetas from a lawsuit against Vail Associated, which owned the ski resort where the accident occurred. Louis Alphonse was recognised by some members of the Capetian dynasty as Chef de la Maison de Bourbon (Head of the House of Bourbon) and took the title Duke of Anjou, but not his father's Spanish dukedom. He is considered the rightful pretender to the defunct French throne by adherents of the Legitimist movement.

Louis Alphonse's parents separated in 1982, and their Catholic marriage was annulled in 1986. His mother has since remarried civilly twice; he had two stepsisters Mathilda (deceased) and Marella, and a stepbrother Frederick, all born before his mother's marriage to Jean-Marie Rossi and a half-sister, Cynthia Rossi, born afterwards. On 7 February 1984, Louis Alphonse's older brother Francisco died as the result of a car crash in which Louis Alphonse was also injured, although less so than their father, who was driving the automobile. From that date Louis Alphonse was recognised as the heir apparent to his father by the Legitimists. As such, he was given the additional title Duke of Bourbon on 27 September 1984 by his father. In 1987, the Spanish government declared that titles traditionally attached to the dynasty (such as the Dukedom of Cádiz) would henceforth be borne by its members on a lifetime only basis, forestalling Louis Alphonse from inheriting that grandeeship.

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, Jaime died, and Alfonso then asserted his claim to be Head of the House of Bourbon and Legitimist claimant to the throne of France. As such, he took the title "Duke of Anjou".

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) is the head of the House of Bourbon. Members of the family formerly ruled France and other countries. According to the Legitimists, Louis Alphonse is considered the pretender to the defunct throne of France as Louis XX. With the death of his father, he has been using the title of Duke of Anjou since 1989.

Louis Alphonse considers himself the senior heir of Hugh Capet, King of the Franks (reigned 987–996). His claim to the defunct French throne is based on his descent from Louis XIV (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 this, as well as being born a Spanish citizen, makes Louis Alphonse ineligible for the throne. They also question whether he truly is the heir-male of Louis XIV, given the rumors of illegitimacy surrounding Alfonso XII (his great-great-grandfather).
