Infante Luis, Count of Chinchón (Luis Antonio Jaime de Borbón y Farnesio; 25 July 1727 – 7 August 1785), known as the Cardinal Infante, was a Spanish infante and clergyman. He was a son of Philip V of Spain and his second wife, Elisabeth Farnese. He was cardinal deacon of the titular church of Santa Maria della Scala in Rome, archbishop of Toledo and as such primate of Spain.
He is listed in the Guinness Book of World Records as the youngest-ever cardinal.[1]
Luis Antonio Jaime de Borbón y Farnesio was born the youngest son of Philip V, King of Spain, and his second wife, Elisabeth Farnese. While barely eight years of age, Luis was created 699th Knight of the Order of the Golden Fleece in 1735 and ordained Archbishop of Toledo and Primate of Spain on 9 September 1735, and subsequently named Cardinal-Priest of the Title of the church of Santa Maria della Scala (pro hac vice) in Rome on 19 December. On 18 December 1754 he abandoned the ecclesiastical life for lack of vocation, renounced his ecclesiastical titles and dignities and assumed the title of 13th Conde de Chinchón (Count of Chinchón) granted by his brother Infante Felipe.
When his older half-brother King Ferdinand VI died without issue in 1759, Luis claimed the throne on the grounds that, he was the only surviving son of Philip V still residing in Spain (his older brothers were Charles, King of Naples and Sicily, and Philip, Duke of Parma, both reigning in Italy). However valid his claim, Luis lost the succession to his oldest brother Charles, while Charles'sthird son became Ferdinand I of the Two Sicilies.
Infante Luis was a patron of the arts and culture, and admirer of musician Luigi Boccherini, architect Ventura Rodríguez and painters Francisco de Goya, Luis Paret y Alcázar, and Charles Joseph Flipart.
King Charles III, fearful of his brother, exiled Luis far away from the Court of Madrid. In 1776 at Olias del Rey Luis contracted a morganatic marriage with an Aragonese aristocrat, María Teresa de Vallabriga.[2] This was much to the liking of Charles, because Luis now could not have children with a better claim to the throne.
Since Luis's children had been born of a morganatic marriage, they could not receive royal titles, and thus the descendants of Charles were the legitimate Spanish heirs (even though the children of Charles had been born in Naples). The couple had four children:[3]
Charles had a great deal of appreciation and devotion to his younger brother, and even during his exile, Luis was treated quite well by the Spanish court. Luis loved his brother equally as much, which is why Luis later accepted Charles as king and accepted his exile. Despite this, Luis remained bitter and saddened by the fact that he lost the opportunity to be king. Luis died disgraced and in internal exile in 1785.
