Luis Antonio Jaime de Borbón y Farnesio was born the youngest son of King 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.
