Luis was born in the city of Seville in Spain. He was the youngest child of the king King and queen of Spain. He was given the name Luis in honour of his French great-grandfather Louis XIV. From a young age his father showered various religious titles upon his youngest son, even creating him a "Primate of Spain". Giving him the rank of an Archbishop while barely eight years old. He was also an Infante of Spain by birth being the child of a reigning Spanish monarch giving him the use of "Royal Highness" from birth. Despite his parents decisions the young Luis abandoned his religious rank due to a lack of interest in his charges on 18 December 1754. He was given the title of Count of Chinchón by which he is known. The title was eventually inherited by his daughter Maria Teresa and was given to him by his older brother The Infante Felipe.
