Born at the Caserta Palace near Naples, he was the heir apparent to his father's throne at birth, as his uncle Infante Philip, Duke of Calabria was excluded from the Neapolitan and Sicilian succession due to his intellectual disability. His mother was a daughter of Empress Maria Theresa and thus sister of Marie Antoinette.
