ファルネーゼ家
With the death of the last male of the House of Farnese on 30 January 1731, the grand magistry was claimed by Charles, eldest son of Elisabeth Farnese and King Philip V of Spain; Charles also inherited the duchies of Parma and Piacenza from the Farnese. After becoming king of Naples and Sicily in 1734, Charles was forced to surrender Parma to Austria in 1736, but he retained the Constantinian grand magistry. On 16 October 1759, Charles abdicated the grand magistry to his second surviving son, King Ferdinand IV and III of Naples and Sicily (from 1815 Ferdinand I of the Two Sicilies). The administration of the order was transferred from Parma to Naples in 1768.
