knighthood
In 1900, his younger brother, Prince Charles, renounced all his dynastic rights over the Throne of the Two Sicilies and therefore the Grand Magister of the Orders of knighthood of the Royal Family knighthood for himself and all his descendants: this was necessary so that he could become Infant of Spain by marrying the Infant Maria Mercedes of Bourbon, daughter of King Alfonso XII.
In this site, we provide all necessary details and explanations under the heading "The Sacred Military Constantinian Order of St. George and the Royal Family of the Bourbon Two Sicilies knighthood ", where we explain the historical, dynastic and legal reasons by which Charles's heirs knighthood - because they are members of the Royal Spanish knighthood family and therefore no longer memeber of the Royal Family of the Two Sicilies knighthood - have no right to be or use the title of Head of the Royal Family of the Two Sicilies knighthood and can no more be the holders of the Grand Magistry of the Orders of Knighthood linked to the Royal Family knighthood.
On 28 May 1934, the Earl of Caserta died and His Royal Highness Prince Ferdinand Pio of Bourbon Two Sicilies (de jure, Ferdinand III) became the Head of the Royal Family and claimed his dynastic rights and issued new Statutes for the Constantinian Order of St. George knighthood. Born in 1869, he lived in Bavaria and had a life of sincere Christian piety; without giving up his rights, he reconciled with the Savoy family. He donated part of the Bourbon Archive to the Italian State. He died heirless on 7 January 1960 (his only son had died at the age of 13 in 1914), and therefore all his dynastic rights went to his brother, His Royal Highness Prince Ranieri of Bourbon Two Sicilies knighthood (since, as we said, Charles renounced all his dynastic rights for himself and all his descendants to become Infant of Spain knighthood), universally known as Head of the Royal Family and Grand Master of the Orders of knighthood of the Royal Family; Ranieri took the tile of Duke of Castro, which is due to the Head of the Royal family (knighthood). Born in Cannes on 3 December 1883, he too served in the Royal Spanish Army; in 1923 he married his cousin Countess Carolina Zamoyska and Bourbon Two Sicilies; during his life he generously supported many charity associations; in 1962 he attended the transfer of the corpses of Royal Family members to the Church of Santa Chiara in Naples knighthood .He died on 13 January 1973 in his house, Saint-Sauver castle, but already in 1966 he had passed all his functions to his son Ferdinand, present Duke of Castro, Head of the Royal Family of the Bourbon of the Two Sicilies and Grand Master of the Orders of knighthood of the Royal Family. Present Head of the Royal Family of the Bourbon Two Sicilies knighthood is His Royal Highness Prince Ferdinand of Bourbon Two Sicilies knighthood , (de jure, Ferdinand IV), Duke of Castro, Grand Master of the Illustrious Order of San Gennaro, Grand Master of the Sacred Military Constantinian Order of St. George, Grand Master of the Royal Order of Francis I, Grand Master of the Royal Military Order of St. George and Reunion, Grand Master of the Royal Order of St. Ferdinand and Merit.
