Royal Deputation

Grand Prefect

  • H.R.H. Princess Beatrice of Bourbon Two SiciliesHer Royal Highness Princess Beatrice of Bourbon Two Sicilies, sister of the Grand Master, has been a Dame Grand Cross of Justice since December 1978 by motu proprio of her august parent H.R.H. Prince Ferdinando, of revered memory. As part of the renewal of the Government of the Dynastic Orders, H.R.H. the Grand Master appointed her as Grand Chancellor on 13th June 2014 by Motu Proprio, and then on 14th May as Grand Prefect.
    “The Grand Prefect is the highest authority of the Order after the Grand Master and mormaly represents the latter in the event of absence.” (Article I of Chapter VII of the Order’s Statutes).
    For the first time in the history of the Constantinian Order and of the Dynastic Orders of the House of Bourbon Two Sicilies, a woman takes up a governmental office within the Grand Magistry: a sign of renewal and forward-looking intuition of H.R.H. the Grand Master both in terms of a greater involvement of the members of the Royal Family and in terms of a fitting adjustment to the customs of modern times which rightly recognize the important role of women in society.
    Speaking as Grand Chancellor at the first Collegial Meeting (Rome, 12-14 September 2014), H.R.H. Princess Beatrice in fact stated: “As a woman this nomination gives me the opportunity to pay tribute to all the women of our Family who have always shown great courage and who, discreetly, have been at the origin of many important decisions and initiatives”. The prerogatives of the Grand Chancellor also include the coordination of the Delegates who preside over the Delegations of Knights and Dames in Italy and in the rest of the world, and for this reason H.R.H. Princess Beatrice, in the same speech, reiterated as follows: “Concerning the admission of new members to the Order, there is need for the Delegates to assume greater responsibility: you
    must only introduce people with whom you are
    personally well acquainted and with whom you
    socialize, involving the candidates in the life and activities of the Delegation for a reasonable length of time before they can aspire to be introduced as potential members of the Order. You must in advance understand the reasons which spur the candidate to wish to approach the Order and make sure that they are compatible with the finalities set down in our Statutes. Together with the other High Dignitaries it has been decided that the Knights
    must necessarily be resident in the Delegation into which they are introduced. To be a Delegate of the Order is certainly an honour, but it is equally a duty which requires not only an attachment to the Sacred Constantinian Military Order, which you certainly do not lack, but also commitment and often sacrifice. Therefore please evaluate through a fair and honest analysis your willingness to fulfil not only your duties as Knights but also that of wanting and being able to assume your own duties as a Delegate”. H.R.H. Princess Beatrice who, together with H.R.H. the Duchess of Castro, is the inspiration behind the humanitarian and welfare assistance of the Constantinian Order, is the mother of His Imperial Highness the Prince Napoleon,Head of the Imperial House of France and Vice
    President of the Royal Deputation.
