Elena Maria Vidal has an article about the Comte de Provence, a treacherous younger brother of King Louis XVI of France. Unfortunately, it reminds me of Prince Charles of Belgium, who also harbored envy and hatred of his older brother and sovereign, King Leopold III. During the King's exile in Austria, after World War II, Prince Charles, then Regent of Belgium, and the Prime Minister, Achille van Acker, even tried to persuade Princess Lilian to desert Leopold, promising her lavish sums and luxurious privileges if she abandoned her husband and returned to Belgium with her step-son, the heir to the throne, young Prince Baudouin. (Needless to say, Lilian indignantly rejected the offer, once again giving the lie to the black legend that she was a gold-digger).
The attempt to suborn the Princess was the sordid culmination of life-long tensions between the two surviving sons of King Albert I. The episode, mentioned by Leopold in Pour l'Histoire: sur quelques épisodes de mon règne (2001) and by Lilian in Un couple dans la tempête: le destin malheureux de Léopold III de Belgique et de la princesse Lilian (2004), had also been discussed, even earlier, by Jacqueline de Peyrebrune, a mistress of Prince Charles, who claimed to have secretly married him, in her Carnets intimes: le jardin secret du prince Charles de Belgique (1993). Nevertheless, upon the publication of Pour l'Histoire, the historian Jean Stengers, an old opponent of Leopold III, accused him of fabricating the scandalous story. Further evidence, however, subsequently emerged from the King's private notes and correspondence with his brother, vindicating his veracity in this sad affair.
Throughout the Royal Question, Charles collaborated with Leopold's opponents. His regency lent the trappings of legitimacy to their revolutionary efforts to prolong the King's incapacity to reign after his liberation from German captivity. During this period, Charles made little effort to defend Leopold from the false accusations of cowardice and treason on the part of British, French and Belgian authorities. Many try to justify Charles' behavior, arguing that his compliance with the government and the Allies protected the peace of the country and enabled the monarchy to survive. Perhaps he did act, at times, out of patriotism, but why connive at such a base proposition as attempting to suborn Princess Lilian? Such an action reflects malice. As a result, I suspect that the Prince's motives throughout his regency were far from pure.
