Happy 87th birthday to Princess Irene of the Netherlands! 🎂
Born Irene Emma Elisabeth on August 5, 1939, she is the second daughter of Queen Juliana of the Netherlands and Prince Bernhard of Lippe-Biesterfeld. She is the younger sister of the former Queen Beatrix and maternal aunt of King Willem-Alexander of the Netherlands.
Princess Irene created a controversy in 1963 when she secretly converted from Protestantism to Roman Catholicism and married a Catholic prince, Carlos Hugo, Duke of Bourbon-Parma, in 1964.
Prince Carlos Hugo (1930-2010) was the eldest son of Carlist claimant to the Spanish throne: Xavier, Duke of Parma, the Head of the House of Bourbon-Parma.
IWhen news leaked out that she was engaged to Prince Carlos Hugo, it provoked a Protestant outcry and a constitutional crisis in the Netherlands.
Although Dutch law did not forbid a Catholic to reign over the Netherlands, Protestant succession was traditional. And for the second in line to the Dutch throne to not only convert to Roman Catholicism, but to marry the heir to the Carlist claimant of the Spanish throne, had caused shock in the Netherlands.
No one from the Dutch royal family or any Dutch diplomatic representative attended the marriage of Princess Irene and Prince Carlos Hugo in the Borghese Chapel at the Basilica di Santa Maria Maggiore in Rome, Italy, on 29 April 1964.
But having been married to the Prince and Duke of Parma, Princess Irene is the only one among her sisters whose husband was of royal status.
Princess Irene and Prince Carlos Hugo shared four children: Prince Carlos, Duke of Parma; Princess Margarita, Countess of Colorno;
Prince Jaime, Count of Bardi; and
Princess Carolina, Marchioness of Sala.
In 1980, Princess Irene and her children returned to the Netherlands, initially moving back into Soestdijk Palace. She and Prince Carlos Hugo (who passed away in 2010) div0rced in 1981.
