Early life

Prince Lorenz was born in Belvedere Clinic, Boulogne-Billancourt, Hauts-de-Seine, France, as the second child of Robert, Archduke of Austria-Este and his wife, Archduchess Margaret (née Princess Margherita of Savoy-Aosta).

Education and career

After finishing school, Archduke Lorenz did his military service in the regiment of Gebirgsjäger ("Alpine Hunters") of the Federal Austrian Army, and he was promoted to Reserve Leutnant (Second Lieutenant) in 1980.[1]

Lorenz studied economics at the University of St. Gallen in Switzerland and the University of Innsbruck in Austria. He then worked at various banks in London, Paris, and Rome. In 1983, he joined the Gutzwiller private bank in Basel, where he eventually became a Managing Partner. In 1993, he spent one year as a consultant to SWIFT, a company which provides services to the financial industry. In 1995, he became Advisor to the Board of Directors of BNP Paribas bank in Paris. He was formerly a director of UCB, Sita (a worldwide waste management company located in France) and Ondeo Nalco (a water management company in the United States).


On 22 September 1984 in Brussels, Lorenz married Princess Astrid of Belgium, the only daughter of the then-Prince and Princess of Liège, former King Albert II and Queen Paola. The couple have five children and two grandchildren:

Prince Lorenz is a godfather to Prince Carl-Johan of Nassau, youngest child of Prince Jean of Luxembourg and Count Costantino Secco di Aragona, oldest son of his cousin Archduchess Catharina-Maria of Austria.


Since 2004, Lorenz has been the honorary president of the Council of the Koninklijke Vereniging der Historische Woonsteden van België/Association Royale des Demeures Historiques de Belgique.[2] Since 2005, he has been the Patron of Europae Thesauri, an association of European cathedral and church treasuries.[3]

Lorenz has also served as deputy chairman of the Société des Amis of the Almanach de Gotha.[4]

He is named member of the Royal Crown Council of Romania in 2015.[5]

Titles and styles

  • 16 December 1955 – 10 November 1995: His Imperial and Royal Highness Archduke Lorenz of Austria-Este
  • 10 November 1995 – 7 February 1996: His Imperial and Royal Highness Prince Lorenz of Belgium, Archduke of Austria-Este
  • 7 February 1996 – present: His Imperial and Royal Highness Prince Lorenz of Belgium, The Archduke of Austria-Este

As head of the House of Austria-Este since his father's death on 7 February 1996, Lorenz bears the titles "Archduke of Austria-Este".[6][7] The name and arms of Este were made hereditary according to male primogeniture by declaration of Emperor Franz Joseph I of Austria on 31 October 1914 (following the assassination of Archduke Franz Ferdinand of Austria-Este) and was confirmed by Imperial Austrian letters patent, both of which conferred it (with the traditional coat-of-arms of the House of Austria-Este) upon Lorenz's father, Archduke Robert, on 16 April 1917,[8][9][10] and has been confirmed for Lorenz by specific reference in Article IX.1 of the constitution of the Kingdom of Belgium. The Este suffix descended by male primogeniture and is borne by Lorenz and his successors as heads of the Austria-Este cadet branch of the House of Habsburg-Lorraine.[8][9]

Since Prince Lorenz and his family are also members of the House of Habsburg, they also bear the more extended traditional Habsburg titles of "Prince Royal of Hungary, Croatia and Bohemia",[8][9] although they are seldom referred with that internationally[11] and all noble, royal, and imperial titles have been abolished and are forbidden in Austria and in Hungary.[fn 1] In addition to the previous ones, Prince Lorenz also holds the pretension title of "Duke of Modena and Reggio", who inherited this title from his father Archduke Robert of Austria-Este who in turn inherited this from Charles I, Emperor of Austria. Archduke Robert was chosen by the Emperor to preserve, in the form of a distinct secundogeniture, the Habsburg-Lorraine representation of the once-sovereign Duchy of Modena which had belonged to the House of Este.[12]

The title "Prince of Belgium" was granted to him by Royal Decree of 10 November 1995 by his father-in-law, King Albert II of the Belgians.[13][14] Depending on the situation, Lorenz is thus legally and formally styled HRH Prince Lorenz of Belgium, or internationally otherwise HI&RH Prince Lorenz of Belgium, Archduke of Austria-Este or simply HI&RH The Archduke of Austria-Este.

His children by Princess Astrid bear the titles "Prince(ss) of Belgium", by Belgian decree of 2 December 1991, in addition to their traditional Austrian titles, "Archduke/Archduchess of Austria, Prince(ss) Royal of Hungary".
