Prince Guillaume, Hereditary Grand Duke of Luxembourg (given names: Guillaume Jean Joseph Marie; born 11 November 1981), has been heir apparent to the crown of Luxembourg since his father's accession in 2000.

Early life and education[edit]

Prince Guillaume was born in 11 November 1981 at the Grand Duchess Charlotte Maternity Hospital in Luxembourg City and is the eldest child of Grand Duke Henri of Luxembourg and his wife, Cuban-born Grand Duchess Maria Teresa.[1] He was named after his father's youngest brother Prince Guillaume of Luxembourg. His godparents are Princess Marie Astrid of Luxembourg and Prince Guillaume of Luxembourg. Guillaume has four younger siblings: Prince Félix, Prince Louis, Princess Alexandra and Prince Sébastien.

Guillaume's education includes Lycée Robert-Schumann in Luxembourg; Collège Alpin International Beau Soleil and Institut Le Rosey boarding schools in Switzerland; and Royal Military Academy Sandhurst, Camberley, England. He began his higher education studies in the United Kingdom where he studied at University College, Durham and Brunel University, both in England. In 2006 he entered Institut Philanthropos in Fribourg, Switzerland, where he spent a year studying philosophy and anthropology. He later studied letters and political science at the Institut Albert-le-Grand in Angers, receiving his bachelor's degree with honors in 2009. His degree was issued by Université d'Angers, as a result of a partnership agreement between the two schools.[2][3]

Hereditary Grand Duke[edit]

Guillaume has been heir apparent to the crown of Luxembourg since his father's accession in 2000. If he succeeds to the grand ducal throne, he will reign as the fifth of his name, Guillaume (English: William) V. He has been honorary chairman of the Board of Economic Development of Luxembourg since 2001. He was formerly active with the Kraizberg Foundation, a charitable institution for the disabled.[1]


At the occasion of his 30th birthday, he gave interviews during which stated that he was in a relationship with a "dear miss" that had been going strong for more than a year but insisted that they need some more time to evaluate their possible future. On 26 April 2012, the court announced the engagement of the Hereditary Grand Duke to the Belgian Countess Stéphanie de Lannoy.[4] Guillaume and Stéphanie share a common descent from Charles Marie, Prince & 5th Duke d’Arenberg, which means that Guillaume's father and Stéphanie are 7th cousins; thus Guillaume is Stéphanie's 7th cousin once removed.

The civil wedding took place on Friday, 19 October 2012; the religious wedding took place on Saturday, 20 October 2012 at the Notre-Dame Cathedral.[5]

Hereditary Grand Duke Guillaume and Hereditary Grand Duchess Stéphanie will move to London later this year 2018.[6]


Guillaume is interested in music and sports; he plays the piano and enjoys football, swimming and volleyball. He speaks Luxembourgish, French, German, Spanish and English. He regularly represents his parents in many foreign activities.[1]

  7. ^ In 1986, Grand Duke Jean renounced the title Prince/Princesse de Bourbon de Parme for himself and his family, when his eldest son, then-Hereditary Grand Duke Henri married Maria-Theresa Mestre. The reason for this was that the Duke of Parma, Carlos Hugo, ruled the marriage unequal in 1981, as well as the marriage of Prince Jean to Hélène Suzanna Vestur in 1987, for which he had renounced his rights to Luxembourger throne in 1986.
  8. ^ The Arrêté Grand-Ducal of 21 Septembre 1995 established that the title of Prince/Princesse de Luxembourg is reserved for the children of the sovereign and the heir to the throne. It also stated that the descendants in male lineage of the sovereign should be styled as Prince/Princesse de Nassau with qualification of Altesse Royale.
