Monarchy of Luxembourg - wikipedia Monarchy of Luxembourg Grand Duke of Luxembourg Coat of Arms of Luxembourg Incumbent Henri since 7 October 2000 ( 2000 - 10 - 07 ) Details Style His Royal Highness Heir apparent Guillaume, Hereditary Grand Duke of Luxembourg First monarch William I of the Netherlands ( 1815, personal union began ) Adolphe, Grand Duke of Luxembourg ( after 1890 ) Formation 15 March 1815 Residence Grand Ducal Palace in Luxembourg Website Monarchie.lu ( in French ) The Grand Duke of Luxembourg is the monarchical head of state of Luxembourg. Luxembourg has been a grand duchy since 15 March 1815, when it was elevated from a duchy, and was in personal union with the United Kingdom of the Netherlands until 1890 under the House of Orange - Nassau and is the world 's only sovereign grand duchy. Since 1815, there have been nine monarchs of Luxembourg, including the incumbent, Henri.

He exercises executive power in accordance with the constitution and the laws of the country. After a constitutional change ( to article 34 ) in December 2008 resulting from Henri 's refusal to assent to a law legalizing euthanasia, laws now no longer require the grand duke 's formal assent ( implying `` approval '' ) but his task of promulgating the law as chief executive remains. Succession Main article : Line of succession to the Luxembourger throne Succession to the throne was governed by Salic law, as dictated by the Nassau Family Pact, first adopted on 30 June 1783. The right to reign over Luxembourg was until June 2011 passed by agnatic - cognatic primogeniture within the House of Nassau, as stipulated under the 1815 Final Act of the Congress of Vienna and as confirmed by the 1867 Treaty of London. The Nassau Family Pact itself can be amended by the usual legislative process, having been so on 10 July 1907 to exclude the Count of Merenberg branch of the House, which was descended from a morganatic marriage. An heir apparent may be granted the style ' Hereditary Grand Duke '. The current heir apparent is Hereditary Grand Duke Guillaume. In June 2011, agnatic primogeniture was dropped in favour of absolute primogeniture, allowing any legitimate female descendants within the House of Nassau to be included in the line of succession. Full titles The traditional titulatures of the grand duke are : By the Grace of God, Grand Duke of Luxembourg, Duke of Nassau, Count Palatine of the Rhine, Count of Sayn, Königstein, Katzenelnbogen and Diez, Burgrave of Hammerstein, Lord of Mahlberg, Wiesbaden, Idstein, Merenberg, Limburg and Eppstein. It should, however, be noted that many of the titles are held without regard to the strict rules of Salic inheritance and that most, save for Grand Duke of Luxembourg and Duke of Nassau, are simply not used. List of Grand Dukes Main article : List of monarchs of Luxembourg House of Orange - Nassau Image Name Date of birth Date of death Reign Relationship with predecessor Guillaume I Willem Frederik ( Prince William VI of Orange ) 24 August 1772 12 December 1843 15 March 1815 -- 7 October 1840 Francis ' third cousin and Anne 's direct descendant Guillaume II Willem Frederik George Lodewijk 6 December 1792 17 March 1849 7 October 1840 -- 17 March 1849 Son of William I Guillaume III Willem Alexander Paul Frederik Lodewijk 17 February 1817 23 November 1890 17 March 1849 -- 23 November 1890 Son of William II House of Nassau - Weilburg Under the 1783 Nassau Family Pact, those territories of the Nassau family in the Holy Roman Empire at the time of the pact ( Luxembourg and Nassau ) were bound by semi-Salic law, which allowed inheritance by females or through the female line only upon extinction of male members of the dynasty. When William III died leaving only his daughter Wilhelmina as an heir, the crown of the Netherlands, not being bound by the family pact, passed to Wilhelmina. However, the crown of Luxembourg passed to a male of another branch of the House of Nassau : Adolphe, the dispossessed Duke of Nassau and head of the branch of Nassau - Weilburg. In 1905, Grand Duke Adolphe 's younger half - brother, Prince Nikolaus Wilhelm of Nassau, died, having left a son Georg Nikolaus, Count von Merenberg who was, however, the product of a morganatic marriage, and therefore not legally a member of the House of Nassau. In 1907, Adolphe 's only son, William IV, Grand Duke of Luxembourg, obtained passage of a law confirming the right of his eldest daughter, Marie - Adélaïde, to succeed to the throne in virtue of the absence of any remaining dynastic males of the House of Nassau, as originally stipulated in the Nassau Family Pact. She became the grand duchy 's first reigning female monarch upon her father 's death in 1912, and upon her own abdication in 1919, was succeeded by her younger sister Charlotte, who married Felix of Bourbon - Parma, a prince of the former Duchy of Parma. Charlotte 's descendants have since reigned as the continued dynasty of Nassau, and also constitute a cadet branch of the House of Bourbon - Parma.
