Luxembourg's territories, centering on the ancestral castle, were captured from occupying French forces in the first stages of the fall of Napoleon. Some were eventually ceded to William VI of Nassau, Prince of Orange, who had been declared Sovereign Prince of the Netherlands in 1813, by his cousin King Frederick William III of Prussia who annexed other territories which had been held by princes of the various branches of the House of Nassau.[2] The Great Powers agreed at the Congress of Vienna in 1815 to re-constitute and elevate Luxembourg into a grand duchy, to be hereditary in the male line of the entire House of Nassau, beginning with the Prince of Orange, who was simultaneously but separately recognised as King of the Netherlands.
Thus William I of the Netherlands ascended the grand ducal throne as the first grand duke of Luxemburg. When the male line of the House of Orange-Nassau became extinct in 1890, the crown of the Netherlands went to his descendant, Wilhelmina of Orange-Nassau, but the crown of Luxembourg continued in the male line, devolving upon the head of the only surviving branch of the House of Nassau, ex-Duke Adolf of Nassau-Weilburg. His son, Guillaume IV (reigned 1905–1912), left no sons and was succeeded by his daughters, Marie-Adélaïde and then by Charlotte (reigned 1919–1964). Her descendants (from her marriage to Prince Felix of Bourbon-Parma) comprise the Grand Ducal House in the 21st century.
Since the grand ducal decree of 21 September 1995, dynasts who are the children of a grand duke or hereditary grand duke hold the titles "Prince/Princess of Luxembourg" and "Prince/Princess of Nassau" with the style of Royal Highness.[3] Shortly after his accession to the throne in October 2000, Grand Duke Henri issued a grand ducal decree conferring upon his eldest son and heir, Prince Guillaume, the title of "Hereditary Grand Duke" and restoring to him the title "Prince of Bourbon-Parma".[5] Male line descendants of Grand Duchess Charlotte who are not the children of a grand duke or hereditary grand duke are "Prince/Princess of Nassau" with the style of His/Her Royal Highness.[3]
A grand ducal decree in 2012, concerning the family pact, further defined the rules of titles borne.[6]
The wives, children and male-line descendants of a prince of the dynasty whose marriage has not received grand ducal consent are "Count/Countess de Nassau".[3]
To date, the title of "His/Her Royal Highness Prince/Princess of Bourbon-Parma" has been returned to all legitimate members of the grand ducal family.[7] Indeed, the members of the grand ducal family have never ceased to actually be members of the Royal House of Bourbon-Parma.[8][9][10][11][12][13][14][15][16]
Religion
Grand Dukes Adolphe (1817–1905) and William IV (1852–1912) were Evangelical Christians. William married the Roman Catholic Marie Anne of Portugal, believing that a country in which the great majority of people were Roman Catholic should also have a Roman Catholic monarch. In 1907, William declared the Evangelical Counts of Merenberg to be non-dynastic and named his own Roman Catholic daughter, Marie-Adélaïde (1894–1924), heiress to the grand ducal throne; she in 1919 abdicated in favour of her sister, Charlotte (1896–1985), who was also Roman Catholic, and Charlotte's Roman Catholic descendants have reigned in Luxembourg ever since.
However, although Roman Catholicism is the claimed faith of the overwhelming majority of the Luxembourgish people (ca. 90–93%), it does not have the status of a state religion, nor is there any legal or constitutional obligation for the grand duke (as head of state) to be Roman Catholic.

The preference for men over women in succession to Luxembourg's throne was abandoned in favour of absolute primogeniture on 20 June 2011 by decree of Grand Duke Henri.[20] Henceforth, any legitimate female descendant of the House of Luxembourg-Nassau born of authorized marriage shall inherit the throne by order of seniority of line of descent and of birth as stipulated in Article 3 of the Constitution and the Nassau Family Pact without regard to gender, applicable first to succession by the descendants of Grand Duke Henri.[21] The Grand Duke's marshal issued an addendum to the decree explaining the context of the change: pursuant to the United Nations' 1979 call for nations to eliminate all forms of discrimination against women, in 2008 the grand duchy dropped the exception to gender non-discrimination it had declared in the matter of the grand ducal succession.[22]
