Grand Duchy
of Luxemburg
Groussherzogtum Lëtzebuerg
The Grand Duchy of Luxembourg is a landlocked country
in western Europe, bordered by Belgium, France, and Germany. It has two principal regions: the Oesling in the North as part
of the Ardennes massif, and the Gutland ("good country") in the south. Luxembourg has a population of over half
a million people in an area of approximately 2,586 square kilometres (998 sq mi). A representative democracy with a constitutional
monarch, it is ruled by a grand duke. It is now the world's only remaining sovereign grand duchy. The country has a highly
developed economy, with the world's highest GDP (nominal) per capita according to the IMF. Its historic and strategic importance
dates back to its founding as a Roman era fortress site and Frankish count's castle site in the Early Middle Ages. It was
an important bastion along the Spanish Road when Spain was the principal European power influencing the whole western hemisphere
and beyond in the 16th-17th centuries.
Luxembourg
is a member of the European Union, NATO, OECD, the United Nations, and Benelux, reflecting the political consensus in favour
of economic, political, and military integration. The city of Luxembourg, the largest and capital city, is the seat of several
institutions and agencies of the EU. Luxembourg culture is a mix of Romance Europe and Germanic Europe, borrowing customs
from each of the distinct traditions. Luxembourg is a trilingual country; German, French and Luxembourgish are official languages.
Although a secular state, Luxembourg is predominantly Roman Catholic.
Grand Ducal Family of Luxembourg
The Grand Ducal Family of Luxembourg (House of Nassau-Weilburg,
agnatically, a cadet branch of the House of Bourbon-Parma, itself a cadet branch of the House of Bourbon, in turn a cadet
branch of the House of Capet) consists of the extended family of the sovereign Grand Duke. The medieval duchy of Luxembourg was elevated to a grand duchy in 1815; William I of the
Netherlands ascended the grand ducal throne as its first holder. William, through his Prussian mother, was a descendant of
the medieval heiress Anne, Duchess of Luxembourg, as was William's wife, his first cousin. The territories of the grand duchy,
taken (including the ancestral castle of Luxembourg) from occupying French forces in the first stages of the fall of Napoleon,
had been ceded to William by his first cousin King Frederick William III of Prussia, who was Anne's heir-general. In breach
of the traditional line of succession of Luxembourg, the great powers of Europe agreed that the grand duchy would be inherited
in the male line of the House of Nassau.
House of Nassau-Weilburg
The House of Nassau-Weilburg ruled a division of Nassau, which was a state in current Germany,
a state that existed from 1344 to 1806. On July 17, 1806 the counties of Nassau-Usingen and Nassau-Weilburg joined the Confederation
of the Rhine. Under pressure from Napoleon both counties merged to become the Duchy of Nassau on August 30, 1806 under joint
rule of Prince Frederick August of Nassau-Usingen and his younger cousin Prince Frederick William of Nassau-Weilburg. As Frederick
August had no heirs he agreed that Frederick William should become sole ruler after his death. However Frederick William died
from a fall on the stairs at Weilburg Castle on 9 January 1816 and it was his son William who became duke of a unified Nassau.
The sovereigns of this house afterwards governed
the Duchy of Nassau until 1866, and since 1890 they have governed the nation of Luxembourg. The House of Nassau-Weilburg became
extinct in the male line with the death of Grand Duchess Charlotte of Luxembourg in 1985. However, the name has been carried
on in the bilineal line, with the official name of the reigning house of Luxembourg remaining Nassau-Weilburg. Since the death
of the Grand Duchess, members of the reigning house are cognatically members of the House of Nassau-Weilburg and agnatically
members of the House of Bourbon-Parma.
The List of the Grand Dukes of Luxembourg
The Grand Duke of Luxembourg is the head
of state of Luxembourg. Luxembourg is the world's only sovereign extant Grand Duchy, a status to which Luxembourg was promoted
in 1815 upon its unification with the Netherlands under the House of Orange-Nassau.

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.

The Family Titles and Styles
Traditionally, the members of this family bear the titles
Prince or Princess of Luxemburg, Bourbon-Parma and Nassau, together with the formal appellation of His or Her Royal Highness.
The Arrêté Grand-Ducal of 21 Septembre 1995 etablished that the title of "Prince or 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 or Princesse de Nassau" with qualification of "Altesse Royale"
and that the descendants of non-approved mariages should be styled as "Comte or Comtesse de Nassau". On 27 November
2004 Grand-duc Henri issued another Arrêté Grand-Ducal upgrading the issue of Prince Jean to "Prince or
Princesse de Nassau" with the qualification of "Altesse Royale" and upgrading the wife and issue of Prince
Robert to "Prince Prinesse de Nassau" with qualification of "Altesse Royale". In June 2009 another Arrêté
Grand-Ducal was issued upgrading the issue of Prince Louis to "Prince or Princesse de Nassau" with the qualification
of "Altesse Royale" and upgrading his wife Tessy "Altesse Royale Princesse de Luxembourg".
