House of Nassau


The House of Nassau is a diversified aristocratic dynasty in Europe. It is named after the lordship associated with Nassau Castle, located in present-day Nassau, Rhineland-Palatinate, Germany. The lords of Nassau were originally titled "Count of Nassau", then elevated to the princely class as "Princely Counts". Early on they divided into two main branches: the elder branch, that gave rise to the German Emperor Adolf, and the younger branch, that gave rise to the Princes of Orange and the monarchs of the Netherlands.
At the end of the Holy Roman Empire and the Napoleonic Wars, the Walramian branch had inherited or acquired all the Nassau ancestral lands and proclaimed themselves, with the permission of the Congress of Vienna, the "Dukes of Nassau", forming the independent state of Nassau with its capital at Wiesbaden; this territory today mainly lies in the German Federal State of Hesse, and partially in the neighbouring State of Rhineland-Palatinate. The Duchy was annexed in 1866 after the Austrian-Prussian War as an ally of Austria by Prussia. It was subsequently incorporated into the newly created Prussian Province of Hesse-Nassau.
Today, the term Nassau is used in Germany as a name for a geographical, historical and cultural region, but no longer has any political meaning. All Dutch and Luxembourgish monarchs since 1815 have been senior members of the House of Nassau. However, in 1890 in the Netherlands and in 1912 in Luxembourg, the male lines of heirs to the two thrones became extinct, so that since then, they have descended in the female line from the House of Nassau.
According to German tradition, the family name is passed on only in the male line of succession. The House would therefore, from this German perspective, have been extinct since 1985. However, both Dutch and Luxembourgish monarchial traditions, constitutional rules and legislation in that matter differ from the German tradition, and thus both countries do not consider the House extinct. The Grand Duke of Luxembourg uses "Duke of Nassau" as his secondary title and a title of pretense to the dignity of Chief of the House of Nassau, but not to lay any territorial claims to the former Duchy of Nassau which is now part of the Federal Republic of Germany.

Origins

is considered the founder of the House of Nassau. He is first mentioned in the purported founding-charter of Maria Laach Abbey in 1093. The Castle Laurenburg, located a few kilometres upriver from Nassau on the Lahn, was the seat of his lordship. His family probably descended from the Lords of Lipporn. In 1159, Nassau Castle became the ruling seat, and the house is now named after this castle.
The Counts of Laurenburg and Nassau expanded their authority under the brothers Rupert I and Arnold I. Rupert was the first person to call himself Count of Nassau, but the title was not confirmed until 1159, five years after Rupert's death. Rupert's son Walram I was the first person to be legally titled Count of Nassau.
The chronology of the Counts of Laurenburg is not certain and the link between Rupert I and Walram I is especially controversial. Also, some sources consider Gerhard, listed as co-Count of Laurenburg in 1148, to be the son of Rupert I's brother, Arnold I. However, Erich Brandenburg in his Die Nachkommen Karls des Großen states that it is most likely that Gerhard was Rupert I's son, because Gerard was the name of Beatrix of Limburg's maternal grandfather.

Counts of Laurenburg (ca. 1093–1159)

Counts of Nassau in Wiesbaden, Idstein, and Weilburg (1255–1344)

After Gerlach's death, the possessions of the Walram line were divided into Nassau-Weilburg and Nassau-Wiesbaden-Idstein.

Nassau-Weilburg (1344–1816)

Count Walram II began the Countship of Nassau-Weilburg, which existed to 1816. The sovereigns of this house afterwards ruled the Duchy of Nassau until 1866 and from 1890 the Grand Duchy of Luxembourg. The branch of Nassau-Weilburg ultimately became rulers of Luxembourg. The Walram line received the lordship of Merenberg in 1328 and Saarbrücken in 1353.

Counts of Nassau-Weilburg (1344–1688)

In 1866, Prussia annexed the Duchy of Nassau as the duke had been an ally of Austria in the Second Austro-Prussian War. In 1890, Duke Adolf would become Grand Duke Adolphe of Luxembourg.

Grand Dukes of Luxembourg (from the House of Nassau-Weilburg) – 1890–1912 and succession through a female onwards

From a morganatic marriage, contracted in 1868, descends a family, see Count of Merenberg, which in 1907 was declared non-dynastic. Had they not been excluded from the succession, they would have inherited the headship of the house in 1912.

Counts of Nassau-Wiesbaden-Idstein (1344–1728)

After Frederick Louis's death, Nassau-Wiesbaden-Idstein fell to Charles, Prince of Nassau-Usingen

Counts of Nassau-Saarbrücken (1429–1797)

After Henry Louis's death, Nassau-Saarbrücken fell to Charles William, Prince of Nassau-Usingen until Adolph came of age in 1805.

Princes of Nassau-Usingen (1659–1816)

In 1816, Nassau-Usingen merged with Nassau-Weilburg to form the Duchy of Nassau. See "Dukes of Nassau" above. The princely titles continued to be used, however, evidenced by the carrying of the title Prince of Nassau-Weilburg by the Grand Duke of Luxembourg. Following Frederick Augustus' death, the princely title was adopted by his half brother through an unequal marriage, Karl Philip. As head of the House in 1907, Wilhelm IV declared the Count of Merenberg non-dynastic; by extension, this would indicate that this branch would assume the Salic headship of the house in 1965, following the death of the last male Count of Merenberg.

The Ottonian Line

In 1303, Otto's sons divided the possessions of the Ottonian line. Henry received Nassau-Siegen, John received Nassau-Dillenburg and Emicho I received Nassau-Hadamar. After John's death. Nassau-Dillenburg fell to Henry.

Counts of Nassau-Dillenburg

In 1739, Nassau-Dillenburg fell to Nassau-Dietz, a.k.a. Orange-Nassau.

Counts of Nassau-Beilstein

In 1343, Nassau-Beilstein was split off from Nassau-Dillenburg.
After John III's death, Nassau-Beilstein fell back to Nassau-Dillenburg. It was split off again in 1607 for George, who inherited the rest of Nassau-Dillenburg in 1620.

Counts and Princes of Nassau-Hadamar

After Emicho III's death, Nassau-Hadamar fell back to Nassau-Dillenburg.
In 1620, the younger line of Nassau-Hadamar was split off from Nassau-Dillenburg
In 1711, Nassau-Hadamar was divided between Nassau-Dietz, Nassau-Dillenburg, and Nassau-Siegen.

Nassau-Siegen

The branch of Nassau-Siegen was a collateral line of the House of Nassau, and ruled in Siegen. The first Count of Nassau in Siegen was Count Henry I, the elder son of Count Otto I of Nassau. His son Count Otto II of Nassau ruled also in Dillenburg.
In 1328, John of Nassau-Dillenburg died unmarried and childless, and Dillenburg fell to Henry of Nassau-Siegen. For counts of Nassau-Siegen in between 1343 and 1606, see "Counts of Nassau-Dillenburg" above.
In 1606 the younger line of Nassau-Siegen was split off from the House of Nassau-Dillenburg. After the main line of the House became extinct in 1734, Emperor Charles VI transferred the county to the House of Orange-Nassau.

Counts and Princes of Nassau-Siegen

In 1734, Nassau-Siegen fell to Nassau-Dietz, a.k.a. Orange-Nassau.

Counts and Princes of Nassau-Dietz

When the Nassau lands were divided by the sons of John, Count of Nassau-Dillenburg, the brother of William the Silent, the main part of the Counts of Nassau-Dietz was the town of Diez:
In 1702, the Nassau-Dietz branch followed the House of Orange that had become extinct with William III of England. The counts of Nassau-Dietz not only descended from William I., the Silent's, brother, but in female line also from himself, as William Frederick, Prince of Nassau-Dietz, had married Countess Albertine Agnes of Nassau, the fifth daughter of Frederick Henry, Prince of Orange in 1652. She had Oranienstein Palace built from 1672 as her new residence at Diez.
Their grandson Johan Willem Friso became Stadholder in Friesland and Groningen, and in 1702 became the heir of William III of England and thus the founder of the younger House of Orange-Nassau and of the Dutch Royal Family. However, he had to split the Dutch properties with the King of Prussia who also descended from William I. Johan Willem Friso's son, William IV, Prince of Orange, inherited a number of Nassau territories besides his paternal Nassau-Dietz, namely Nassau-Hadamar in 1711, Nassau-Siegen in 1734, and Nassau-Dillenburg in 1739. In 1732, Frederick William I of Prussia left him his Dutch properties, including Huis ten Bosch palace and Het Loo Palace. William IV became stadtholder of the Netherlands in 1747 and reunited all of the Dutch and German possessions of his family in his hand, styling himself Prince of Orange and Nassau.
The county of Nassau-Diez, like other Nassau territories, was occupied by Napoleonic France in 1795 and in 1806 was annexed by the Duchy of Nassau on 16–17 September 1796 as a consequence of the 2nd Coalition war between Austrians and French in the area between Diez and Limburg. By the end of the 18th century the entire west bank of the Rhine went to France and in 1803 a new Principality of Orange was formed from other territories, however only to be divided between the Duchy of Nassau and the Grand Duchy of Berg in 1806. William I of the Netherlands recovered his former counties in 1813, but gave Nassau-Diez, Nassau-Hadamar und Nassau-Dillenburg to Prussia, in exchange with Luxembourg, two years later. Prussia kept only Nassau-Siegen and soon ceded the other counties to the Duchy of Nassau which was however annexed by Prussia, including Diez, after the Austro-Prussian War in 1866, for Nassau's support of Austria.

Orange-Nassau

The House of Orange-Nassau stems from the Ottonian Line. The connection was via Engelbert I, who offered his services to the Duke of Burgundy and married a Dutch noblewoman, Johanna van Polanen, who inherited the vast lands of the House of Polanen in the Netherlands, with the barony of Breda as the core of the future Dutch possessions of the House of Nassau-Dillenburg.
The importance of the Nassaus grew throughout the 15th and 16th century. Henry III of Nassau-Breda was appointed stadtholder of Holland, Zeeland and Utrecht by Emperor Charles V in the beginning of the 16th century. Henry was succeeded by his son, René of Châlon-Orange in 1538, who was, as can be inferred from his name, a Prince of Orange. When René died prematurely on the battlefield in 1544 his possessions and the princely title passed to his cousin, William the Silent, a Count of Nassau-Dillenburg. By dropping the suffix name "Dillenburg", from then on the family members called themselves "Orange-Nassau."
With the death of William III, the legitimate direct male line of William the Silent became extinct and thereby the first House of Orange-Nassau. John William Friso, the senior agnatic descendant of William the Silent's brother and a cognatic descendant of Frederick Henry, grandfather of William III, inherited the princely title and all the possessions in the low countries and Germany, but not the Principality of Orange itself. The Principality was ceded to France under the Treaty of Utrecht that ended the wars with King Louis XIV. John William Friso, who also was the Prince of Nassau-Dietz, founded thereby the second House of Orange-Nassau.
The Revolutionary and Napoleonic era was a tumultuous episode of the history of both the Ottonian and Walramian branches of the House of Nassau. France's dominance of the international order severely strained the House of Nassau's traditional strategy of international conflict resolution, which was to maintain links with all serious power-brokers through a dynastic network in the hope of maintaining a balance of power. Despite that both branches of the House of Nassau reinvigorated the dynastic network in the years of liberation, 1812–1814, the post-Napoleonic European order saw both branches set on different historical paths.
After the post-Napoleonic reorganization of Europe, the head of House of Orange-Nassau gained the title "King/Queen of the Netherlands" and "Grand Duke of Luxembourg". The latter was gained, with permission of the Congress of Vienna by trading the ancestral Ottonian Nassau lands in Germany to their Walramian cousins for the duchy of Luxembourg, which was closer to their power center of Holland, and remained in personal union with the Kingdom of the Netherlands until the death of the last male Ottonian, King William III of the Netherlands. The King of Prussia, who also had a claim to the principality of Orange received lands in the Ruhr. In this way, everyone consolidated more land nearer their power bases.
