The Ducal House of Nassau

House of Nassau

The 1093 mentoned Dudo of Laurenburg is presumed progenitor of the House. The castle Laurenburg, a few kilometers upstream location of Nassau an der Lahn, was the seat of government of the Family, previously believed to be the place Lipporn. 1159 Nassau Castle became the seat of the Family, which has since been named after this castle.The counts of Laurenburg and Nassau advanced among the brothers Arnold I. of Laurenburg (1123-1148) and Ruprecht I (1123-1154), whose son Walram I. (1154-1198) and Walrams son Heinrich II., the rich ( 1198-1247) constantly their belongings in the space between Taunus and Westerwald on the lower and middle Lahn. Before 1128 they acquired the bailiwick of the Monastery Worms, which had a number of rights in the area, thus creating a connection between their heritage on the lower Lahn and their possession to Siegen. In the mid-12th century, this connection was strengthened with the acquisition of so-called Hessian-Thuringian Imperial fief, namely Herborner Mark, the Kalenberger centering and the Court Heimau (Löhnberg). Closely related to this was the “rule of the Westerwald,” which also came at this time in Nassau possession. The late 12th century was acquired in the southwest with the Reichshof Wiesbaden an important base .
Heinrich II. sons Walram II. and Otto I divided their land in 1255 into two parts and their house in two lines, which are named after them Ottonian and Walramische line. Boundary line was essentially the Lahn, where Otto received the northern part of the country with Siegen, Dillenburg, Herborn and Haiger and Walram received the south of the river located part of the county with Weilburg and Idstein

Nassau-Hadamar older line

 In the division of 1303 Count Emich got Nassau-Hadamr with Deriedrof and the Esterau. The possession of Driedorf was not without controversy, since it was a fief of the Landgrafschaft of Hesse, and between the landgraves and the Ottonian main line of the House Nassau a feud existed. It was not until 1316 that Emicho succeeded in acquiring the share of the Lords of Greifenstein at Driedorf for 250 marks. His son Johann initially continued his father’s acquisition policy. In 1324 the lords of Westerburg pledged half of the Schaumburg to him. In 1337 he succeeded in acquiring the rule of Ellar with its four-cent, numerous localities and the district court of Count Gottfried von Diez for 1450 Mark Limburger money. From about 1348, on the other hand, Johann’s policy was determined by divestments and pledges. Driedorf was pledged several times, and the reign of Ellar was bought back by the County of Diez before 1362, the half of Ems and Dausenau was pledged to Kurtrier in 1363, and the Franconian property around Burg Kammerstein was completely sold until 1364.
After the death of Count Heinrich, the Hadamarer  Disput of successions began.  Nominell was Emicho III. Count of Nassau-Hadamar until 1394. However, he was regarded as “stupid” and non-governmental and was exiled by his family in the monastery Arnstein.
The government in Hadamar took over Emich’s brother-in-law Ruprecht VI. of Nassau-Sonnenberg, from the Walramian line of the house of Nassau.  who was married to Anna of Nassau-Hadamar, a daughter of Count Johann. At the same time Emich’s cousin Johann I of Nassau-Dillenburg, as a senior of the Ottonian line, raised inheritance claims on the county.At the latest 1371 came an open break between Ruprecht VI. of Nassau-Sonnenberg and Johann I of Nassau-Dillenburg. Landgraf Henry II of Hesse supported Ruprecht and handed over to him and his wife Anna two-thirds of the court Driedorf, which had been confiscated by him the previous year, as a fief. Johann I. von Nassau-Dillenburg then joined the Starfleet against the Landgrave. On 06.06.1390, Johann and Ruprecht agreed again. Already a few months later on 04.11.1390 died Ruprecht VI. His widow Anna married again to Counter Diether VII. of Katzenelnbogen who soon raised his claims to Nassau-Hadamar.  As this marriage remained without children Anna’s claim went to her stepson Johann IV. of Katzenelnbogen. After Anna’s death in 1404, Johann I of Nassau-Dillenburg renewed his claim to the partial count. The new contest with a cat’s bow was settled on 17 August 1405. Nassau-Dillenburg received a third, catelbow two thirds of the county. Since Hesse refused his consent to the Driedorfer Lehen, the settlement was changed in the arbitration to Bacherach on 28.07.1408. Instead of a third at Driedorf, Nassau-Dillenburg received a third of the rule of Ellar, which had meanwhile acquired the County of Katzenelnbogen from the County of Diez

Nassau-Siegen from 1328 Nassau-Dillenburg

In the division of 1303 Count Heinrich III. got Nassau-Siegen with the Ginsterburg and the lhe rule of Westerwald. After the line Nassau-Dillenburg became extinct in 1328 he inherited their posession and changedf the name to Nassau-Dillenburg. After his death in 1343 his sons divied the posessions.  The older brother Otto received the larger part with the dominion area around Siegen and Dillenburg, Heinrich was with a relatively small part, the Kalenberger Zent around Beilstein and the dominion to the Westerwald resigned.
Under his son Johann I. the rise of Nassau-Dillenburg continued. By the marriage of his son Adolf with Jutta of Diez fell the in 1386 the county Diez 1386 to  Nassau-Dillenburg. However, only half of the county of Diez could be claimed, and one had to accept for them the feudal bishopliness of the bishop of Trier. In 1394, Nassau-Hadamar also fell to Nassau-Dillenburg.
It was of great importance for a long time that Johann I. married his son Engelbert to Johanna von Polanen, the heiress of the Count Polanen. As a result 1403/04 important possessions were acquired in the territory of the todays Netherlands, including the Poles, Leck, Breda and other areas. In the year 1420 they inherited the county Vianden in today’s Luxembourg and further possessions.
Under the reign of Johann IV , the focus of the rule shifted more and more into the dutch possessions. These fell to his son Engelbert II. , while his brother Johann V  received Dillenburg. Since Engelbert did not leave any heirs, his nephew, Johann’s son, Heinrich III.  which was able to considerably extend Nassau’s influence in the Netherlands. By marrying Claudia of Chalon and Orange, he acquired the Principality of Orange in the South of France. Thire son of Renatus (1519-44), became the first Nassau to take the sovereign title of “Prince of Orange”. Heinrich‘s brother Wilhelm, called the Riche inherited the Dillenburger posessions and introducded there until 1536 the Reformation. When the Breda line died out again, the oldest Dillenburg Prince resumed the legacy there. This was Wilhelms the rich son Wilhelm. The younger son Johann VI, called the Elder of Dillenburg, could, after the extinction of the older line of Beilstein in 1561, reconcile the entire Ottonian posession in his hand. In 1584 he founded the long-standing reformist High School Herborn. After his death, however, the country was again divided and the lines were created

As a Stadtholder of the Netherlands, he and his sons Philipp Wilhelm, Moritz  and Friedrich Heinrich led them into independence in the war of liberation from 1568 to 1648. His great-grandson  William III, The “last orange”, got in 1688  the English crown together with his wife Mary II. Stuart. After her death in 1694 he continued to reign as english King.

In the divison of 1341 Count Heinrich I. got Beilstein and the county Nasau-Beilstein was founded. Therefore Beilstein, which had already been granted city rights on 18.02.1321 and whose castle the Nassau counts began to expand from 1320 onwards, became the capital and administrative center of the eastern Westerwald. In the reign of the Westerwald, Nassau-Beilstein first had to contend with Westerburg. The counts received little income from the small territory of the region. Parts of the country had to be pledged repeatedly. The low income prevented a sustainable expansion of the rule by acquiring new territories. Likewise, extensive inheritance claims could not be enforced against other dynasties.  Inheritace claims  for the Isenburg-Grenzau domination.could noit be realized do to he early death of Count Philipp  in the Soester Feuds From the inheritance of the Johanna of Gemen († 1450/51), Heinirch  IV received the dominion Gemen. The house Nassau-Beilstein, however, could not hold this acquisition against the counts of Holstein-Schauenburg. As only gains remained the village of Niedernhausen, which Maria von Solms brought into marriage with Johann II in 1492, and the former sayn-dominations in the dominion of the Westerwald. The collaboration with electoral Cologne  developed more successfully for Nassau-Beilstein. Numerous members of the House were in the service in Cologne. Especially Heinrich III. reached an outstanding position as the archdeacon of the Cologne Cathedral. This enabled the counts to acquire far-reaching pledges throughout the electoral state , with a focus on Linz on the Rhine. It was not, however, possible to integrate these deposits into the county of Nassau-Beilstein.With the death of Johann III, who had only illegitimate descendants, the first line Nassau-Beilstein became extinct in 1561, and the county fell back to Nassau-Dillenburg.

After the death of Count Johann VI. of Nassau-Dillenburg his  son divided the posession on 31.03.1608 and the following lines emerged

County since 1650 Principality of Nassau-Hadamar younger line

When founded, the county included the Hadamar, Ellar and the Esterau offices as well as a quarter of Camberg, Altweilnau and Kirberg. After the death of Wilhelm-Ludwig of Nassau-Dillenburg, the Ottoman-Nassau countries were redistributed in 1620, and Johann Ludwig  won the offices of the chairy (Rennerod) and Mengerskirchen. As Count of Nassau-Hadamar, Johann Ludwig was anxious to consolidate his rule. In 1613 he acquired half of Altweilnau. In 1620 he succeeded in acquiring Maienburg from the Mudersbach family. With the “Probacher exchange” he received the villages of Dillhausen and Probbach against his district of Camberg on 08.05.1628 from Nassau-Diez. In 1631 he transferred his share of Altweilnau to Nassau-Saarbrücken and in return received the Walramische part of the Esterau. During the Thirty Years’ War, considerable war-induced enlargements occurred. In 1637, the office of Merenberg was acquired by Nassau-Weilburg. He lost these acquisitions with the peace conclusion, however. From Leiningen-Westerburg he bought the church play Seck 1637 and the church play Willmenrod 1644.  In 1643 he sold the Esterau and in the same year he acquired the Kirchspiel Neunkirchen from Nassau-Weilburg in the same year. The acquisition of Obertiefenbach in 1649 by the Wied-Runkel County rounded off the consolidation policy. In the course of the thirty years war, the Ottonian main line of the House of Nassau fell into disgrace with Emperor Ferdinand II, as the Calvinist counts supported the aims of the Reformed. In 1629 Johann Ludwig von traveled to the imperial court in Vienna, where he succeeded in securing the possessions of the Ottonian main line: he carried out the change from Calvinist to Catholic faith. Under Moritz Heinrich Nassau-Hadamar exchanged the Kirchspiel Wilmenrod in 1667 against the villages Wilsenroth and Pottum with Leiningen-Westerburg. With the death of Fürst Franz Alexander in 1711 the line Nassau-Hadamr became extinct in the male line.
The countryliness over the Principality fell to the remaining lines of the ottonian line of  the House of Nassau. After an initial joint administration the property was divided on 20.11.1717: Nassau-Siegen (catholic) and Nassau-Siegen (reformed) each received a sixth, Nassau-Dillenburg and Nassau-Diez each received a third. The distribution was carried out by lot. It was not until 1728 that the Emperor approved the division. The division was changed several times and remained unchallenged.

As early as 1702 Nassau-Oranien had come to Nassau-Diez. The counts of Nassau-Diez therefore called themselves Princes of Nassau-Orange. With this they combined all the lines of the Ottoman branch of the house of Nassau in one hand. Since 1747 the herreditars Stadtholders of the Netherlands and resided in The Hague. The Princes administered the princes by a German Cabinet. Since 1742 a central administration existed in Dillenburg. All the left-hand Rhine possessions were lost to France between 1795 and 1801. The house received as compensation in the course of the Reichsdeputationshauptschluss among other things the Hochstift Fulda, Dortmund, Corvey and other areas as Principality of Orange.

Duchy of Nassau

On 30.08.1806  Nassau-Usingen and Nassau-Weilburg where united to an overall state, the Duchy of Nassau. The residences were transferred from Usingen and Weilburg to Biebrich (1926 after Wiesbaden) to Biebrich Castle. In the same year, the two states joined the Rheinbund, where Friedrich August, as head of the House, received the Duke’s dignity and thus the Duchy of Nassau. For the loss of the parts of the Rhine (Saarbrücken) to France, the duchy was considerably compensated for. In 1813, and finally in the Congress of Vienna, the Principalities of Diez, Hadamar and Dillenburg were added. For the first time since 1255, all German Nassau countries – with the exception of Siegens – were once again united in one hand. Heir to the remaining Walrian lines – the Usinger and the Weilburg – was Wilhelm von Nassau-Weilburg, who became a regent of the Duchy as Wilhelm I.  The government seat was Wiesbaden, which had been a resident residence since 1734. Duke Adolph lost his country after the German War 1866 to Prussia.

After the House of Orange-Nassau became extinct in the Netherlands in the male line on 23.11.1890, Adolph became the Grand Duke of Luxembourg on the basis of an inheritance contract from 1783. As Grand Duke Weilhelm IV. had six daughters but no sons in 1907 an amendment was made to the House Law to allow his oldest daughter to succeed him as Grand Duchess. As a result of his marriage to the catholic Infanta Maria Anna of Portugal his daughters where raised in the catholic faith resulting in the fact that this line is no catholic. Grand Duchess Marie Adelaide had to abdicate on 15.01.1919 on the advice of Parliament and after enormous pressure from the Luxembourgish people because of her perceived support for the German occupation forces which had led to great unpopularity in Luxembourg as well as neighbouring France and Belgium. She was succeeded by her younger sister Charlotte who managed to save the monarchy. Although the walram line of the House of Nassau has become extinct in the male line her descendants continue to use the Name of Nassau and the Title Prince/Princess of Nassau for the junio members of the Family.
