House of Orange-Nassau

The House of Orange-Nassau (Dutch: Huis van Oranje-Nassau, pronounced [ˈɦœys fɑn oːˌrɑɲə ˈnɑsʌu]), also known as the House of Orange or rarely the Fourth House of Orange in comparison with the other noble houses that held the Principality of Orange, is the current reigning house of the Netherlands. A branch of the European House of Nassau, the house has played a central role in the politics and government of the Netherlands and elsewhere in Europe, particularly since William the Silent organised the Dutch Revolt against Spanish rule, which after the Eighty Years' War (1568–1648) led to an independent Dutch state. William III of Orange led the resistance of the Netherlands and Europe to Louis XIV of France and orchestrated the Glorious Revolution in England that established parliamentary rule. Similarly, Queen Wilhelmina of the Netherlands was instrumental in the Dutch resistance during World War II.

Several members of the house served during the Eighty Years war and after as stadtholder ("governor"; Dutch: stadhouder) during the Dutch Republic. However, in 1815, after a long period as a republic, the Netherlands became a monarchy under the House of Orange-Nassau.

The dynasty was established as a result of the marriage of Henry III of Nassau-Breda from Germany and Claudia of Chalon-Orange from French Burgundy in 1515. Their son René of Chalon inherited in 1530 the independent and sovereign Principality of Orange from his mother's brother, Philibert of Chalon. As the first Nassau to be the Prince of Orange, René could have used "Orange-Nassau" as his new family name. However, his uncle, in his will, had stipulated that René should continue the use of the name Chalon-Orange. After René's death in 1544, his cousin William of Nassau-Dillenburg inherited all of his lands. This "William I of Orange", in English better known as William the Silent, became the founder of the House of Orange-Nassau.

Nassau Castle was founded around 1100 by Dudo, Count of Laurenburg, the founder of the House of Nassau. In 1120, Dudo's sons and successors, Counts Rupert I and Arnold I, established themselves at Nassau Castle, taking for themselves the title "Count of Nassau". In 1255 the Nassau possessions were split between Walram and Otto, the sons of Count Henry II. The descendants of Walram were known as the Walram Line, and they became Dukes of Nassau and, in 1890, Grand Dukes of Luxembourg. This line also included Adolph of Nassau, who was elected King of the Romans in 1292. The descendants of Otto became known as the Ottonian Line, and they inherited parts of the County of Nassau, as well as properties in France and the Netherlands.^{[citation needed]}

The House of Orange-Nassau stems from the younger Ottonian Line. The first of this line to establish himself in the Netherlands was John I, Count of Nassau-Siegen, who married Margaret of the Mark. The real founder of the Nassau fortunes in the Netherlands was John's son, Engelbert I. He became counsellor to the Burgundian Dukes of Brabant, first to Anton of Burgundy, and later to his son Jan IV of Brabant. He also would later serve Philip the Good. In 1403, he married the Dutch noblewoman Johanna van Polanen and so inherited lands in the Netherlands, with the Barony of Breda as the core of the Dutch possessions and the family fortune.

A nobleman's power was often based on his ownership of vast tracts of land and lucrative offices. It also helped that much of the lands that the House of Orange-Nassau controlled sat under one of the commercial and mercantile centres of the world (see below under Lands and Titles). The importance of the family grew throughout the 15th and 16th centuries as they became councilors, generals and stadholders of the Habsburgs (see armorial of the great nobles of the Burgundian Netherlands and list of knights of the Golden Fleece). Engelbert II of Nassau served Charles the Bold and Maximilian I, Holy Roman Emperor, who had married Charles's daughter Mary of Burgundy. In 1496, he was appointed stadtholder of Flanders and by 1498 he had been named President of the Grand Conseil. In 1501, Maximilian named him Lieutenant-General of the Seventeen Provinces of the Netherlands. From that point forward (until his death in 1504), Engelbert was the principal representative of the Habsburg Empire to the region. Hendrik III of Nassau-Breda was appointed stadtholder of Holland and Zeeland by Charles of Ghent in the beginning of the 16th century. Hendrik was succeeded by his son René of Chalon in 1538, who had inherited the title of Prince of Orange and the principality of that name from his maternal uncle Philibert of Chalon. In 1544, René died in battle aged 25. His possessions, including the principality and title, passed by his will as sovereign prince to his paternal cousin, William I of Orange. From then on, the family members called themselves "Orange-Nassau."

Although Charles V pretended to resist the Protestant Reformation, he ruled the Dutch territories wisely with moderation and regard for local customs, and he did not persecute his Protestant subjects on a large scale. His son Philip II inherited his antipathy for the Protestants but not his moderation. Under the reign of Philip, a true persecution of Protestants was initiated and taxes were raised to an outrageous level. Discontent arose and William of Orange (with his vague Lutheran childhood) stood up for the Protestant (mainly Calvinist) inhabitants of the Netherlands. Things went badly after the Eighty Years' War started in 1568, but luck turned to his advantage when Protestant rebels attacking from the North Sea captured Brielle, a coastal town in present-day South Holland in 1572. Many cities in Holland began to support William. During the 1570s he had to defend his core territories in Holland several times, but in the 1580s the inland cities in Holland were secure. William of Orange was considered a threat to Spanish rule in the area and was assassinated in 1584 by a hired killer sent by Philip.

William was succeeded by his second son Maurits, a Protestant who proved an excellent military commander. His abilities as a commander and the lack of strong leadership in Spain after the death of Philip II (1598) gave Maurits excellent opportunities to conquer large parts of the present-day Dutch territory. In 1585 Maurits was elected stadtholder of the provinces of Holland and Zealand as his father's successor and as a counterpose to Elizabeth's delegate, the Earl of Leicester. In 1587 he was appointed captain-general (military commander-in-chief) of the armies of the Dutch Republic. In the early years of the 17th century, there arose quarrels between stadtholder and oligarchist regents—a group of powerful merchants led by Johan van Oldebarnevelt—because Maurits wanted more powers in the Republic. Maurits won this power struggle by arranging the judicial murder of Oldebarnevelt.
