William the Silent noble title Prince of Orange
William the Silent or William the Taciturn (Dutch: Willem de Zwijger; 24 April 1533 – 10 July 1584), more commonly known in the Netherlands as William of Orange (Dutch: Willem van Oranje), was the main leader of the Dutch revolt against the Spanish Habsburgs that set off the Eighty Years' War (1568–1648) and resulted in the formal independence of the United Provinces in 1648. Born into the House of Nassau, he became Prince of Orange in 1544 and is thereby the founder of the Orange-Nassau branch and the ancestor of the monarchy of the Netherlands. In the Netherlands, he is also known as Father of the Fatherland (Latin: Pater Patriae; Dutch: Vader des Vaderlands).
A wealthy nobleman, William originally served the Habsburgs as a member of the court of Margaret of Parma, governor of the Spanish Netherlands. Unhappy with the centralisation of political power away from the local estates and with the Spanish persecution of Dutch Protestants, William joined the Dutch uprising and turned against his former masters. The most influential and politically capable of the rebels, he led the Dutch to several successes in the fight against the Spanish. Declared an outlaw by the Spanish king in 1580, he was assassinated by Balthasar Gérard in Delft in 1584.Early life and education
William was born on 24 April 1533 at Dillenburg Castle in the County of Nassau-Dillenburg, in the Holy Roman Empire (now in Hesse, German Federal Republic). He was the eldest son of Count William I of Nassau-Siegen and Juliana of Stolberg. William's father had one surviving daughter by his previous marriage, and his mother had four surviving children by her previous marriage. His parents had twelve children together, of whom William was the eldest; he had four younger brothers and seven younger sisters. The family was religiously devout and William was raised a Lutheran.In 1544, William's agnatic first cousin, René of Châlon, Prince of Orange, died in the siege of St Dizier, childless. In his testament, René of Chalon named William the heir to all his estates and titles, including that of Prince of Orange, on the condition that he receive a Roman Catholic education. William's father acquiesced to this condition on behalf of his 11-year-old son, and this was the founding of the House of Orange-Nassau. Besides the Principality of Orange (located today in France) and significant lands in Germany, William also inherited vast estates in the Low Countries (present-day Netherlands and Belgium) from his cousin. Because of William's young age, Emperor Charles V, who was the overlord of most of these estates, served as regent until William was old enough to rule them himself.
William was sent to the Netherlands to receive the required Roman Catholic education, first at the family's estate in Breda and later in Brussels, under the supervision of the Emperor's sister Mary of Hungary, governor of the Habsburg Netherlands (Seventeen Provinces). In Brussels, he was taught foreign languages and received a military and diplomatic education under the direction of Jérôme Perrenot de Champagney, brother of Cardinal de Granvelle.
On 6 July 1551, William married Anna, daughter and heir of Maximiliaan van Egmond, an important Dutch nobleman, a match that had been secured by Charles V. Anna's father had died in 1548, and therefore William became Lord of Egmond and Count of Buren upon his wedding day. The marriage was a happy one and produced three children, one of whom died in infancy. Anna died on 24 March 1558, aged 25, leaving William much grieved.Legacy
Succession and family ties
Philip William, William's eldest son by his first marriage, to Anna of Egmond, succeeded him as the Prince of Orange.  However, as Philip William was a hostage in Spain and had been for most of his life, his brother Maurice of Nassau was appointed Stadholder and Captain-General at the suggestion of Johan van Oldenbarneveldt, and as a counterpoise to the Earl of Leicester. Phillip William died in Brussels on 20 February 1618 and was succeeded by his half-brother Maurice, the eldest son by William's second marriage, to Anna of Saxony, who became Prince of Orange. A strong military leader, he won several victories over the Spanish. Van Oldenbarneveldt managed to sign a very favourable twelve-year armistice in 1609, although Maurice was unhappy with this. Maurice was a heavy drinker and died on 23 April 1625 from liver disease.  Maurice had several sons by Margaretha van Mechelen, but he never married her. So, Frederick Henry, Maurice's half-brother (and William's youngest son from his fourth marriage, to Louise de Coligny) inherited the title of Prince of Orange. Frederick Henry continued the battle against the Spanish. Frederick Henry died on 14 March 1647 and is buried with his father William "The Silent" in Nieuwe Kerk, Delft. The Netherlands became formally independent after the Peace of Westphalia in 1648.
The son of Frederick Henry, William II of Orange succeeded his father as stadtholder, as did his son, William III of Orange. The latter also became king of England, Scotland and Ireland from 1689. Although he was married to Mary II, Queen of Scotland and England for 17 years, he died childless in 1702.  He appointed his cousin Johan Willem Friso (William's great-great-great-grandson) as his successor. Because Albertine Agnes, a daughter of Frederick Henry, married William Frederik of Nassau-Dietz, the present royal house of the Netherlands is descended from William the Silent through the female line. See House of Orange for a more extensive overview. As the chief financer and political and military leader of the early years of the Dutch revolt, William is considered a national hero in the Netherlands, even though he was born in Germany, and usually spoke French.
In the 19th century the Netherlands became a constitutional monarchy, currently with King Willem-Alexander as head of state: he has cognatic descent from William of Orange. All stadtholders after William of Orange were drawn from his descendants or the descendants of his brother.
