William the Silent William I , Prince of Orange ( 24 April 1533 – 10 July 1584 ) , also widely known as William the Silent ( ) , or simply William of Orange ( ) , was the main leader of the Dutch revolt against the Spanish that set off the Eighty Years ' War and resulted in the formal independence of the United Provinces in 1648 . He was born in the House of Nassau as Count of Nassau - Dillenburg . He became Prince of Orange in 1544 and is thereby the founder of the branch House of Orange - Nassau and the ancestor of the monarchy of the Netherlands . 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 ( also written as " Gerardts " ) in Delft four years later ( 1584 ) . Early life . William was born on 24 April 1533 in the castle of Dillenburg in the duchy of Nassau in the Holy Roman Empire , now in Hesse , Germany . He was the eldest son of William , Count of Nassau , and Juliana of Stolberg - Werningerode , and was raised a Lutheran . He had four younger brothers and seven younger sisters : John , Hermanna , Louis , Maria , Anna , Elisabeth , Katharine , Juliane , Magdalene , Adolf and Henry . When his cousin , René of Châlon , Prince of Orange , died childless in 1544 , the eleven - year - old William inherited all Châlon ' s property , including the title Prince of Orange , on the condition that he receive a Roman Catholic education . This was the founding of the house of Orange - Nassau . Besides Châlon ' s properties , he also inherited vast estates in the Low Countries ( present - day Netherlands and Belgium ) . Because of his young age , the Holy Roman Emperor Charles V served as the regent of the principality until William was fit to rule . William was sent to the Netherlands to receive the required education , first at the family ' s estate in Breda , later in Brussels under the supervision of Mary of Habsburg ( Mary of Hungary ) , the sister of Charles V and 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 Champagney ( Jérôme Perrenot ) , brother of Granvelle . On 6 July 1551 , he married Anna van Egmond en Buren , the wealthy heir to the lands of her father , and William gained the titles Lord of Egmond and Count of Buren . They had three children . Later that same year , William was appointed captain in the cavalry . Favoured by Charles V , he was rapidly promoted , and became commander of one of the Emperor ' s armies at the age of 22 . He was made a member of the Raad van State , the highest political advisory council in the Netherlands . It was in November 1555 , shortly after Charles had abdicated in favour of his son , Philip II of Spain that the gout - afflicted Emperor leaned on William ' s shoulder during his abdication ceremony . His wife Anna died on 24 March 1558 . Later , William had a brief relationship with Eva Elincx , leading to the birth of their illegitimate son , Justinus van Nassau : William officially recognised him and took responsibility for his education – Justinus would become an admiral in his later years . In 1559 , Philip appointed William as the stadtholder ( governor ) of the provinces Holland , Zeeland and Utrecht , thereby greatly increasing his political power . A stadtholdership over Franche - Comté followed in 1561 . From politician to rebel . Although he never directly opposed the Spanish king , William soon became one of the most prominent members of the opposition in the Council of State , together with Philip de Montmorency , Count of Hoorn , and Lamoral , Count of Egmont . They were mainly seeking more political power for themselves against the " de facto " government of Count Berlaymont , Granvelle and Viglius of Aytta , but also for the Dutch nobility and , ostensibly , for the Estates , and complained that too many Spaniards were involved in governing the Netherlands . William was also dissatisfied with the increasing persecution of Protestants in the Netherlands . Brought up as a Lutheran and later a Catholic , William was very religious but was still a proponent of freedom of religion for all people . The activity of the Inquisition in the Netherlands , directed by Cardinal Granvelle , prime minister to the new governor Margaret of Parma ( 1522 – 83 ) ( natural half - sister to Philip II ) , increased opposition to Spanish rule among the – then mostly Catholic – population of the Netherlands . Lastly , the opposition wished to see an end to the presence of Spanish troops . On 25 August 1561 , William of Orange married for the second time . His new wife , Anna of Saxony , was described by contemporaries as " self - absorbed , weak , assertive , and cruel " , and it is generally assumed that William married her to gain more influence in Saxony , Hesse and the Palatinate . The couple had five children . Up to 1564 , any criticism of governmental measures voiced by William and the other members of the opposition had ostensibly been directed at Granvelle ; however , after the latter ' s departure early that year , William , who may have found increasing confidence in his alliance with the Protestant princes of Germany following his second marriage , began to openly criticize the King ' s anti - Protestant politics . In an iconic speech to the Council of State , William to the shock of his audience justified his conflict with Philip by saying that , even though he had decided for himself to keep to the Catholic faith , he could not agree that monarchs should rule over the souls of their subjects and take from them their freedom of belief and religion . Later , in his " Apology " ( 1580 ) , William stated that his resolve to oppose the King ' s policies had originated in June 1559 . William and the Duke of Alva had been sent to France as hostages for the proper fulfillment of the Treaty of Cateau - Cambrésis following the Hispano - French war . During a hunting trip to the Bois de Vincennes with King Henry II of France , William and Alva had openly discussed a secret understanding between Philip and Henry which aimed at the extermination of the Protestants in both France and the Netherlands . William at that time had kept silent , but had decided for himself that he would not allow the slaughter of so many innocent subjects . In early 1565 , a large group of lesser noblemen , including William ' s younger brother Louis , formed the Confederacy of Noblemen . On 5 April , they offered a petition to Margaret of Parma , requesting an end to the persecution of Protestants . From August to October 1566 , a wave of iconoclasm ( known as the " Beeldenstorm " ) spread through the Low Countries . Calvinists ( the major Protestant denomination ) , Anabaptists , and Mennonites , angered by Catholic repression and theologically opposed to the Catholic use of images of saints ( which in their eyes conflicted with the Second Commandment ) , destroyed statues in hundreds of churches and monasteries throughout the Netherlands . Following the Beeldenstorm , unrest in the Netherlands grew , and Margaret agreed to grant the wishes of the Confederacy , provided the noblemen would help to restore order . She also allowed more important noblemen , including William of Orange , to assist the Confederacy . In late 1566 , and early 1567 , it became clear that she would not be allowed to fulfil her promises , and when several minor rebellions failed , many Calvinists and Lutherans fled the country . Following the announcement that Philip II , unhappy with the situation in the Netherlands , would dispatch his loyal general Fernando Álvarez de Toledo , Duke of Alba ( also known as " The Iron Duke " ) , to restore order , William laid down his functions and retreated to his native Nassau in April 1567 . He had been ( financially ) involved with several of the rebellions . After his arrival in August 1567 , Alba established the " Council of Troubles " ( known to the people as the " Council of Blood " ) to judge those involved in the rebellion and the iconoclasm . William was one of the 10 , 000 to be summoned before the Council , but he failed to appear . He was subsequently declared an outlaw , and his properties were confiscated . As one of the most prominent and popular politicians of the Netherlands , William of Orange emerged as the leader of armed resistance . He financed the " Watergeuzen " , refugee Protestants who formed bands of corsairs and raided the coastal cities of the Netherlands ( often killing Spanish and Dutch alike ) . He also raised an army , consisting mostly of German mercenaries , to fight Alba on land . William allied with the French Huguenots , following the end of the second Religious War in France when they had troops to spare . Led by his brother Louis , the army invaded the northern Netherlands in 1568 . However the plan failed almost from the start . The Huguenots were defeated by French royal troops before they could invade , and a small force under Jean de Villers was captured within two days . Villers gave all the plans of the campaign to the Spanish following his capture . On 23 May , the army under the command of Louis won the Battle of Heiligerlee in the northern province of Groningen against a Spanish army led by the stadtholder of the northern provinces , Jean de Ligne , Duke of Aremberg . Aremberg was killed in the battle , as was William ' s brother Adolf . Alba countered by killing a number of convicted noblemen ( including the Counts of Egmont and Hoorn on 6 June ) , and then by leading an expedition to Groningen . There , he annihilated Louis ’ forces on German territory in the Battle of Jemmingen on 21 July , although Louis managed to escape . These two battles are now considered to be the start of the Eighty Years ' War . War . In October 1568 , William responded by leading a large army into Brabant , but Alba carefully avoided a decisive confrontation , expecting the army to fall apart quickly . As William advanced , disorder broke out in his army , and with winter approaching and money running out , William turned back . William made several more plans to invade in the next few years , but little came of them , since he lacked support and money . He remained popular with the public , in part through an extensive propaganda campaign conducted through pamphlets . One of his most important claims , with which he attempted to justify his actions , was that he was not fighting the rightful ruler of the land , the King of Spain , but only the inadequate rule of the foreign governors in the Netherlands , and the presence of foreign soldiers . On 22 August 1571 , his second wife Anna gave birth to a daughter - named Christina von Dietz - fathered by Jan Rubens , best known as the father of painter Peter Paul Rubens ; Jan Rubens had been sent by her uncle in 1570 to manage her finances . Later that year , William had this marriage legally dissolved on the grounds that Anna was insane . On 1 April 1572 a band of Watergeuzen captured the city of Brielle , which had been left unattended by the Spanish garrison . Contrary to their normal " hit and run " tactics , they occupied the town and claimed it for the prince by raising the Prince of Orange ' s flag above the city . This event was followed by other cities opening their gates for the Watergeuzen , and soon most cities in Holland and Zeeland were in the hands of the rebels , notable exceptions being Amsterdam and Middelburg . The rebel cities then called a meeting of the " Staten Generaal " ( which they were technically unqualified to do ) , and reinstated William as the stadtholder of Holland and Zeeland . Concurrently , rebel armies captured cities throughout the entire country , from Deventer to Mons . William himself then advanced with his own army and marched into several cities in the south , including Roermond and Leuven . William had counted on intervention from the Huguenots as well , but this plan was thwarted after the St . Bartholomew ' s Day Massacre on 24 August , which signalled the start of a wave of violence against the Huguenots . After a successful Spanish attack on his army , William had to flee and he retreated to Enkhuizen , in Holland . The Spanish then organised countermeasures , and sacked several rebel cities , sometimes massacring their inhabitants , such as in Mechelen or Zutphen . They had more trouble with the cities in Holland , where they took Haarlem after seven months and a loss of 8 , 000 soldiers , and they had to break off their siege of Alkmaar . In 1573 , William joined the Calvinist Church . In 1574 , William ' s armies won several minor battles , including several naval encounters . The Spanish , led by Don Luis de Zúñiga y Requesens since Philip replaced Alba in 1573 , also had their successes . Their decisive victory in the Battle of Mookerheyde in the south east , on the Meuse embankment , on 14 April cost the lives of two of William ' s brothers , Louis and Henry . Requesens ' s armies also besieged the city of Leiden . They broke off their siege when nearby dykes were breached by the Dutch . William was very content with the victory , and established the University of Leiden , the first university in the Northern Provinces . William married for the third time on 24 April 1575 to Charlotte de Bourbon - Monpensier , a former French nun , who was also popular with the public . They had six daughters . The marriage , which seems to have been a love match on both sides , was happy . After failed peace negotiations in Breda in 1575 , the war continued . The situation improved for the rebels when Don Requesens died unexpectedly in March 1576 , and a large group of Spanish soldiers , not having received their salary in months , mutinied in November of that year and unleashed the Spanish Fury on the city of Antwerp , a tremendous propaganda coup for the rebels . While the new governor , Don John of Austria , was en route , William of Orange got most of the provinces and cities sign the Pacification of Ghent , in which they declared themselves ready to fight for the expulsion of Spanish troops together . However , he failed to achieve unity in matters of religion . Catholic cities and provinces would not allow freedom for Calvinists , and vice versa . When Don John signed the Perpetual Edict in February 1577 , promising to comply with the conditions of the Pacification of Ghent , it seemed that the war had been decided in favour of the rebels . However , after Don John took the city of Namur in 1577 , the uprising spread throughout the entire Netherlands . Don John attempted to negotiate peace , but the prince intentionally let the negotiations fail . On 24 September 1577 , he made his triumphal entry in the capital Brussels . At the same time , Calvinist rebels grew more radical , and attempted to forbid Catholicism in areas under their control . William was opposed to this both for personal and political reasons . He desired freedom of religion , and he also needed the support of the less radical Protestants and Catholics to reach his political goals . On 6 January 1579 , several southern provinces , unhappy with William ' s radical following , signed the Treaty of Arras , in which they agreed to accept their Catholic governor , Alessandro Farnese , Duke of Parma ( who had succeeded Don John ) . Five northern provinces , later followed by most cities in Brabant and Flanders , then signed the Union of Utrecht on 23 January , confirming their unity . William was initially opposed to the Union , as he still hoped to unite all provinces . Nevertheless , he formally gave his support on 3 May . The Union of Utrecht would later become a " de facto " constitution , and would remain the only formal connection between the Dutch provinces until 1795 . Declaration of Independence . In spite of the renewed union , the Duke of Parma was successful in reconquering most of the southern part of the Netherlands . Because he had agreed to remove the Spanish troops from the provinces under the Treaty of Arras , and because Philip II needed them elsewhere subsequently , the Duke of Parma was unable to advance any further until the end of 1581 . In the mean time , William and his supporters were looking for foreign support . The prince had already sought French assistance on several occasions , and this time he managed to gain the support of Francis , Duke of Anjou , brother of King Henry III of France . On 29 September 1580 , the Staten Generaal ( with the exception of Zeeland and Holland ) signed the Treaty of Plessis - les - Tours with the Duke of Anjou . The Duke would gain the title " Protector of the Liberty of the Netherlands " and become the new sovereign . This , however , required that the Staten Generaal and William renounce their formal support of the King of Spain , which they had maintained officially up to that moment . On 22 July 1581 , the Staten Generaal declared that they no longer recognised Philip II of Spain as their ruler , in the Act of Abjuration . This formal declaration of independence enabled the Duke of Anjou to come to the aid of the resisters . He did not arrive until 10 February 1582 , when he was officially welcomed by William in Flushing . On 18 March , the Spaniard Juan de Jáuregui attempted to assassinate William in Antwerp . Although William suffered severe injuries , he survived thanks to the care of his wife Charlotte and his sister Mary . While William slowly recovered , Charlotte became exhausted from providing intensive care , and died on 5 May . The Duke of Anjou was not very popular with the population . The provinces of Zeeland and Holland refused to recognise him as their sovereign , and William was widely criticised for what were called his " French politics " . When Anjou ' s French troops arrived in late 1582 , William ' s plan seemed to pay off , as even the Duke of Parma feared that the Dutch would now gain the upper hand . However , Anjou himself was displeased with his limited powers , and secretly decided to seize Antwerp by force . The citizens , who had been warned in time , ambushed Anjou and his troops as they entered the city on 18 January 1583 , in what is known as the " French Fury " . Almost all of Anjou ' s men were killed , and he was reprimanded from both Catherine de Medici and Elizabeth I of England ( whom he had courted ) . The position of Anjou after this attack became untenable , and he eventually left the country in June . His departure also discredited William , who nevertheless maintained his support for Anjou . He stood virtually alone on this issue , and became politically isolated . Holland and Zeeland nevertheless maintained him as their stadtholder , and attempted to declare him count of Holland and Zeeland , thus making him the official sovereign . In the middle of all this , William married for the fourth and final time on 12 April 1583 to Louise de Coligny , a French Huguenot and daughter of Gaspard de Coligny . She was to be the mother of Frederick Henry ( 1584 – 1647 ) , William ' s fourth legitimate son . Assassination . The Catholic Frenchman Balthasar Gérard ( born 1557 ) was a supporter of Philip II , and in his opinion , William of Orange had betrayed the Spanish king and the Catholic religion . After Philip II declared William an outlaw and promised a reward of 25 , 000 crowns for his assassination , and of which Gérard learned in 1581 , he decided to travel to the Netherlands to kill William . He served in the army of the governor of Luxembourg , Peter Ernst I von Mansfeld - Vorderort , for two years , hoping to get close to William when the armies met . This never happened , and Gérard left the army in 1584 . He went to the Duke of Parma to present his plans , but the Duke was unimpressed . In May 1584 , he presented himself to William as a French nobleman , and gave him the seal of the Count of Mansfelt . This seal would allow forgeries of the messages of Mansfelt to be made . William sent Gérard back to France to pass the seal on to his French allies . Gérard returned in July , having bought two wheel - lock pistols on his return voyage . On 10 July , he made an appointment with William of Orange in his home in Delft , nowadays known as the Prinsenhof . That day , William was having dinner with his guest Rombertus van Uylenburgh . After William left the dining room and walked down - stairs , Van Uylenburgh heard Gérard shoot William in the chest at close range . Gérard fled to collect his reward . According to official records , William ' s last words are said to have been : Gérard was caught before he could flee Delft , and imprisoned . He was tortured before his trial on 13 July , where he was sentenced to be brutally – even by the standards of that time – killed . The magistrates decreed that the right hand of Gérard should be burned off with a red - hot iron , that his flesh should be torn from his bones with pincers in six different places , that he should be quartered and disembowelled alive , that his heart should be torn from his bosom and flung in his face , and that , finally , his head should be cut off . Traditionally , members of the Nassau family were buried in Breda , but as that city was in Spanish hands when William died , he was buried in the New Church in Delft . His monument on his tomb was originally very modest , but it was replaced in 1623 by a new one , made by Hendrik de Keyser and his son Pieter . Since then , most of the members of the House of Orange - Nassau , including all Dutch monarchs , have been buried in the same church . His great - grandson William the third , King of England and Scotland and Stadtholder in the Netherlands , was buried in Westminster Abbey According to a British historian of science Lisa Jardine , he is reputed to be the first world head of state to be assassinated by handgun . The Scottish Regent Moray had been shot 13 years earlier , being the first recorded firearm assassination . Legacy . Philip William , William ' s eldest son by his first marriage , to Anna of Egmond , succeeded him as the Prince of Orange at the suggestion of Johan van Oldenbarneveldt . 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 . Many of the Dutch national symbols can be traced back to William of Orange : Other remembrances of William of Orange : Descended stadtholders and monarchs in the Netherlands . In the 19th century the Netherlands became a constitutional monarchy , currently with King Willem - Alexander as head of state : he is cognatically descended from William of Orange . All stadtholders after William of Orange where drawn from his descendants or the descendants of his brother . Epithet . There are several explanations for the origin of the style , " William the Silent " ( ) . The most common one relates to his prudence in regard to a conversation with the king of France . One day , during a stag - hunt in the Bois de Vincennes , Henry , finding himself alone with the Prince , began to speak of the great number of Protestant sectaries who , during the late war , had increased so much in his kingdom to his great sorrow . His conscience , said the King , would not be easy nor his realm secure until he could see it purged of the " accursed vermin , " who would one day overthrow his government , under the cover of religion , if they were allowed to get the upper hand . This was the more to be feared since some of the chief men in the kingdom , and even some princes of the blood , were on their side . But he hoped by the grace of God and the good understanding that he had with his new son , the King of Spain , that he would soon get the better of them . The King talked on thus to Orange in the full conviction that he was aware of the secret agreement recently made with the Duke of Alba for the extirpation of heresy . But the Prince , subtle and adroit as he was , answered the good King in such a way as to leave him still under the impression that he , the Prince , knew all about the scheme proposed by Alba ; and on this understanding the King revealed all the details of the plan which had been arranged between the King of Spain and himself for the rooting out and rigorous punishment of the heretics , from the lowest to the highest rank , and in this service the Spanish troops were to be mainly employed . Exactly when and by whom the nickname " the Silent " ( Modern Dutch : " " de Zwijger " " , meaning more " the Taciturn " . The verbs " " zwijgen " " in Dutch , " " schweigen " " in German , " " tiga " " in Swedish , " " se taire " " in French , " " callar / callarse " " in Spanish and " " tacere " " in Italian have no real equivalent in English ; they mean the opposite of " " to talk " " . ) was used for the first time is not known with certainty . It is traditionally ascribed to Cardinal de Granvelle , who is said to have referred to William as " the silent one " sometime during the troubles of 1567 . Both the nickname and the accompanying anecdote are first found in a historical source from the early 17th century . In the Netherlands , William is known as the " Vader des Vaderlands " , " Father of the Fatherland " , and the Dutch national anthem , the " Wilhelmus " , was written in his honour . Issue . Between his first and second marriages , William had an extramarital affair with Eva Elincx . They had a son , Justinus van Nassau ( 1559 – 1631 ) , whom William acknowledged . Coats of arms and Titles . A noble ' s power was often based on his ownership of vast tracts of land and lucrative offices . Besides being sovereign over the principality of Orange , William possessed these other estates , most enfoefed to some other sovereign , either the King of France or the Habsburgs : William used two sets of arms in his lifetime . The first one shown below was his ancestral arms of Nassau . The second arms he used most of his life from the time he became Prince of Orange on the death of his cousin René of Châlon . He placed the arms of Châlon - Arlay as princes of Orange as an inescutcheon on his father ' s arms . In 1582 , William purchased the marquisate of Veere and Vlissingen in Zeeland . It had been the property of Philip II since 1567 , but had fallen into arrears to the province . In 1580 , the Court of Holland ordered it sold . William bought it as it gave him two more votes in the States of Zeeland . He owned the government of the two towns , and so could appoint their magistrates . He already had one as First Noble for Philip William , who had inherited Maartensdijk . This made William the predominant member of the States of Zeeland . It was a smaller version of the countship of Zeeland ( and Holland ) promised to William , and was a potent political base for his descendants . William then added the shield of Veere and Buren to his arms as shown in the third coat of arms below . It shows how arms were used to represent political power in general , and the growing political power of William .
