William the Silent or William the Taciturn, more commonly known in the Netherlands as William of Orange, was the 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.
Maurice of Orange was stadtholder of all the provinces of the Dutch Republic except for Friesland from 1585 at the earliest until his death in 1625. Before he became Prince of Orange upon the death of his eldest half-brother Philip William in 1618, he was known as Maurice of Nassau.
The Battle of Nieuwpoort, was fought on 2 July 1600 during the Eighty Years War and the Anglo-Spanish war in the dunes near Nieuwpoort. The Anglo-Dutch companies met the Spanish veterans head which, although their left flank nearly broke, were able to assail them with both infantry and cavalry. The Spanish gradually scattered in all directions and left their guns on the field.
The Battle of Fleurus, fought on 1 July 1690 near Fleurus, then part of the Spanish Netherlands, now in modern Belgium, was a major engagement of the Nine Years' War. A French army led by Marshall Luxembourg defeated an Allied force under Waldeck.
The Battle of Rocroi, fought on 19 May 1643, was a major engagement of the Thirty Years' War between a French army, led by the 21-year-old Duke of Enghien and Spanish forces under General Francisco de Melo only five days after the accession of Louis XIV to the throne of France after his father's death. Rocroi shattered the myth of invincibility of the Spanish Tercios, the terrifying infantry units that had dominated European battlefields for the previous 120 years. The battle is therefore often considered to mark the end of Spanish military greatness and the beginning of French hegemony in Europe during the 17th century. After Rocroi, the Spanish progressively transformed the tercio system incorporating more of the line infantry doctrine used by the French over time.
Luis de Requesens y Zúñiga was a Spanish general, sailor, diplomat and politician. He served as governor of the Duchy of Milan (1572–1573) and as governor of the Spanish Netherlands (1573–1576).

The siege of Leiden occurred during the Eighty Years' War and the Anglo–Spanish War in 1573 and 1574, when the Spanish under Francisco de Valdez attempted to capture the rebellious city of Leiden, South Holland, the Netherlands. The siege failed when the city was successfully relieved in October 1574.
The Battle of Zutphen was fought on 22 September 1586, near the village of Warnsveld and the town of Zutphen, the Netherlands, during the Eighty Years' War. It was fought between the forces of the United Provinces of the Netherlands, aided by the English, against the Spanish. In 1585, England signed the Treaty of Nonsuch with the States-General of the Netherlands and formally entered the war against Spain. Robert Dudley, Earl of Leicester, was appointed as the Governor-General of the Netherlands and sent there in command of an English army to support the Dutch rebels. When Alessandro Farnese, Duke of Parma and commander of the Spanish Army of Flanders, besieged the town of Rheinberg during the Cologne War, Leicester, in turn, besieged the town of Zutphen, in the province of Gelderland and on the eastern bank of the river IJssel.
The Battle of Kallo was a major field battle fought from 20 to 21 June 1638 in and around the forts of Kallo and Verrebroek, located on the left bank of the Scheldt river, near Antwerp, during the second phase of the Eighty Years' War. Following the symbolic recovery of Breda during the 1637 campaign, the Dutch Republic agreed with the French Crown, with whom it had allied in 1635, to besiege a major city in the Spanish Netherlands during the 1638 campaign. The commander of the Dutch States Army, Frederick Henry of Orange, planned an approach over Antwerp from the two sides of the Scheldt. After marching the army, Frederick Henry transferred 50 barges to Count William of Nassau-Siegen and he was left entrusted to land in the Spanish-controlled Waasland region, west of Antwerp, to seize the forts of Kallo and Verrebroek, along with several other key fortifications, to invest Antwerp from the west. In the meantime, Frederick Henry would advance on the opposite bank to complete the blockade of the city while the armies of France invaded the Spanish Netherlands from the south to oblige the Spanish Army of Flanders to divide its forces.
The Battle of Dahlen was fought on April 23, 1568, between a Dutch rebel army led by Jean de Montigny, Lord of Villers, and a Spanish army commanded by Sancho Dávila y Daza. As a part of William of Orange's planned invasion, the Dutch rebels were trying to conquer the town of Roermond when the arrival of the Spanish force compelled them to withdraw. Dávila pursued the retreating force and inflicted a defeat upon Villers near the small town of Dahlen. The survivors of this encounter sought refuge under the walls of Dahlen, where the Spanish infantry finally defeated them. This battle is sometimes considered the official start of the Eighty Years' War.
Philip of Nassau or Filips of Nassau was a Count of Nassau, Katzenelnbogen, Vianden and Dietz, fought for the United Provinces during the Eighty Years' War. He was the son of John VI and Countess Elisabeth of Leuchtenberg.
The Army of Flanders was a multinational army in the service of the kings of Spain that was based in the Spanish Netherlands during the 16th to 18th centuries. It was notable for being the longest-serving army of the period, being in continuous service from 1567 until its disestablishment in 1706 and taking part in numerous pivotal battles of the Dutch Revolt (1566–1609) and the Thirty Years' War (1618–1648). Because it employed or pioneered many developing military concepts more reminiscent of later military units, enjoying permanent, standing regiments (tercios), barracks, military hospitals and rest homes long before they were adopted in most of Europe, the Army of Flanders has been considered the world's de facto first modern professional standing army. Sustained at huge cost and at significant distances from Spain via the Spanish Road, the Army of Flanders also became infamous for successive mutinies and its ill-disciplined activity on and off the battlefield, including the Sack of Antwerp in 1576.
The Battle of the Lippe was a cavalry action fought on 2 September 1595 on the banks of the Lippe river, in Germany, between a corps of Spanish cavalry led by Juan de Córdoba and a corps of Dutch cavalry, supported by English troops, led by Philip of Nassau. The Dutch stadtholder Maurice of Nassau, taking advantage of the fact that the bulk of the Spanish army was busied in operations in France, besieged the town of Groenlo in Gelderland, but the elderly governor of the citadel of Antwerp, Cristóbal de Mondragón, organized a relief army and forced Maurice to lift the siege. Mondragón next moved to Wesel, positioning his troops on the southern bank of the Lippe river to cover Rheinberg from a Dutch attack. Maurice aimed then, relying on his superior army, to entice Mondragón into a pitched battle, planning to use an ambush to draw the Spanish army into a trap. However, the plan was discovered by the Spanish commander, who organized a counter-ambush.
The siege of Mons of 1572 took place at Mons, capital of the County of Hainaut, Spanish Netherlands, between 23 June and 19 September 1572, as part of the Eighty Years' War, the Anglo-Spanish War (1585–1604), and the French Wars of Religion. In the spring of 1572, after the capture of Valenciennes by a Protestant force under Louis of Nassau, the Dutch commander continued with his offensive and took Mons by surprise on 24 May. After three months of siege, and the defeats of the armies of Jean de Hangest, seigneur d'Yvoy and Genlis, and William the Silent, Prince of Orange (Dutch: Willem van Oranje), by the Spanish army led by Don Fernando Álvarez de Toledo, Duke of Alba, Governor-General of the Spanish Netherlands, and his son, Don Fadrique de Toledo, Louis of Nassau's forces, isolated and without any hope of help, surrendered Mons to the Duke of Alba on 19 September.
The siege of Rheinberg took place from the 9 to 19 August 1597 during the Eighty Years' War and the Anglo–Spanish War by a Dutch and English army led by Maurice of Orange. The siege ended with the capitulation and the withdrawal of the Spanish after much unrest in the garrison. The liberation of the city of Rheinberg was the commencement of Maurice's campaign of 1597, a successful offensive against the Spaniards during the period known as the Ten Glory Years.
The Capture of Valkenburg of 1574, took place in early February 1574, at Valkenburg, South Holland, during the Eighty Years' War and the Anglo-Spanish War (1585–1604), in the context of the siege of Leiden. The fortress of Valkenburg, garrisoned by five English companies commanded by Colonel Edward Chester, was of strategic importance to facilitate the Spanish efforts at Leiden. In early February, when the Spanish troops advanced over Valkenburg Castle, the English troops surrendered the fortress to the Spaniards and fled towards Leiden. Then, the Spanish forces entered and took possession of the fortress. For the cowardice demonstrated at Valkenburg, the English troops were rejected by the Dutch rebel army at Leiden, and finally Chester's troops surrendered to the Spanish army.
The siege of Coevorden was a siege that took place between 26 July and 2 September 1592 during the Eighty Years' War and the Anglo–Spanish War at the city of Coevorden by a Dutch and English force under overall command of Maurice of Nassau. The city was defended by Frederik van den Bergh who had been commissioned for the defence by King Philip II of Spain.
The period between the Capture of Brielle and the Pacification of Ghent was an early stage of the Eighty Years' War between the Spanish Empire and groups of rebels in the Habsburg Netherlands.
