William I was King of the Netherlands and Grand Duke of Luxembourg from 1815 until his abdication in 1840.
The United Kingdom of the Netherlands is the unofficial name given to the Kingdom of the Netherlands as it existed between 1815 and 1830. The United Netherlands was created in the aftermath of the Napoleonic Wars through the fusion of territories that had belonged to the former Dutch Republic, Austrian Netherlands, and Prince-Bishopric of Liège in order to form a buffer state between the major European powers. The polity was a constitutional monarchy, ruled by William I of the House of Orange-Nassau.
Leopold I was the first king of the Belgians, reigning from 21 July 1831 until his death in 1865.
William the Silent or William the Taciturn, more commonly known in the Netherlands as William of Orange, 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.
The Eighty Years' War or Dutch Revolt was an armed conflict in the Habsburg Netherlands between disparate groups of rebels and the Spanish government. The causes of the war included the Reformation, centralisation, taxation, and the rights and privileges of the nobility and cities.
The Belgian Revolution was the conflict which led to the secession of the southern provinces from the United Kingdom of the Netherlands and the establishment of an independent Kingdom of Belgium.
The Battle of Jodoigne, also called Battle of the River Guete, was fought on 20 October 1568 between the royal Habsburg army led by the Duke of Alba and a Protestant rebel army led by William of Orange. It resulted in a defeat for William of Orange, who had to abandon his plans of invading the Habsburg Netherlands.
The ten days' campaign was a failed military expedition by the United Kingdom of the Netherlands against the secessionist Kingdom of Belgium between 2 and 12 August 1831. The campaign was an attempt by the Dutch King William I to halt the course of the Belgian Revolution which had broken out in August 1830.
Prince Frederick of the Netherlands, Prince of Orange-Nassau, was the second son of William I of the Netherlands and his wife, Wilhelmine of Prussia.
The Brabant Revolution or Brabantine Revolution, sometimes referred to as the Belgian Revolution of 1789–1790 in older writing, was an armed insurrection that occurred in the Austrian Netherlands between October 1789 and December 1790. The revolution, which occurred at the same time as revolutions in France and Liège, led to the brief overthrow of Habsburg rule and the proclamation of a short-lived polity, the United Belgian States.
Jonkheer Albert Dominicus Trip van Zoudtlandt was a Dutch lieutenant-general of cavalry who headed the Dutch heavy cavalry brigade at the Battle of Waterloo.
Jean Victor de Constant Rebecque was a Swiss mercenary who distinguished himself in Dutch service. As chief-of-staff of the Netherlands Mobile Army he countermanded the order of the Duke of Wellington to evacuate Dutch troops from Quatre Bras on the eve of the Battle of Quatre Bras, thereby preventing Marshal Michel Ney from occupying that strategic crossroads.
The Low Countries theatre of the War of the First Coalition, in British historiography better known as the Flanders campaign, was a series of campaigns in the Low Countries conducted from 20 April 1792 to 7 June 1795 during the first years of the War of the First Coalition. As the French Revolution radicalised, the revolutionary National Convention and its predecessors broke the Catholic Church's power (1790), abolished the monarchy (1792) and even executed the deposed king Louis XVI of France (1793), vying to spread the Revolution beyond the new French Republic's borders, by violent means if necessary. The First Coalition, an alliance of reactionary states representing the Ancien Régime in Central and Western Europe – Habsburg Austria, Prussia, Great Britain, the Dutch Republic, Hanover and Hesse-Kassel – mobilised military forces along all the French frontiers, threatening to invade Revolutionary France and violently restore the monarchy. The subsequent combat operations along the French borders with the Low Countries and Germany became the primary theatre of the War of the First Coalition until March 1796, when Napoleon took over French command on the Italian front.
The Battle of Les Avins or Avein took place on 20 May 1635, outside the town of Les Avins, near Huy in modern Belgium, then part of the Bishopric of Liège. It was the first major engagement of the 1635 to 1659 Franco-Spanish War, a connected conflict of the Thirty Years' War.
William II was King of the Netherlands, Grand Duke of Luxembourg, and Duke of Limburg.
The siege of Leuven was an important siege in the Thirty Years' War in which a Franco-Dutch army under Frederick Henry of Orange and the French Marshals Urbain de Maillé-Brezé and Gaspard III de Coligny, who had invaded the Spanish Netherlands from two sides, laid siege to the city of Leuven, defended by a force of 4,000 comprising local citizen and student militias with Walloons, Germans, Spanish and Irish of the Army of Flanders under Anthonie Schetz, Baron of Grobbendonck. Poor organization and logistics and the spread of sickness among the French, along with the appearance of an Imperial-Spanish relief army of 11,000 under Cardinal-Infante Ferdinand and Ottavio Piccolomini, forced the invading army to lift the siege. This failure allowed the Spanish forces to take the initiative and soon the invaders were forced into a headlong retreat.
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.
In the history of Belgium, the period from 1789 to 1914, dubbed the "long 19th century" by the historian Eric Hobsbawm, includes the end of Austrian rule and periods of French and Dutch rule over the region, leading to the creation of the first independent Belgian state in 1830.
The Battle of Borgerhout was a battle during the Eighty Years' War, of the Spanish Army of Flanders led by Alexander Farnese, Prince of Parma, upon a fortified camp at the village of Borgerhout, near Antwerp, where several thousand French, English, Scottish, and Walloon soldiers in service of the recently created Union of Utrecht were stationed. It took place during the reconquest by the armies of Philip II of Spain of the Burgundian Netherlands, whose different provinces had united in 1576 under the Pacification of Ghent to drive out the foreign troops and to grant religious liberty to Protestants.
The years 1621–1648 constituted the final phase of the Eighty Years' War between the Spanish Empire and the emerging Dutch Republic. It began when the Twelve Years' Truce (1609–1621) expired, and concluded with the Peace of Münster in 1648.
