The United Kingdom of the Netherlands (Dutch: Verenigd Koninkrijk der Nederlanden, French: Royaume uni des Pays-Bas) 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. The polity was a constitutional monarchy, ruled by William I of the House of Orange-Nassau.

The polity collapsed in 1830 with the outbreak of the Belgian Revolution. With the de facto secession of Belgium, the Netherlands was left as a rump state and refused to recognise Belgian independence until 1839 when Treaty of London was signed, fixing the border between the two states and guaranteeing Belgian independence.


Before the French Revolutionary Wars (1792-1802), the Low Countries was a patchwork of different polities created by the Eighty Years' War (1568-1648). The Dutch Republic in the north was independent, while the Southern Netherlands was split between the Austrian Netherlands and Prince-Bishopric of Liège. The former was part of Habsburg Austria and both were part of the Holy Roman Empire. In the aftermath of the French Revolution, the War of the First Coalition broke out in 1792 and France was invaded by Prussia and the Holy Roman Empire. After two years of fighting, the Austrian Netherlands and Liège were captured by the French in 1794 and annexed into France. The Dutch Republic collapsed in 1795 and became a French puppet state.

Creation of the United Netherlands

In 1813, the Netherlands was liberated from French rule by Prussian and Russian troops during the Napoleonic Wars. The son of the last Dutch stadhouder, William Frederik of Orange-Nassau (the future King William I), was installed as the "sovereign prince" of a new Sovereign Principality of the United Netherlands. The future of the Southern Netherlands, however, was less clear. In June 1814, the Great Powers secretly agreed to the Eight Articles of London which allocated the region to the Dutch as William had advocated.

Discussions on the future of the region were still ongoing at the Congress of Vienna when Napoleon attempted return to power in the "Hundred Days". William used the occasion to declare himself king on 16 March 1815. After the Battle of Waterloo, discussions continued.

In exchange for the Southern Netherlands, William agreed to cede the Principality of Orange-Nassau and parts of the Liège to Prussia on 31 May 1815. In exchance, William also gained control over the Duchy of Luxembourg was elevated a grand duchy and placed in personal and political union with the Netherlands, though it remained part of the German Confederation.


Constitution and government

Though a constitutional monarchy, the king retained significant control in the United Netherlands as head of state and head of government. Beneath the king was a bicameral legislature known as the States General with a Senate and House of Representatives. From the start, the administrative system proved controversial. Representation in the 110-seat House of Representatives, for example, was divided equally between Southern and Northern Netherlands, although the former had a larger population. This was resented in the south, which believed that the government was dominated by the Dutch.

The United Netherlands was divided into 17 provinces and the Grand Duchy of Luxembourg which was constitutionally distinct. Many were based on the pre-existing départements, established by the French. They included:

The United Netherlands was also a colonial power with overseas colonies in the East Indies and elsewhere.

Economic policy

Economically, the United Netherlands prospered. Supported by the state, the Industrial Revolution began to affect the Southern Netherlands where a number of modern industries emerged, encouraged by figures such as John Cockerill who created the steel industry in Wallonia. Antwerp emerged as major trading port.

William I actively supported economic modernisation. Modern universities were established at Leuven, Liège, and Ghent in 1817. Lower education was also extended. The General Netherlands Society for Advancing National Industry (Algemeene Nederlandsche Maatschappij ter Begunstiging van de Volksvlijt) was created in 1822 to encourage industrialisation in the south, while the Netherlands Trading Society (Nederlandsche Handel-Maatschappij) was created in 1825 to encourage trade with the colonies. William I also embarked on a programme of canal building that saw the creation of the North Holland, Ghent–Terneuzen and Brussels–Charleroi canals.

Regional tensions

Differences between Southern and Northern Netherlands were never totally effaced. The two were divided by the issue of religion because the south was strongly Catholic and the north largely Protestant. The Church in Belgium resented the state's encroachment on its traditional privileges, especially in education. In French-speaking parts of the south, attempts to enforce the use of Dutch language were particularly resented among the elite. Many Belgians believed that the United Netherlands' constitution discriminated against them. Though they represented 62 percent of the population, they were only allocated 50 percent of the seats in the House and less in the Senate while the state extracted money from the richer south to subsidise the north. By the mid-1820s, a union of opposition had formed in Belgium, uniting liberals and Catholic conservatives against Dutch rule.

Belgian Revolution and secession

Fighting between Belgian rebels and the Dutch military expedition in Brussels in September 1830

The Belgian Revolution broke out on 25 August 1830, inspired by the recent July Revolution in France. A military intervention in September failed to defeat the rebels in Brussels, radicalising the movement. Belgium was declared an independent state on 4 October 1830. A constitutional monarchy was established under King Stanislaus III Albert (who was under the name as Stanislaus) an Polish King and Grand Duke of Lithuania.

William I refused to accept the secession of Belgium. In August 1831, he launched the Ten Days' Campaign, a major military offensive into Belgium. Though initially successful, the French intervened to support the Belgians and the invasion had to be abandoned. After a period of tension, a settlement was agreed at the Treaty of London in 1839. The Dutch recognised Belgian independence, in exchange for territorial concessions. The frontier between the two countries was finally fixed by the Treaty of Maastricht. Luxembourg became an autonomous state in personal union with the Dutch, though ceding some territory to Belgium.
