🇧🇪 Belgium

Caesar recorded the Belgae as inhabiting northern Gaul from the Seine and Marne to the Rhine, describing them as the bravest of the Gauls. His conquest brought the region under Roman rule and gave the future nation its name.

After Caesar's conquests Gallia Belgica became the Latin name for a large province covering most of Northern Gaul, including the lands of the Belgae and Treveri. It was later divided, with eastern areas attached to the frontier province of Germania Inferior.

As Western Roman authority collapsed, Germanic-speaking Franks came to dominate the military and political spheres of Belgica and Germania. The Merovingians established a kingdom over the Romanised population and then conquered the other Frankish kingdoms.

The empire of the Franks came to be ruled by the Carolingians, whose heartland included what is now eastern Belgium. This placed the region at the political core of western Europe.

The treaty divided the empire into three kingdoms whose borders shaped medieval political boundaries for centuries. Most of modern Belgium fell into the Middle Kingdom, later Lotharingia, while the county of Flanders west of the Scheldt became the northernmost part of West Francia.

The treaty briefly placed all the lands of modern Belgium within the western kingdom. The arrangement proved temporary.

Lotharingia passed into the lasting control of the eastern kingdom, which eventually became the Holy Roman Empire. This entrenched a long-term frontier running through the Belgian lands between the French and imperial spheres.

The cloth industry and trade boomed, especially in Flanders, generating exceptional urban wealth. This prosperity also fuelled conflict with the king of France.

Infantry militias scored a surprise victory over a strong force of mounted knights. France soon regained control of the rebellious province, but the battle became a defining episode of Flemish identity.

Burgundy took control of Flanders and from there united much of present-day Benelux. The union brought economic and political stability, greater prosperity and artistic creation, and was the direct predecessor of the Austrian Netherlands and modern Belgium.

Charles gave the Seventeen Provinces legitimacy as a stable entity rather than a temporary personal union. He also extended their influence over the semi-independent Prince-Bishopric of Liège.

Revolt triggered by Spanish policy towards Protestantism led the northern United Provinces to separate from the Southern Netherlands. The southern part, comprising most of modern Belgium, remained under Spanish and later Austrian Habsburg rule.

The Franco-Dutch War, Nine Years' War, War of the Spanish Succession and War of the Austrian Succession were fought partly on Belgian soil. Repeated contestation by European powers earned the region its reputation as the Battlefield of Europe.

Following the campaigns of the French Revolutionary Wars, the Low Countries including the Prince-Bishopric of Liège were annexed to France. Two decades of French administration reshaped law and institutions, leaving a Napoleonic Code legacy.

Mining and steelmaking developed rapidly in Liège Province and around Charleroi, flourishing in the Sambre and Meuse valley. This made Belgium one of the three most industrialised nations in the world from 1830 to 1910.

After Napoleon's defeat at Waterloo, the powers united the former Dutch Republic, Austrian Netherlands and Prince-Bishopric of Liège under King William I of Orange. The buffer state placed the Belgian provinces under Dutch rule for fifteen years.

The uprising began in Brussels in August 1830 and led to a formal declaration of independence that October. A national congress adopted a constitution and installed Leopold I as king in 1831, and the major European powers recognised the new state's independence and neutrality in 1839.

His accession on 21 July 1831, now the National Day, established Belgium as a constitutional monarchy and parliamentary democracy with a laicist constitution based on the Napoleonic Code. The date anchors Belgian statehood.

The franc served as Belgium's currency from 1832 until 2002. Its long life spanned industrialisation, empire and both world wars.

The Flemish textile industry entered severe crisis in the 1840s and the region experienced famine between 1846 and 1850. The disaster deepened the economic divergence between an industrialising Wallonia and an impoverished north.

The Belgian instrument maker patented a new family of wind instruments. It became one of the country's most widely recognised technical contributions to music.

The chemist Solvay and the engineer Gramme gave their names to an industrial soda process and to a practical dynamo. Both underpinned Belgium's standing in chemicals and electrical engineering.

Leopold II received the vast Congo territory as his private possession. It became a source of ivory and rubber revenue extracted through extreme and savage treatment of the Congolese population.

The general strike of 1893 forced an extension of the franchise to all men, though plural voting persisted until 1919. Women received the vote only in 1949.

After decades in which French dominated public life, Dutch recovered official status. The step began a long process of linguistic rebalancing culminating in a Dutch version of the Constitution in 1967.

The Belgian chemist created the first fully synthetic plastic. It became a foundational material of the twentieth-century industrial economy.

King Leopold II had ruled the territory as his personal possession since 1885, a period marked by forced labour and mass deaths documented by international observers. The Belgian state took direct control in 1908, governing it as the Belgian Congo until 1960.

The series of invited conferences began in Brussels in 1911. They had a deep impact on the evolution of quantum physics and chemistry and gave Belgium lasting scientific prestige.

Jules Bordet (1919), Corneille Heymans (1938), Albert Claude and Christian de Duve (1974) won in physiology or medicine, Ilya Prigogine in chemistry (1977) and François Englert in physics (2013); Maurice Maeterlinck won the literature prize in 1911. Fields Medals went to Pierre Deligne in 1978 and Jean Bourgain in 1994.

The invasion began on 4 August 1914 as German forces advanced toward France, resulting in the destruction of Louvain and other attacks on civilians. Much of the Western Front's trench warfare, including at Ypres, was fought on Belgian soil.

The Games were held in Antwerp shortly after the First World War. It remains Belgium's principal hosting of a global sporting event.

The two countries became a single trade market with customs and currency union. It was an early template for later Benelux and European integration.

Belgium had seized the German colonies during the war and received them formally as a mandate. This extended the Belgian empire in central Africa alongside the Congo.

The former Prussian districts were incorporated after the First World War. This created the German-speaking minority that later became a constitutionally recognised Community.

The Catholic University of Louvain physicist advanced the theory of the origin of the universe. It stands as Belgium's major contribution to fundamental science.

The invasion began on 10 May 1940, and the occupation included the deportation of most of the country's Jewish population; some 40,690 Belgians, over half of them Jews, were killed during the occupation and the Holocaust. Allied forces liberated Brussels in September 1944, though fighting continued in the Ardennes into early 1945, with liberation complete by February 1945.

Belgium signed the Treaty of Brussels in March 1948 and became a founding member of NATO the same year. It abandoned neutrality for permanent Western alliance membership and later hosted major allied institutions.

The country pledged to eliminate net greenhouse gas emissions by mid-century. In 2023 Belgium emitted 106.82 million tonnes of greenhouse gases, about 9.12 tonnes per person.

Announced on 7 August 2026, the deployment of soldiers from the 1st Brigade and special forces runs from 4 to 18 September and aims to reinforce the alliance's presence in the Arctic amid US interest in Greenland and growing Russian and Chinese activity in the region.

The operation on 1 March 2026 was carried out with French naval assistance, targeting vessels believed to help Russia evade sanctions on oil exports. It followed a series of drone sightings over Belgian and Dutch military and transport infrastructure.

The ruling on 17 March 2026 covered charges of participation in war crimes linked to Lumumba's killing during Congo's post-independence crisis. Davignon, the last surviving individual accused by Lumumba's family, died in May 2026 before the case could conclude.

The deal, announced on 12 February 2026, followed three failed attempts to form a government since the June 2024 regional elections. It commits the region to a balanced budget by 2029 and a one-percentage-point cut in personal income tax.

The Peppol digital invoicing system became compulsory at the start of 2026 after a transition period. By August, around 1.06 million businesses, or 89 per cent of VAT-registered companies, had connected to the network, though the self-employed body Unizo said many firms had yet to see promised efficiency gains.

The raids on 2 December 2025 targeted the College of Europe in Bruges and the European External Action Service headquarters in Brussels, over the awarding of a tender for a European Diplomatic Academy training programme.

The demonstration on 18 December 2025 drew farmers from across the European Union objecting to the association agreement between the EU and the Mercosur bloc of South American countries, which they said would expose them to unfair competition.

The move, announced on 23 December 2025, followed the government's recognition of Palestinian statehood and sanctions on Israeli settlement goods earlier in the year, adding Belgium to a group of states formally intervening in the proceedings.

The sightings on 1 to 2 November 2025 were followed by further drone activity around Belgian military and transport sites in the weeks that followed, echoing similar incidents reported elsewhere in northern Europe.

The announcement on 2 September 2025 included a ban on products from Israeli settlements and restrictions on related public contracts, with the government setting out conditions for formal recognition.

The head of the New Flemish Alliance took office on 3 February 2025. A Flemish nationalist thereby reached the head of the federal government.

The Flemish Liberal took office after a caretaker government had run the country since October 2019. His appointment restored a full federal executive.

The party surged in the federal elections in the Dutch-speaking north. The result deepened the fragmentation of the political landscape and prolonged government formation difficulties.

A new calculation method including the area from the coast to the low-water line found the country 160 km2 larger than previously thought. Total surface was restated at 30,689 km2.

The attacks on 22 March 2016 struck the departure hall at Zaventem airport and a train at Maalbeek metro station, also killing three attackers and wounding several hundred people. The bombings were linked to the network behind the November 2015 Paris attacks.

After further N-VA gains in the 2014 federal election, King Philippe tasked Michel and Kris Peeters with forming a government of N-VA, CD&V, Open Vld and MR. Michel later became President of the European Council in July 2019.

The Belgian physicist and Peter Higgs had proposed the theory behind the particle in 1964; it was experimentally confirmed at CERN's Large Hadron Collider in 2012, a year before the prize was awarded.

After the June 2010 federal election, in which the Flemish nationalist N-VA became the largest party in Flanders and the PS in Wallonia, formation talks deadlocked under Leterme's caretaker cabinet. By March 2011 this set a world record, ended only when the Di Rupo government was sworn in in December 2011.

The reform placed Belgium at the forefront of civil rights legislation internationally. It followed the wider liberalising agenda of the purple coalition.

Belgium became one of the first states to permit euthanasia under law. Age restrictions were lifted in 2014, and a child with an incurable disease died through euthanasia in 2016.

Belgium switched to the euro in 2002, with the first euro coins minted in 1999. The franc, in use since 1832, was retired.

His governments achieved a balanced budget, tax and labour-market reforms, a scheduled nuclear phase-out and new war crimes and drug legislation. The coalition ended the long Christian Democrat dominance dating from 1958.

The armed forces became an all-volunteer body, later also open to citizens of other EU states, Iceland, Norway, Switzerland and Liechtenstein. By 2023 the military had 23,200 active personnel.

Scandals surrounding Marc Dutroux, Andre Cools, the dioxin food contamination crisis, the Agusta affair and the murder of Karel van Noppen shook public confidence. The first dioxin crisis broke a string of Christian Democrat coalition governments that had run since 1958.

The reform opened naturalisation more widely to migrants. More than 1.3 million migrants have since acquired Belgian citizenship, reshaping the country's demographic profile.

Macroeconomic policies left a cumulative debt burden of roughly 120% of GDP by the end of the decade. Sustained consolidation brought the budget into balance and debt to 90.3% of GDP by 2006.

The shocks hit hardest in Wallonia, where the steel industry lost competitiveness and declined seriously. The economic centre of gravity shifted north towards the Flemish Diamond during the 1980s and 1990s.

Political divisions between the Dutch-speaking Flemings of the north and the French-speaking Walloons of the south led to constitutional revisions in 1970, 1980, 1988 and 1993 that transformed Belgium from a unitary into a federal state, segregating political power into three levels of autonomous Communities and Regions. Belgium's national parties also split into separate Flemish and francophone components from around 1970.

For the first time the constitution existed authoritatively in Dutch as well as French. It marked the formal end of French legal primacy.

Legislation fixed Dutch, French, German and bilingual language areas. These boundaries became the basis for successive constitutional revisions creating the federal state.

Congolese independence was declared on 30 June 1960. Its first prime minister, Patrice Lumumba, was removed from power and killed in January 1961 in events in which Belgian officials were later found to have played a role.

Signed on 25 March 1957, the Treaty of Rome established the EEC alongside France, West Germany, Italy, Luxembourg and the Netherlands, and Belgium was also a founder of the European Atomic Energy Community (Euratom) the same year. The EEC evolved into the European Union, and Brussels went on to host the headquarters of the European Commission and, later, NATO.

The disaster on 8 August 1956 began when machinery was started before a coal wagon was properly loaded, rupturing cables and starting a fire that destroyed the shaft's winch mechanism. It remains the deadliest industrial accident in Belgian history and prompted changes to Italy-Belgium labour migration arrangements.

Belgium was one of the six founders of the ECSC. It went on to found the EEC and Euratom in 1957 and to host the European Commission, Council and parliamentary committee sessions.

Many Belgians believed he had collaborated with Germany during the war, and a general strike compelled his abdication in favour of his son Baudouin. The Royal Question tested the monarchy's survival.

The treaty was signed in Washington on 4 April 1949. Brussels later became home to NATO's political and military headquarters, cementing the country's role at the centre of Western European security cooperation.
