Belgium, officially the Kingdom of Belgium, is a country in Northwestern Europe. Situated in a coastal lowland region known as the Low Countries, it is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the south, and the North Sea to the west. Belgium covers an area of and has a population of more than 11.8 million; its population density of ranks 22nd in the world and sixth in Europe. The capital and largest metropolitan region is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven.

Belgium is a parliamentary constitutional monarchy with a complex federal system structured on regional and linguistic grounds. The country is divided into three highly autonomous regions: the Flemish Region (Flanders) in the north, the Walloon Region (Wallonia) in the south, and the Brussels-Capital Region in the middle. Belgium is also home to two main linguistic communities: the Dutch-speaking Flemish Community, which constitutes about 60 percent of the population, and the French-speaking French Community, which constitutes about 40 percent of the population; a small German-speaking Community, comprising around one percent of the population, exists in the East Cantons. Belgium's linguistic diversity and related political conflicts are reflected in its complex system of governance, made up of six different governments. Belgium is a developed country with an advanced high-income economy. It is one of the six founding members of the European Union, with its capital of Brussels serving as the de facto capital of the EU, hosting the official seats of the European Commission, the Council of the European Union, the European Council, and one of two seats of the European Parliament (the other being Strasbourg). Brussels also hosts the headquarters of many major international organisations, such as NATO.

In antiquity, present-day Belgium was dominated by the Belgae before being annexed into the Roman Empire in the mid first century BC. During the Middle Ages, Belgium's central location kept it relatively prosperous and connected both commercially and politically to its larger neighbours; it was part of the Carolingian Empire, the succeeding Holy Roman Empire, and subsequently the Burgundian Netherlands. Following rule by Habsburg Spain (1556–1714), the Austrian Habsburgs (1714–1794), and Revolutionary France (1794–1815), most of modern-day Belgium was incorporated into the United Kingdom of the Netherlands after the Congress of Vienna in 1815. Centuries of being contested and controlled by various European powers earned Belgium the moniker "the Battlefield of Europe",—The book reviewer, Haß, attributes the expression in English to James Howell in 1640. Howell's original phrase "the cockpit of Christendom" became modified afterwards, as shown by:*—and as such coined for Belgium:* (See also The Nuttall Encyclopaedia) a reputation reinforced in the 20th century by both world wars.

An independent Belgium was established in 1830 following the Belgian Revolution. In the 19th century it was one of the earliest participants in the Industrial Revolution, and the first country in continental Europe to become industrialised. By the early 20th century, it possessed several colonies, notably the Belgian Congo and Ruanda-Urundi, which gained independence between 1960 and 1962. The second half of the 20th century was marked by rising tensions between the Dutch-speakers and French-speakers, fueled by differences in political culture and the unequal economic development of Flanders and Wallonia. This has resulted in several far-reaching state reforms, including the transition from a unitary to federal structure between 1970 and 1993. Tensions persist amid ongoing reforms; the country faces a strong separatist sentiment among the Flemish, controversial language laws, and a fragmented political landscape that resulted in a record 589 days without a government formation following the 2010 federal election.

History

Antiquity

In his account of the Roman invasion of Gaul, Roman leader Julius Caesar noted that the original Belgae inhabited the northern part of Gaul extending from the Seine and Marne rivers to the Rhine. They therefore inhabited most of modern Belgium, and significant parts of France, the Netherlands, and Germany. He described the Belgae as the bravest of the Gauls, and attributed this to their distance from the Roman Province, minimal contact with merchants importing luxury goods, and their continual warfare with the neighbouring Germanic tribes across the Rhine. Within this broad region, Caesar referred to a specific area as "Belgium," which was politically dominant and located in what is now northern France.Caesar, Gallic War, 8.46 "quattuor legiones in Belgio collocavit", "his confectis rebus ad legiones in Belgium se recipit hibernatque Nemetocennae". (In online English translations the second part is often included in the next paragraph 8.47 . .

Modern Belgium, along with neighbouring regions of the Netherlands and Germany, corresponds to the territories of the northernmost Belgae tribes, including the Menapii, Nervii, the Atuatuci, and the Germani Cisrhenani. Julius Caesar described these tribes as particularly warlike and economically undeveloped, noting their kinship with the Germanic tribes east of the Rhine. Additionally, the area around Arlon in southern Belgium was part of the territory of the Treveri tribe, whose lands extended into present-day Luxembourg and adjacent regions of France and Germany.

Following Caesar's conquests, Gallia Belgica became the Latin name for a large Roman province encompassing most of Northern Gaul, including the lands of the Belgae and Treveri. Subsequently, Roman Belgica was divided into two parts, and the regions closer to the lower Rhine frontier, such as the eastern part of modern Belgium, were incorporated into the frontier province of Germania Inferior. As the central government of the Western Roman Empire collapsed, the provinces of Belgica and Germania were inhabited by a mix of Romanised populations and Germanic-speaking Franks, who came to dominate the military and political spheres.

Middle Ages During the 5th century, the area came under the rule of the Frankish Merovingian kings, who initially established a kingdom ruling over the Romanised population in what is now northern France, and then conquered the other Frankish kingdoms. During the 8th century, the empire of the Franks came to be ruled by the Carolingian dynasty, whose centre of power included the area which is now eastern Belgium. Over the centuries, it was divided up in many ways, but the Treaty of Verdun in 843 divided the Carolingian Empire into three kingdoms whose borders had a lasting impact on medieval political boundaries. Most of modern Belgium was in the Middle Kingdom, later known as Lotharingia, but the coastal county of Flanders, west of the Scheldt, became the northernmost part of West Francia, the predecessor of France. In 870 in the Treaty of Meerssen, modern Belgium lands all became part of the western kingdom for a period, but in 880 in the Treaty of Ribemont, Lotharingia came under the lasting control of the eastern kingdom, which eventually became the Holy Roman Empire. The lordships and bishoprics along the "March" (frontier) between the two great kingdoms maintained important connections between each other. For example, the county of Flanders expanded over the Scheldt into the empire, and during several periods was ruled by the same lords as the county of Hainaut.

In the 13th and 14th centuries, the cloth industry and commerce boomed especially in the County of Flanders and it became one of the richest areas in Europe. This prosperity played a role in conflicts between Flanders and the king of France. Famously, Flemish militias scored a surprise victory at the Battle of the Golden Spurs against a strong force of mounted knights in 1302, but France soon regained control of the rebellious province.

Burgundian and Habsburg Netherlands

In the 15th century, the French Duchy of Burgundy took control of Flanders, and from there proceeded to unite much of present-day Benelux, the so-called Burgundian Netherlands. "Burgundy" and "Flanders" were the first two common names used for the Burgundian Netherlands which was the predecessor of the Austrian Netherlands, the predecessor of modern Belgium. The union, technically stretching between two kingdoms, gave the area economic and political stability which led to an even greater prosperity and artistic creation.

Born in Belgium, the Habsburg Emperor Charles V was heir of the Burgundians, but also of the royal families of Austria, Castile and Aragon. With the Pragmatic Sanction of 1549 he gave the Seventeen Provinces more legitimacy as a stable entity, rather than just a temporary personal union. He also increased the influence of these Netherlands over the Prince-Bishopric of Liège, which continued to exist as a large semi-independent enclave.

Spanish and Austrian Netherlands The Eighty Years' War (1568–1648) was triggered by the Spanish government's policy towards Protestantism, which was becoming popular in the Low Countries. The rebellious northern United Provinces (Belgica Foederata in Latin, the "Federated Netherlands") eventually separated from the Southern Netherlands (Belgica Regia, the "Royal Netherlands"). The southern part continued to be ruled successively by the Spanish (Spanish Netherlands) and the Austrian House of Habsburgs (Austrian Netherlands) and comprised most of modern Belgium. This was the theatre of several more protracted conflicts during much of the 17th and 18th centuries involving France, including the War of Devolution (1667–1668), the Franco-Dutch War (1672–1678), the War of the League of Augsburg (1688–1697), the War of the Spanish Succession (1701–1714), and part of the War of the Austrian Succession (1740–1748).

French Revolution and United Kingdom of the Netherlands Following the campaigns of 1794 in the French Revolutionary Wars, the Low Countriesincluding territories that were never nominally under Habsburg rule, such as the Prince-Bishopric of Liègewere annexed by the French First Republic, ending Austrian rule in the region. After the dissolution of the First French Empire and the abdication of Napoleon following his defeat on the battlefield of Waterloo, the Congress of Vienna in 1814–15 created the United Kingdom of the Netherlands. This buffer state, located between the major European powers, united the former territories of the Dutch Republic, the Austrian Netherlands and the Prince-Bishopric of Liège, under King William I of Orange.

Independent Belgium

In 1830, the Belgian Revolution led to the re-separation of the Southern Provinces from the Netherlands and to the establishment of a Catholic and bourgeois, officially French-speaking and neutral, independent Belgium under a provisional government and a national congress. Since the installation of Leopold I as king on 1831, now celebrated as Belgium's National Day, Belgium has been a constitutional monarchy and parliamentary democracy, with a laicist constitution based on the Napoleonic Code. Although the franchise was initially restricted, universal suffrage for men was introduced after the general strike of 1893 (with plural voting until 1919) and for women in 1949.

The main political parties of the 19th century were the Catholic Party and the Liberal Party, with the Belgian Labour Party emerging towards the end of the 19th century. French was originally the official language used by the nobility and the bourgeoisie, particularly after the rejection of the Dutch monarchy. French progressively lost its dominance as Dutch began to recover its status. This recognition became official in 1898, and in 1967, the parliament accepted a Dutch version of the Constitution.
