Belgium (/ˈbɛldʒəm/ bel-jəm), officially the Kingdom of Belgium, is a federal state in Western Europe. It is a founding member of the European Union and hosts the EU's headquarters, and those of several other major international organisations such as NATO. Belgium covers an area of 30,528 square kilometres (11,787 sq mi), and it has a population of about 11 million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups, the Dutch-speakers, mostly Flemish (about 60%), and the French-speakers, mostly Walloons (about 40%), plus a small group of German-speakers. Belgium's two largest regions are the Dutch-speaking region of Flanders in the north and the French-speaking southern region of Wallonia. The Brussels-Capital Region, officially bilingual, is a mostly French-speaking enclave within the Flemish Region. A German-speaking Community exists in eastern Wallonia. Belgium's linguistic diversity and related political conflicts are reflected in the political history and a complex system of government.

Historically, the present day states of Belgium, the Netherlands, Luxembourg together with the North of France (Artois, French Flanders), and a small part of Western Germany, were known as the Low Countries. These regions were unitied in a personal union of states starting the 14th and during the 15th and 16th century. The Low Countries were called Belgica in Latin after the Roman province Gallia Belgica which covered the core of the same area. From the end of the Middle Ages until the 17th century, it was a prosperous centre of commerce and culture. From the 16th century until the Belgian Revolution in 1830, when Belgium seceded from the Netherlands, many battles between European powers were fought in the area of Belgium, causing it to be dubbed the battleground of Europe, a reputation strengthened by both World Wars.

Upon its independence, Belgium participated in the Industrial Revolution and, during the course of the 20th century, possessed a number of colonies in Africa. The second half of the 20th century was marked by the rise of non-violent conflicts between the Flemish and the Francophones fuelled by cultural differences on the one hand and an asymmetrical economic evolution of Flanders and Wallonia on the other hand. These still-active conflicts have caused far-reaching reforms of the formerly unitary Belgian state into a federal state which may lead to a complete partition of the country in the future.

The name 'Belgium' is derived from Gallia Belgica, a Roman province in the northernmost part of Gaul that, before Roman invasion in 100 BC, was inhabited by the Belgae, a mix of Celtic and Germanic peoples. A gradual immigration by Germanic Frankish tribes during the 5th century brought the area under the rule of the Merovingian kings. A gradual shift of power during the 8th century led the kingdom of the Franks to evolve into the Carolingian Empire. The Treaty of Verdun in 843 divided the region into Middle and West Francia and therefore into a set of more or less independent fiefdoms which, during the Middle Ages, were vassals either of the King of France or of the Holy Roman Emperor.

Many of these fiefdoms were united in the Burgundian Netherlands of the 14th and 15th centuries. Emperor Charles V extended the personal union of the Seventeen Provinces in the 1540s, making it far more than a personal union by the Pragmatic Sanction of 1549 and increased his influence over the Prince-Bishopric of Liège. The Eighty Years' War (1568–1648) divided the Low Countries into the northern United Provinces (Belgica Foederata in Latin, the "Federated Netherlands") and the Southern Netherlands (Belgica Regia, the "Royal Netherlands"). The latter were ruled successively by the Spanish and the Austrian Habsburgs and comprised most of modern Belgium. This was the theatre of most Franco-Spanish and Franco-Austrian wars during the 17th and 18th centuries. Following the campaigns of 1794 in the French Revolutionary Wars, the Low Countries—including territories that were never nominally under Habsburg rule, such as the Prince-Bishopric of Liège—were annexed by the French First Republic, ending Austrian rule in the region. The reunification of the Low Countries as the United Kingdom of the Netherlands occurred at the dissolution of the First French Empire in 1815.

The 1830 Belgian Revolution led 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 21 July 1831 (which 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 century. French was originally the single official language adopted by the nobility and the bourgeoisie. It progressively lost its overall importance as Dutch became recognised as well. This recognition became official in 1898 and in 1967 a Dutch version of the Constitution was legally accepted.

The Berlin Conference of 1885 ceded control of the Congo Free State to King Leopold II as his private possession. From around 1900 there was growing international concern for the extreme and savage treatment of the Congolese population under Leopold II, for whom the Congo was primarily a source of revenue from ivory and rubber production. In 1908 this outcry led the Belgian state to assume responsibility for the government of the colony, henceforth called the Belgian Congo. Germany invaded Belgium in 1914 as part of the Schlieffen Plan and much of the Western Front fighting of World War I occurred in western parts of the country. The opening months of the war were known as the Rape of Belgium due to German atrocities. Belgium took over the German colonies of Ruanda-Urundi (modern day Rwanda and Burundi) during the war, and they were mandated to Belgium in 1924 by the League of Nations. In the aftermath of the First World War, the Prussian districts of Eupen and Malmedy were annexed by Belgium in 1925, thereby causing the presence of a German-speaking minority.

The country was again invaded by Germany in 1940 and was occupied until its liberation by the Allies in 1944. After World War II, a general strike forced king Leopold III, who many saw as collaborating with the Germans during the war, to abdicate in 1951. The Belgian Congo gained independence in 1960 during the Congo Crisis; Ruanda-Urundi followed with its independence two years later. Belgium joined NATO as a founding member and formed the Benelux group of nations with the Netherlands and Luxembourg. Belgium became one of the six founding members of the European Coal and Steel Community in 1951 and of the European Atomic Energy Community and European Economic Community, established in 1957. The latter is now the European Union, for which Belgium hosts major administrations and institutions, including the European Commission, the Council of the European Union and the extraordinary and committee sessions of the European Parliament.

Despite its political and linguistic divisions, the region corresponding to today's Belgium has seen the flourishing of major artistic movements that have had tremendous influence on European art and culture. Nowadays, to a certain extent, cultural life is concentrated within each language Community, and a variety of barriers have made a shared cultural sphere less pronounced. Since the 1970s, there are no bilingual universities in the country except the Royal Military Academy and the Antwerp Maritime Academy, no common media and no single large cultural or scientific organisation in which both main communities are represented. The forces that once held the Belgians together—Roman Catholicism and economic and political opposition to the Dutch—are no longer strong.

Fine arts

Contributions to painting and architecture have been especially rich. The Mosan art, the Early Netherlandish, the Flemish Renaissance and Baroque painting and major examples of Romanesque, Gothic, Renaissance and Baroque architecture are milestones in the history of art. While the 15th century's art in the Low Countries is dominated by the religious paintings of Jan van Eyck and Rogier van der Weyden, the 16th century is characterized by a broader panel of styles such as Peter Breughel's landscape paintings and Lambert Lombard's representation of the antique. Though the Baroque style of Peter Paul Rubens and Anthony van Dyck flourished in the early 17th century in the Southern Netherlands, it gradually declined thereafter.

During the 19th and 20th centuries many original romantic, expressionist and surrealist Belgian painters emerged, including James Ensor and other artists belonging to the Les XX group, Constant Permeke, Paul Delvaux and René Magritte. The avant-garde CoBrA movement appeared in the 1950s, while the sculptor Panamarenko remains a remarkable figure in contemporary art. The multidisciplinary artist Jan Fabre and the painter Luc Tuymans are other internationally renowned figures on the contemporary art scene. Belgian contributions to architecture also continued into the 19th and 20th centuries, including the work of Victor Horta and Henry van de Velde, who were major initiators of the Art Nouveau style.

The vocal music of the Franco-Flemish School developed in the southern part of the Low Countries and was an important contribution to Renaissance culture. In the 19th and 20th centuries, there was an emergence of major violinists, such as Henri Vieuxtemps, Eugène Ysaÿe and Arthur Grumiaux, while Adolphe Sax invented the saxophone in 1846. The composer César Franck was born in Liège in 1822. Contemporary music in Belgium is also of repute. Jazz musician Toots Thielemans and singer Jacques Brel have achieved global fame. In rock/pop music, Telex, Front 242, K's Choice, Hooverphonic, Zap Mama, Soulwax and dEUS are well known. In the heavy metal scene, bands like Machiavel, Channel Zero and Enthroned have a worldwide fan-base.

Belgium has produced several well-known authors, including the poet Emile Verhaeren and novelists Hendrik Conscience, Georges Simenon, Suzanne Lilar and Amélie Nothomb. The poet and playwright Maurice Maeterlinck won the Nobel Prize in literature in 1911. The Adventures of Tintin by Hergé is the best known of Franco-Belgian comics, but many other major authors, including Peyo (The Smurfs), André Franquin (Gaston Lagaffe), Edgar P. Jacobs and Willy Vandersteen brought the Belgian cartoon strip industry a worldwide fame.

Belgian cinema has brought a number of mainly Flemish novels to life on-screen. Other Belgian directors include André Delvaux, Stijn Coninx, Luc and Jean-Pierre Dardenne; well-known actors include Jan Decleir and Marie Gillain; and successful films include Man Bites Dog and The Alzheimer Affair. In the 1980s, Antwerp's Royal Academy of Fine Arts produced important fashion trendsetters, known as the Antwerp Six.

Folklore

Folklore plays a major role in Belgium's cultural life: the country has a comparatively high number of processions, cavalcades, parades, 'ommegangs' and 'ducasses', 'kermesse' and other local festivals, nearly always with an originally religious or mythological background. The Carnival of Binche with its famous Gilles and the 'Processional Giants and Dragons' of Ath, Brussels, Dendermonde, Mechelen and Mons are recognised by UNESCO as Masterpieces of the Oral and Intangible Heritage of Humanity.

Other examples are the Carnival of Aalst; the still very religious processions of the Holy Blood in Bruges, Virga Jesse Basilica in Hasselt and Basilica of Our Lady of Hanswijk in Mechelen; 15 August festival in Liège; and the Walloon festival in Namur. Originated in 1832 and revived in the 1960s, the Gentse Feesten have become a modern tradition. A major non-official holiday is the Saint Nicholas Day, a festivity for children and, in Liège, for students.

Cuisine

Many highly ranked Belgian restaurants can be found in the most influential restaurant guides, such as the Michelin Guide. Belgium is famous for beer, chocolate, waffles and french fries. Contrary to their name, french fries also originated in Belgium. The national dishes are "steak and fries with salad", and "mussels with fries".

Brands of Belgian chocolate and pralines, like Côte d'Or, Guylian, Neuhaus, Leonidas, Corné and Galler are famous, as well as independent producers such as Burie and Del Rey in Antwerp and Mary's in Brussels. Belgium produces over 500 varieties of beer. The Trappist beer of the Abbey of Westvleteren has repeatedly been rated the world's best beer. The biggest brewer in the world by volume is Anheuser-Busch InBev, based in Leuven.

Sports

Since the 1970s, sports clubs and federations are organised separately within each language community. Association football is one of the most popular sports in both parts of Belgium, together with cycling, tennis, swimming and judo. With five victories in the Tour de France and numerous other cycling records, Belgian Eddy Merckx is regarded as one of the greatest cyclists of all time. His hour speed record (set in 1972) stood for 12 years. Jean-Marie Pfaff, a former Belgian goalkeeper, is considered one of the greatest in the history of football. Belgium and The Netherlands previously hosted the UEFA European Football Championship in 2000. Belgium hosted the 1972 European Football Championships.

Kim Clijsters and Justine Henin both were Player of the Year in the Women's Tennis Association as they were ranked the number one female tennis player. The Spa-Francorchamps motor-racing circuit hosts the Formula One World Championship Belgian Grand Prix. The Belgian driver, Jacky Ickx, won eight Grands Prix and six 24 Hours of Le Mans and finished twice as runner-up in the Formula One World Championship. Belgium also has a strong reputation in motocross. Sporting events annually held in Belgium include the Memorial Van Damme athletics competition, the Belgian Grand Prix Formula One, and a number of classic cycle races such as the Tour of Flanders and Liège–Bastogne–Liège. The 1920 Summer Olympics were held in Antwerp.

Belgium shares borders with France (620 km), Germany (167 km), Luxembourg (148 km) and the Netherlands (450 km). Its total area, including surface water area, is 33,990 square kilometres; land area alone is 30,528 km. It lies between latitudes 49° and 53° N, and longitudes 2° and 7° E.

Belgium has three main geographical regions: the coastal plain in the north-west and the central plateau both belong to the Anglo-Belgian Basin; the Ardennes uplands in the south-east are part of the Hercynian orogenic belt. The Paris Basin reaches a small fourth area at Belgium's southernmost tip, Belgian Lorraine.

The coastal plain consists mainly of sand dunes and polders. Further inland lies a smooth, slowly rising landscape irrigated by numerous waterways, with fertile valleys and the northeastern sandy plain of the Campine (Kempen). The thickly forested hills and plateaus of the Ardennes are more rugged and rocky with caves and small gorges. Extending westward into France, this area is eastwardly connected to the Eifel in Germany by the High Fens plateau, on which the Signal de Botrange forms the country's highest point at 694 metres (2,277 ft).

The climate is maritime temperate with significant precipitation in all seasons (Köppen climate classification: Cfb), as is the case with all areas adjacent to the North Sea, including The Netherlands and much of the United Kingdom. The average temperature is lowest in January at 3 °C (37.4 °F) and highest in July at 18 °C (64.4 °F). The average precipitation per month varies between 54 millimetres (2.1 in) for February or April, to 78 mm (3.1 in) for July. Averages for the years 2000 to 2006 show daily temperature minimums of 7 °C (44.6 °F) and maximums of 14 °C (57.2 °F) and monthly rainfall of 74 mm (2.9 in); these are about 1 °C and nearly 10 millimetres above last century's normal values, respectively.

Phytogeographically, Belgium is shared between the Atlantic European and Central European provinces of the Circumboreal Region within the Boreal Kingdom. According to the World Wide Fund for Nature, the territory of Belgium belongs to the ecoregion of Atlantic mixed forests. Because of its high population density, its location in the centre of Western Europe and inadequate political effort, Belgium faces serious environmental problems. A 2003 report suggested Belgian natural waters (rivers and groundwater) to have the lowest water quality of the 122 countries studied. In the 2006 pilot Environmental Performance Index, Belgium scored 75.9% for overall environmental performance and was ranked lowest of the EU member countries, though it was only 39th of 133 countries.
