Belgium became independent from the Netherlands in 1830 after lengthy periods under Roman, Frankish, Burgundian, Spanish, and Austrian rule. The country was occupied by Germany during both World Wars I and II. Modern Belgium is a technologically-advanced European state and member of NATO and the EU, though tensions between Dutch-speaking Flemish of the north and French-speaking Walloons of the south have led to constitutional amendments granting these regions formal recognition and autonomy.

Belgium's history involves centuries of foreign rule, occupation, and cultural division. Understanding this complex past helps explain the country's unique federal structure and ongoing linguistic tensions. From Roman conquest to modern European integration, Belgium has continuously evolved as a crossroads of European culture and power.

Early History: Before Belgium Existed

The territory now known as Belgium has no obvious historical start or finish as a unified entity. The first inhabitants, the Omalians, settled the region during the Neolithic period. The Michelsbergs brought warrior culture, followed by the Metal and Bronze Age civilizations that introduced daily tools and weapons.

In the Second Century BCE, Celtic tribes arrived, bringing their language and culture. The region became known for its fierce Celtic warriors and pastoral communities. This Celtic period established cultural patterns that would influence the region for centuries.

Roman Conquest and Civilization (56 BCE - 455 CE)

In 56 BCE, Julius Caesar conquered the region during his Gallic Wars. The Romans called the inhabitants "Belgae" and noted their fierce resistance. Roman rule brought roads, cities, trade networks, and Latin language. Major Roman settlements included present-day Tongeren, the oldest town in Belgium.

Roman influence introduced urban planning, public baths, forums, and Christianity. The Pax Romana brought centuries of relative peace and prosperity. Latin replaced Celtic languages among educated classes, though rural areas maintained traditional languages and customs.

Frankish Empire and the Great Divide (455-843)

As Rome collapsed, Frankish tribes moved into the region. The Merovingian Dynasty established Frankish rule, but the most significant ruler was Charlemagne (750-843). His empire united much of Western Europe, and he was crowned Holy Roman Emperor in 800 CE.

The Treaty of Verdun (843) divided Charlemagne's empire among his grandsons, creating the linguistic divide that still defines Belgium. The northern regions fell under Germanic influence while the south remained Romance-language speaking. This division created the Flemish-Walloon split that continues today.

Medieval Period: Trade, Prosperity, and Feudalism

The Middle Ages brought plague, famine, and insurrection, but also remarkable prosperity. Flemish cities like Bruges, Ghent, and Ypres became major trading centers. The cloth trade made Belgium one of Europe's wealthiest regions. Gothic architecture flourished, with magnificent cathedrals and city halls constructed.

The Crusades began partly due to Belgian religious fervor. Godfrey of Bouillon, Duke of Lower Lorraine, led the First Crusade and became the first ruler of Jerusalem. Belgian merchants profited enormously from Crusader trade routes.

Burgundian Era: The Golden Age

The Dukes of Burgundy ruled the Low Countries from 1384 to 1477, creating a unified territory. This era brought unprecedented wealth, artistic achievement, and political stability. Jan van Eyck and other Flemish Primitive painters revolutionized European art. Burgundian court culture influenced all of Europe.

Habsburg Rule and Spanish Netherlands (1477-1715)

Through marriage, the region passed to the Habsburg dynasty. Charles V, born in Ghent, ruled a vast empire including Spain, the Low Countries, and much of the Americas. His son Philip II inherited the Spanish Netherlands but faced the Dutch Revolt (1568-1648).

The northern provinces (modern Netherlands) successfully rebelled and gained independence. The southern provinces (modern Belgium) remained under Spanish control. This period saw religious persecution, economic decline, and repeated warfare. The Spanish Inquisition burned suspected heretics throughout the region.

Austrian Rule and Enlightenment (1715-1792)

The Spanish Netherlands passed to Austrian Habsburg control after the War of Spanish Succession. Austrian rule brought Enlightenment reforms, improved administration, and relative peace. However, attempts to centralize power sparked the Brabant Revolution (1789-1790), creating the short-lived United States of Belgium, Europe's first attempt at a federal republic after American independence.

French Rule and Congress of Vienna (1792-1815)

Revolutionary France conquered Belgium in 1792, incorporating it directly into France. The Napoleonic period brought legal reforms (the Napoleonic Code), secularization, and conscription. After Napoleon's defeat, the Congress of Vienna (1815) united Belgium with the Netherlands under King William I.

Belgian Independence (1830)

The union with the Netherlands proved unpopular. Cultural, linguistic, and religious differences created constant tension. In August 1830, inspired by the July Revolution in Paris, Brussels rose in revolt. By October, Belgian independence was declared. The major European powers recognized Belgium as an independent, neutral kingdom in 1831, with Leopold I as its first king.

Modern Belgium: World Wars and European Integration

Despite guaranteed neutrality, Germany invaded Belgium in both World Wars. World War I devastated the country, with most fighting occurring on Belgian soil. Ypres, Passchendaele, and other battles killed hundreds of thousands. World War II brought renewed occupation and the Holocaust.

Post-war Belgium embraced European integration. Brussels became the de facto capital of the European Union, hosting EU institutions and NATO headquarters. Belgium transformed into a federal state with separate Flemish, Walloon, and Brussels regions, each with significant autonomy. Linguistic tensions continue, but Belgium remains stable and prosperous.
