Rape of Belgium in the context of Évariste Carpentier

For most of its history, what is today Belgium was either a part of a larger territory, such as the medieval Carolingian Empire, or was divided into a number of smaller states. In the Middle Ages, the territory of present-day Belgium was fragmented into numerous feudal principalities, including the Duchy of Lower Lorraine, the Duchy of Brabant, the County of Flanders, the Prince-Bishopric of Liège, the County of Namur, the County of Hainaut and the County of Luxembourg. Belgium's modern shape can be traced back at least as far as the southern core of the medieval Burgundian Netherlands. The Eighty Years' War (1568–1648) later led to the split between a northern Dutch Republic and the Southern Netherlands from which Belgium and Luxembourg developed. The area, long a Habsburg stronghold, briefly came under Bourbon control during the War of the Spanish Succession. The resulting Peace of Utrecht transferred the area back to Habsburg control, creating what is now known as the Austrian Netherlands. The French Revolutionary wars led to Belgium becoming part of France in 1795. After the defeat of the French in 1814, the Congress of Vienna created two new states, the United Kingdom of the Netherlands and the Grand Duchy of Luxembourg, which were placed in dynastic union under the House of Orange-Nassau. The Southern Netherlands rebelled during the 1830 Belgian Revolution, establishing the modern Belgian state, officially recognized at the London Conference of 1830. The first King of Belgium, Leopold I, assumed the throne in 1831.

The first half of the twentieth century was tumultuous. Its historic neutrality was violated in each of the World Wars. During World War I, frustrated German invaders launched the Rape of Belgium. During the 1940 invasion, the quick surrender by Leopold III of Belgium to German forces drove a wedge between the King and his people. The King's attempt to return led to a constitutional crisis in 1950, which led to his abdication in favor of his son Baudouin. Belgium entered the second half of the twentieth century showing an unprecedented era of economic growth, as Belgium took an active role in the formation of the Benelux customs union with its neighbors. Ultimately, the Benelux union would serve as a model for the European Economic Community, a precursor to the European Union; to this day Brussels serves as the seat of many of the European Union institutions.
