Languages of Belgium
Before the federal structure and the language legislation gradually introduced in the 20th century, French was generally the only language used by public authorities. For example, the Dutch version of the Constitution has enjoyed equal status to the original French one only since 1967, and the German version only since 1991.
Of the inhabitants of Belgium, roughly 59% belong to the Flemish Community, 40% to the French Community and 1% to the German-speaking Community, though these figures relating to official Belgian languages include unknown numbers of immigrants and their children speaking a foreign language as primary language, and of Belgian regional migrants which may be assumed to largely balance one another for natively French and Dutch speakers. Though the standard form of Dutch used in Belgium is almost identical to that spoken in the Netherlands and the different dialects spread across the border, it is often colloquially called "Flemish".
History of Belgium
Politically the country was once polarized on matters of religion and, in recent decades, it has faced new divisions over differences of language and unequal economic development. This ongoing antagonism has caused far-reaching reforms since the 1970s, changing the formerly unitary Belgian state into a federal state, and repeated governmental crises. It is now divided into three regions: Flanders (Dutch-speaking) in the north, Wallonia (French-speaking) in the south, and bilingual Brussels in the middle. There is also a German-speaking population along the border with Germany that was granted to Prussia in the Congress of Vienna in 1815 but added to Belgium following the 1919 Treaty of Versailles following World War I. German is the third official language of Belgium.
