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
Until the establishment of the Consulate in 1799, Catholics were heavily repressed by the French. The first University of Leuven was closed in 1797 and churches were plundered. During this early period of the French rule, the Belgian economy was completely paralyzed as taxes had to be paid in gold and silver coin while goods bought by the French were paid for with worthless assignats. During this period of systematic exploitation, about 800,000 Belgians fled the Southern Netherlands. The French occupation in Belgium led to further suppression of the Dutch language across the country, including its abolition as an administrative language. With the motto "one nation, one language", French became the only accepted language in public life as well as in economic, political, and social affairs.
