Languages of Belgium
Dutch is the official language of the Flemish Community and the Flemish Region (merged to Flanders) and, along with French, an official language of the Brussels-Capital Region. The main Dutch dialects spoken in Belgium are Brabantian, West Flemish, East Flemish and Limburgish. All these are spoken across the border in the Netherlands as well, and West Flemish is also spoken in French Flanders. Much like English, Flemish dialects have adopted much more French and other Romance vocabulary through mutual cultural exchange throughout history when compared with other Dutch dialects and as such they are not always readily intelligible for Dutch speakers outside Flanders. Words which are unique to Belgian Dutch are called "belgicisms" (as are words used primarily in Belgian French). The original Brabantian dialect of Brussels has been very much influenced by French. It is now spoken by a minority in the Capital region since the language of most inhabitants shifted during the Frenchification of Brussels.
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.
