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
The majority of those in the north of the country spoke Dutch and other Low Franconian languages while those in the south spoke Langues d'oïl such as French, Walloon and Picard. French became the official language of government after the separation from the Netherlands in 1830 and Belgian cultural life was especially dominated by the French influence, reinforced by economic domination of the industrial south. Flemish was "reduced to the tongue of a second-class culture." Parts of the Flemish population reacted against this, agitating for the equality of their language with French. This was partly due to a sense of growing Flemish identity, made possible through greater awareness of Flemish culture and history from the 1840s. Flemish victories, like the Battle of the Golden Spurs in 1302 were celebrated and a Flemish cultural movement, led by figures like Hendrik Conscience was born. About the same time a Walloon Movement emerged, led by Jules Destrée (1863–1936) and based on loyalty to the French language. Universal suffrage meant the Francophones were a political minority, so the Walloon Movement concentrated on protecting French where it had a majority, and did not contest the expanded use of Dutch in Flemish areas.
