Provinces of Belgium
During the second half of the 20th century, Belgium transitioned from a unitary state to a federal state with three Communities and three Regions. As part of the state reforms, the (bilingual) province of Brabant was split in 1995 three ways: into two (unilingual) provinces (Flemish Brabant and Walloon Brabant) and into the (bilingual) Brussels-Capital Region. (The Brussels-Capital Region does not belong to any province, is not a province, and does not contain any provinces.) The two new Brabant provinces became part of the Flemish Region and the Walloon Region respectively. The remaining eight provinces became part of these regions as well, so the Flemish Region and the Walloon Region each contain five provinces.
History of Belgium
The successive linguistic disputes have made the successive Belgian governments very unstable. The three major parties (Liberal -right wing-, Catholic -center- and, Socialist -left wing-) all split in two according to their French- or Dutch-speaking electorate. A language border was determined by the first Gilson Act of November 8, 1962. The boundaries of certain provinces, arrondissements and municipalities were modified (among others, Mouscron became a part of Hainaut and Voeren became a part of Limburg) and facilities for linguistic minorities were introduced in 25 municipalities. On August 2, 1963, the second Gilson Act entered into force, fixing the division of Belgium into four language areas: a Dutch, a French and a German language area, with Brussels as a bilingual area.
