Provinces of Belgium
Most of the provinces take their name from earlier duchies and counties of similar location, while their territory is mostly based on the departments installed during French annexation. At the time of the creation of Belgium in 1830, only nine provinces existed, including the province of Brabant, which held the city of Brussels. In 1995, Brabant was split into three areas: Flemish Brabant, which became a part of the region of Flanders; Walloon Brabant, which became part of the region of Wallonia; and the Brussels-Capital Region, which became a third region. These divisions reflected political tensions between the French-speaking Walloons and the Dutch-speaking Flemish; the Brussels-Capital Region is officially bilingual.
Chamber of Representatives (Belgium)
Article 62 of the Belgian Constitution fixes the number of seats in the Chamber of Representatives at 150. There are 11 electoral districts, which correspond with the ten Provinces (five Dutch- and five French-speaking) and the Brussels-Capital Region. Prior to the sixth Belgian state reform, the province of Flemish Brabant was divided into two electoral districts: one for Leuven and the other, named Brussels-Halle-Vilvoorde (BHV), which encompassed both the 19 bilingual municipalities from the Brussels-Capital Region and the 35 Dutch-speaking municipalities of Halle-Vilvoorde in Flemish Brabant, including seven municipalities with linguistic facilities for French-speaking inhabitants.
