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.
Brussels and the European Union
Belgium operates a complex federal system between the two main groups: Flemish and Walloons. There's a division of Belgium into three regions, where Brussels-Capital Region is an independent region, next to Flanders and Wallonia. The regions are mostly responsible for the economy, mobility and other territory-related matters. But there's also a division of Belgium into three communities: the Flemish Community, the French Community and the German-speaking Community. These communities are responsible for language-related matters like culture or education. Brussels doesn't belong to any community, but has a bilingual status. So the Brussels inhabitants may enjoy education or cultural affairs or education organised by the Flemish and/or the French community.
