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.
Municipalities of Belgium
Belgium comprises 581 municipalities (; ; ) grouped into five provinces in each of two regions and into a third region, the Brussels-Capital Region, comprising 19 municipalities that do not belong to a province. In most cases, the municipalities are the smallest administrative subdivisions of Belgium, but in municipalities with more than 100,000 inhabitants, on the initiative of the local council, sub-municipal administrative entities with elected councils may be created. As such, only Antwerp, having over 500,000 inhabitants, became subdivided into nine districts (). The Belgian arrondissements (also in French as well as in Dutch), an administrative level between province (or the capital region) and municipality, or the lowest judicial level, are in English sometimes called districts as well.
