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.
Belgian Provincial Leagues
The Belgian Provincial leagues are the lower leagues for Belgian football. Until 2016, these were at levels 5-8 in the Belgian football league system however as part of the reform an extra level was created causing the provincial leagues to drop to levels 6-9. The provincial leagues are divided into 9 regional league systems (one for each province, but Flemish Brabant and Walloon Brabant are merged and contain also the football teams from the Brussels Capital Region). Each league system is itself divided into 4 levels (except for Luxembourg where there are only 3). The number of leagues at each level depends on the province, but every province must have only one league at the top level. The best teams from the 9 first divisions can promote to the Belgian Third Amateur Division, the fifth and lowest level in the national leagues (either directly, or after playoff matches).
