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.
Provinces of the Netherlands
On 1 January 1796, under the Batavian Republic, Drenthe and Staats-Brabant became the eighth and ninth provinces of the Netherlands. The latter, which had been known as Bataafs Brabant (English: Batavian Brabant), changed its name to Noord Brabant, North Brabant, in 1815 when it became part of the United Kingdom of the Netherlands, which also contained (then) South Brabant, a province now in Belgium. This new unified state featured the provinces in their modern form, as non-autonomous subdivisions of the national state, and again numbering 17, though they were not all the same as the 16th century ones. In 1839, following the separation of Belgium, the province of Limburg was divided between the two countries, each now having a province called Limburg. A year later, Holland, the largest and most populous of the Dutch provinces, was also split into two provinces, for a total of 11. The 12th province to be created was Flevoland, consisting almost entirely of reclaimed land, established on 1 January 1986.
