Provinces of Belgium
The country of Belgium is divided into three regions. Two of these regions, the Flemish Region or Flanders, and Walloon Region, or Wallonia, are each subdivided into five provinces. The third region, the Brussels-Capital Region, is not divided into provinces, as it was originally only a small part of a province itself.
History of Flanders
The contemporary territory of Flanders (i.e., the Flemish Region as the Dutch-speaking part of the Kingdom of Belgium) contains within it the core of the old county, West Flanders and East Flanders, plus three more provinces to the east which were not originally part of Flanders. These are the provinces of Antwerp and Flemish Brabant which were historically part of the Duchy of Brabant, and the province of Belgian Limburg, which was part of the Prince-Bishopric of Liège. (The city of Brussels, historically part of Brabant, is now politically part of the Flemish Community but not of the Flemish Region.)
