County of Hainaut
The province derives from the French Revolutionary Jemmape department, formed in 1795 from part of the medieval County of Hainaut, the small territory of Tournai and the Tournaisis, a part of the county of Namur (Charleroi), and also a small part of the Prince-Bishopric of Liège (Thuin). (A large part of the historical county of Hainaut is now within France and sometimes referred to as French Hainaut.)
