 In 870 this area was specifically described in the Treaty of Meerssen, when the Condroz was allocated for some decades to the kingdom of the western Franks (from which France evolved).As a church jurisdiction under Liège, already in about 800 the "Pagus Condrustinsus" was mentioned as one of only four divisions of the bishopric, along with Lomme, the Ardennes, and the Hesbaye.By 1497 the medieval jurisdictions, which were reformed in 1559, an archdeaconry of the Fammene had been created from the southern part (together with the Chimay deanery from the Lomme "pagus" west of the Meuse).
