 In 925, Cambrai came into the possession of East Francia (later the Holy Roman Empire) and, together with the surrounding area, constituted a county, which would become known as "Cambrésis", the genitive of "Cambrai".The last dynastic count, Arnold of Valenciennes, renounced his comital rights to Cambrésis to obtain the support of the bishop of Cambrai against his enemy Baldwin IV, Count of Flanders.The German king Henry II transferred the comital rights to the bishop of Cambrai in 1007, in line with the Ottonian policy of creating an Imperial Church System.
