How did the Concordat of Worms affect the power of bishops in the Low Countries?

The Concordat of Worms (1122) significantly diminished the direct influence of the German imperial power over bishops in the Low Countries. Prior to this agreement, the Holy Roman emperors had systematically strengthened their authority by nominating and investing bishops with secular powers, effectively using them as pillars of government and reliable instruments of rule.12

Following the concordat, the right to choose bishops was transferred to the cathedral chapters of canons. While the king retained some influence over these elections, the shift in procedure meant that local counts were often able to exert the most significant pressure on the chapters. Consequently, bishoprics such as Utrecht began to see bishops appointed from the families of local counts, such as those of Holland and Guelders. This transition marked the end of the strong, direct control the German monarchy had previously exercised through the episcopal office, allowing local secular and spiritual princes to consolidate their own power within the region.1
