Archbishopric of Hamburg-Bremen

The Archbishopric of Hamburg-Bremen was a prominent ecclesiastical territory in medieval northern Germany, established in the 9th century. It combined the spiritual authority of the archbishop with secular influence over the region, serving as a major religious and political center. The archbishopric played a key role in Christianizing the area and maintaining church administration, while also engaging in political diplomacy and territorial governance. Its importance grew during the Middle Ages, shaping regional history and church politics, until secular and ecclesiastical powers gradually shifted, affecting its influence in later centuries.
