The Prince-Bishopric of Osnabrück was a prince-bishopric centered on the Roman Catholic Diocese of Osnabrück. The diocese was erected in 772 and is the oldest see founded by Charlemagne, in order to Christianize the conquered stem-duchy of Saxony. The temporal possessions of the see, originally quite limited, grew in time, and its prince-bishops exercised an extensive civil jurisdiction within the territory covered by their rights of immunity. The Prince-Bishopric continued to grow in size, making its status during the Reformation a highly contentious issue.
