Diocesan feud
A diocesan feud (German: Stiftsfehde) is either a warlike conflict between two contenders for the election of a prince-bishop, ruler of a bishopric or archbishopric in the Holy Roman Empire, or an armed conflict between two parties within such a territory. The introduction of the Imperial Church System in the 10th century had intended the position of prince-bishops to be non-hereditary, as all Catholic clergymen were required to be celibate and thus could not produce legitimate offspring to inherit their possessions.
