This work examines the cathedral chapter of St. Petri in Bautzen from its founding prior to 1221 through 1569. With the transfer of the apostolic administrature to the chapter of Bautzen, a new era began for this institution. After the Meissen chapter, Bautzen was the diocese’s most significant spiritual institution. The focus of the study is on the lives of the diocesan personnel and the internal constitution and economy of the diocese.
