List of bishops, prince-bishops, and administrators of Minden

This list records the bishops of the Roman Catholic Diocese of Minden (German: Bistum Minden), a suffragan of the Archdiocese of Cologne, who were simultaneously rulers of princely rank (prince-bishop) in the Prince-Bishopric of Minden (German: Hochstift Minden; est. 1180 and secularised in 1648), a state of imperial immediacy within the Holy Roman Empire. Minden was the seat of the chapter, the cathedral and residence of the bishops until 1305, Petershagen became the prince-episcopal residence since.

Titles of the incumbents of the Minden See

In 1180 part of the Minden diocesan territory were disentangled from the Duchy of Saxony and became an own territory of imperial immediacy called Prince-Bishopric of Minden, a vassal of the Holy Roman Empire. The prince-bishopric was an elective monarchy, with the monarch being the respective bishop usually elected by the Minden Cathedral chapter, and confirmed by the Holy See, or exceptionally only appointed by the Holy See. Papally confirmed bishops were then invested by the emperor with the princely regalia, thus the title prince-bishop. However, sometimes the respective incumbent of the see never gained a papal confirmation, but was still invested the princely regalia. Also the opposite occurred with a papally confirmed bishop, never invested as prince. A number of incumbents, elected by the chapter, neither achieved papal confirmation nor imperial investiture, but as a matter of fact nevertheless de facto held the princely power. Between about 1555 to 1631 all incumbents were Lutherans. The respective incumbents of the see bore the following titles:

• Bishop of Minden until 1180
• Prince-Bishop of Minden from 1180 to 1554 and again 1631 to 1648
• Administrator of the Prince-Bishopric of Minden 1566 to 1630 and again 1631 to 1645. Either simply de facto replacing the Prince-Bishop or lacking canon-law prerequisites the incumbent of the see would officially only hold the title administrator (but nevertheless colloquially referred to as Prince-Bishop).
