List of bishops of Schleswig

Between 1854 and 1864 the Lutheran church in the Duchy of Schleswig was reorganised as the Slesvig Stift [da] led again by a cleric titled bishop.

By the separation of state and religion after 1918 the privilege of the Prussian monarch as summus episcopus [de] (i.e. supreme governor/bishop of the church) was abolished.

After 1920 Northern Schleswig became part of the Vicariate Apostolic of Denmark, which transformed into the Roman Catholic Diocese of Copenhagen on 29 April 1953.

In Southern Schleswig the rest of the Prefecture Apostolic of Schleswig-Holstein was assigned to the Diocese of Osnabrück in 1929, which had to cede this extension again in favour of the new founded Archdiocese of Hamburg in 1994.

The Danish king as liege lord of the dukes of Schleswig deposed them in 1713 (confirmed in 1720), thereafter ducal co-rule was restricted to the Duchy of Holstein.
