Note: Not all incumbents of the Bremian See were imperially invested princely power as Prince-Archbishops and not all were papally confirmed as bishops. The respective incumbents of Bremen's see bore the following titles:

• Bishop of Bremen from 787 to 845
• Archbishop of Hamburg and Bishop of Bremen in personal union (colloquially also Archbishop of Hamburg-Bremen) from 848 to 1072
• Archbishop of Bremen (colloquially also Archbishop of Hamburg-Bremen) from 1072 to 1179
• Prince-Archbishop of Bremen from 1180 to 1566
• Administrator of the Prince-Archbishopric of Bremen from 1568 to 1645. Lacking canon-law prerequisites the incumbent of the See would officially only hold the title administrator (but nevertheless colloquially referred to as Prince-Archbishop). All administrators were Lutherans, except of one, Leopold Wilhelm, Archduke of Austria, who was Catholic.
• The last, but only provisional incumbent of the See, Franz Wilhelm von Wartenberg, therefore bore the title Vicar Apostolic (1645-1648)
