A small principality around the cathedral town of Verden on the Aller and the castle of Rotenburg on the Wümme, which Bishop Rudolf built in 1195 against the archbishop of Bremen.
The bishop's own lands are a small part of his diocese, which reaches east over the Welf heartland round Lüneburg. Rudolf is named among Philip's princes in the Speyer declaration of 28 May 1199, but his little territory lies between the Welf lands and Bremen, and his loyalty cannot be very firm.

en.wikipedia Prince-Bishopric of Verden; Speyer declaration of 28 May 1199
Overlord
the king; he backs Philip of Swabia on paper
What the realm holds
- the cathedral town of Verden on the Aller
- the castle of Rotenburg on the Wümme (built 1195)
- the see's lands in the old Sturmigau between the Aller and the Wümme
How it was acquired
The see's temporal lordship took shape after the break-up of Saxony in 1180 (en.wikipedia).
Allies and rivals
Allies: the Staufen party, as far as the Speyer list shows. Rivals: the archbishop of Bremen (Rotenburg), the Welf brothers in Lüneburg, who surround the diocese.
The realm that morning
Rudolf holds Verden and Rotenburg. He backs Philip on paper (Speyer, May 1199). Nothing places him in the field in 1199.
Wealth
Market and toll at Verden on the Aller crossing, the see's estates, tithes from a large diocese.
Military
Rotenburg castle and the walls of the cathedral precinct at Verden; the see's ministeriales.
Threats
- the Welf brothers, whose lands enclose the diocese
- the archbishop of Bremen
Consort
none (a churchman)
Heirs
none: the chapter elects. His successor in 1205 will be Iso of Wölpe, brother of Count Bernhard II of Wölpe.
Officers
Advocate (Vogt), chapter dignitaries and ministeriales on 1 January 1200: not pinned.
Court in 1200
Verden or Rotenburg (not pinned).
Treaties
None known for 1199-1200.
Feuds
Rivalry with the archbishop of Bremen, the reason for Rotenburg (1195).
Throne war
Philip (Staufen), at least since 28 May 1199, when he is named in the Speyer declaration. Firmness: weak to fair; his neighbours to the east are the Welfs.
Relations with rome
Nothing known for 1199-1200.
Coinage
The bishops of Verden had market, toll and mint rights at Verden (late 10th-century royal grant; not re-checked here).
The host
Ministeriales and vassals of the see; castles of Rotenburg and Verden. No figures.
Places of note
- Rotenburg castle: built by Bishop Rudolf in 1195 against Bremen
Where the sources disagree
- campaign notes do not mention Verden's side. The Speyer declaration of 28 May 1199 names Bishop Rudolf of Verden among Philip's princes (de.wikipedia Speyerer Fürstenerklärung).
Evidence: Only Rotenburg (1195) and the Speyer list are firm. His start date and family are not checked here.
On the map: The outline is a rough block around Verden and Rotenburg; the see's rights were scattered and its border with Bremen and the Welf lands is approximate.
