medium

First count of Pyrmont. The castle (the Schellenburg) was built by Archbishop Philip of Cologne in 1180 (another account says 1184) to guard the border of his new duchy of Westphalia along the Emmer, and given to the Schwalenberg counts as a fief.

Overlord

The archbishop of Cologne, from whom Pyrmont is held as a fief.

What it holds

  • Pyrmont castle (the Schellenburg) in the Emmer valley, a Cologne fief
  • Lands round Pyrmont and the Emmer (Lügde becomes the counts' seat only in 1376)

How it was acquired

Fief of Cologne to the Schwalenberg house (1180/84); his own line from 1194.

Allies and rivals

His Schwalenberg and Waldeck kin; the archbishop of Cologne. Neighbours: the Everstein counts and Hameln (nse), Lippe, Corvey.

How things stand that morning

Holds Pyrmont as Cologne's vassal. His own side in the throne war is not pinned; his kinsmen of Schwalenberg and Waldeck and his overlord are Otto's. Across his borders: Hameln and the Everstein lands (nse) to the east and north, Schwalenberg and Lippe to the west, Corvey to the south.

Wealth

Manors in the Emmer valley; the mineral springs of Pyrmont (their medieval use is not pinned here).

Military

Pyrmont castle. No numbers.

Threats

  • The Welf lords across the Weser hills
  • Everstein

Places of note

  • Pyrmont castle (Schellenburg): Cologne castle of 1180/84 on the Emmer.

Where the sources disagree

  • de.wikipedia's county article dates the castle to 1180; other accounts give 1184.

Evidence: The split of 1194 and Gottschalk's dates come from the county article; the extent of his lands in 1200 is rough.

On the map: Rough.
