Schleiden

A castle lordship in the upper Olef valley of the Eifel, held by a cadet line of the Blankenheim house.

The castle is named in 1121 or, by another account, 1198. Its lords keep quarrelling with the Premonstratensian canons of Steinfeld over property and usually have to give way.

Confidence

de.wikipedia 'Herrschaft Schleiden' (its early generations are undated and partly garbled).

Overlord

None pinned for 1200: the counts of Luxembourg become lords of the fief only in 1271, and the Jülich fief relations are undated.

What it holds

  • Schleiden castle on the Olef
  • The villages of the upper Olef and Urft round Schleiden, Gemünd, Kall and Hellenthal (bounds not pinned)
  • Rights disputed with the abbey of Steinfeld

How it was acquired

By the twelfth-century division between the sons of Gerard II of Blankenheim and Schleiden.

Allies and rivals

Kin of the lords of Blankenheim. Rivals: the canons of Steinfeld. Neighbours: the lords of Reifferscheid and Hengebach and the count of Jülich.

How things stand that morning

Held by the Schleiden line; no holder's name or act is pinned for 1199-1200, and no side in the throne war is recorded.

Wealth

Forest, upland pasture and the dues of a poor upland; iron and lead are worked in the Eifel valleys round it.

Military

One castle and Eifel vassals; no recorded campaign in 1198-1199.

Threats

  • Steinfeld's lawsuits
  • The reach of the count of Jülich into the northern Eifel

Places of note

  • Schleiden castle: The lords' castle on the Olef

Where the sources disagree

Evidence: One family article with undated early generations; the castle's first mention is given as 1121 or 1198.

On the map: The lordship's 1200 bounds are not recorded; the block follows the upper Olef and Urft valleys.
