The Carolingian royal abbey of Prüm in the Eifel had estates reaching from the Rhine to Brittany and the Netherlands; its rent-roll of 893 lists about 1,500 farms in over 400 places.
In 1200 it is lord of the Prüm country in the western Eifel and of scattered estates, ruled by an abbot of the comital house of Vianden. Frederick II will make it a principality in 1222.

Abbot 1184-1212, of the counts of Vianden. His successor will be Caesarius of Milendonk (1212-1216), who as a retired monk in 1222 makes the famous commented copy of the abbey's rent-roll of 893.
What it holds
- Prüm: the abbey and the market at its gate, with the surrounding lands in the western Eifel
- Scattered estates and rents along the Rhine, the Moselle and in the Low Countries (much reduced since 893)
How it was acquired
Royal foundation (refounded by Pippin in 752) and Carolingian endowment; principality in 1222; full imperial estate in 1299.
How things stand that morning
Gerhard holds the abbey and its Eifel lands. His family ties to Vianden protect and threaten it at once.
Wealth
Eifel farms, forests and pigs; rents from distant estates; pilgrims to the abbey's relics.
Threats
- The counts of Luxembourg
- Trier's ambitions
Advocates and rivals
The counts of Luxembourg, with whom the abbey quarrels; the counts of Vianden, the abbot's own house; the archbishop of Trier, who will try to absorb the abbey.
Where the sources disagree
Evidence: The abbots and the abbey's status are attested; its block of land around Prüm in 1200 is drawn as a territory around the town.
On the map: Drawn as a 10 km territory around the abbey; the scattered estates are not drawn.
