Prüm Abbey
The Abbey ruled over a vast hinterland comprising dozens of towns, villages and hamlets. Its abbot enjoyed the status of a prince ("Fürst") of the Holy Roman Empire, and as such had seat and vote on the Ecclesiastical Bench of the College of ruling princes of the Imperial Diet. After 1574, the archbishops-electors of Trier became the "perpetual administrators" of Prüm Abbey which, while preserving its princely status, became, de facto, an adjunct of Trier.
