 It is believed that the Prüm proprietary church lost its independence under Archbishop of Mainz Adalbert II (1138-1141) and was placed under Mainz ecclesiastical jurisdiction by reason of Verdun's proprietary church rights and the Frankish Imperial partitions in the 9th century.Both Medard’s and Odenbach’s churches thereby passed into the ownership of the monastery at Disibodenberg.Under Archbishop Gerlach of Mainz (1353-1371), the Church of Odenbach got its independence back on 15 June 1367, and has held onto it without interruption ever since.
