While Bad Münster belonged from the Middle Ages to the Knights of Löwenstein and the Rhinegraves, and after Napoleon was driven out, to Prussia’s Rhine Province (under the terms laid out by the Congress of Vienna) from 1815 to 1945, Ebernburg belonged throughout the Middle Ages to a whole succession of lords from the Counts of Saarbrücken to the Counts of Leiningen, the Raugraves, the Counts of Sponheim, the Counts of Veldenz, Electoral Palatinate and the Lords of Sickingen before the Revolutionary, later Napoleonic, French took over. After Napoleonic times, Ebernburg belonged (again, under the terms laid out by the Congress of Vienna) to the Kingdom of Bavaria, and after the German Revolution to the Free State of Bavaria, and was that state’s northernmost municipality, lying in Bavaria’s new exclave in the Palatinate. The two constituent communities’ separate histories may no longer live on politically, but they are still reflected in ecclesiastical administration, with Bad Münster belonging to the Evangelical Church in the Rhineland and the Roman Catholic Diocese of Trier and Ebernburg on the other hand belonging to the Evangelical Church of the Palatinate and the Roman Catholic Diocese of Speyer.
