 Nußbach thereby belonged between 1801 and 1814 to France, administratively to the "Mairie" (“Mayoralty”) of Becherbach, the Canton of Lauterecken, the Arrondissement of Kaiserslautern and the Department of Mont-Tonnerre (or Donnersberg in German).In the regional new order laid out after the time of French rule by the Congress of Vienna, the village passed to the Kingdom of Bavaria, for the Palatinate had become an exclave of that state.Within this "bayerischer Rheinkreis" (“Bavarian Rhine District”), Nußbach at first belonged to the "Bürgermeisterei" (“Mayoralty”) of Becherbach, but later became the seat of its own "Bürgermeisterei" in the Canton of Lauterecken and the "Landkommissariat" of Kusel.
