 The annexation to the French Republic also brought its attendant new territorial order.Merely by chance, the villages each side of the Glan that now make up Nanzdietschweiler remained asunder, for the river now formed the boundary between the Departments of Mont-Tonnerre (or Donnersberg in German) and Sarre.Dietschweiler and Nanzweiler on the left bank now belonged to the "Mairie" (“Mayoralty”) of Glan-Münchweiler, the Canton of Waldmohr, the Arrondissement of Saarbrücken and the Department of Sarre, while the centres that later became Nanzdiezweiler on the right bank found themselves in the "Mairie" of Obermohr (later Niedermohr), the Canton of Landstuhl, the Arrondissement of Zweibrücken and the Department of Donnersberg.
