 At the time of the French annexation of the Rhine’s left bank in Napoleonic times, Selchenbach belonged to the Department of Sarre, the Arrondissement of Birkenfeld, the Canton of Kusel and the "Mairie" (“Mayoralty”) of Konken.After Napoleon was driven out, Selchenbach remained at first in the Birkenfeld district, but in 1816 it passed to the Kingdom of Bavaria, within which it was grouped into the "Bürgermeisterei" (“Mayoralty”) of Niederkirchen in 1818.During Bavarian times, Selchenbach, along with six other places in the Oster valley, belonged to the "Landcommissariat" and Canton of Kusel in this mayoralty.
