During the time of annexation of the German lands on the Rhine’s left bank by France, Haschbach belonged within the French First Republic – and then later within the First French Empire under Napoleon – to the Department of Sarre, the Arrondissement of Birkenfeld, the Canton of Kusel and the "Mairie" (“Mayoralty”) of Quirnbach. After the French were driven out, Haschbach then belonged within the Kingdom of Bavaria (to which the Congress of Vienna had awarded the Palatinate) to the "Landkommissariat" (district) and Canton of Kusel, and to a "Bürgermeisterei" (“mayoralty”) whose name changed according to where the mayor lived – sometimes in Godelhausen and sometimes in Theisbergstegen (the former is today a constituent community of the latter).
