During Napoleon's campaigns, as French subjects, men from Jettenbach were required to serve as soldiers for the Napoleon's empire, doing so throughout Europe. The empire's downfall brought Jettenbach renewed burdens, with German troops stationed in the village, and the presence of Russian troops during their post-war withdrawal. Under the post-war settlement devised by the Congress of Vienna, which took effect in 1816, the Palatinate was annexed to the Kingdom of Bavaria. Thenceforth, Jettenbach belonged to the canton of Wolfstein and the "Landkommissariat" of Kusel. Only Kollweiler (until about 1890), and Albersbach (until 1969), remained in the "Bürgermeisterei" ("mayoralty") of Jettenbach. Jettenbach remained part of the canton of Wolfstein into the 20th century.
