Electorate of Trier
Hillscheid itself was largely destroyed in the Thirty Years' War, recovering rather quickly, however, and from 1683, it had a chapel. It only remained part of the parish of Vallendar until 1812. For the most part, Vallendar had two lords: Sayn-Wittgenstein and the Electorate of Trier. Once France had conquered the areas on the Rhine’s left bank and the Electorate of Trier had been beaten, the Electorate’s former territories on the Rhine’s right bank, and thereby also Vallendar and Hillscheid, passed under Napoleon to the Duchy of Nassau-Weilburg in 1803 as a result of the so-called "Reichsdeputationshauptschluss".
