 Weiler passed to the Mainz Cathedral Chapter in 1438 and remained in its hands until French Revolutionary troops occupied the Rhine’s left bank in 1792 to 1794.The Treaty of Campo Formio ended this arrangement when in 1797 the river Nahe became the boundary between the French departments of Mont-Tonnerre (Donnersberg) and Rhin-et-Moselle (Rhein-Mosel).The Congress of Vienna eventually assigned Weiler to the Kingdom of Prussia and in 1816, Bingen passed to the Grand Duchy of Hesse-Darmstadt.
