Гессен-Дармштадт
After 1795, the electorate's territories on the left bank of the Rhine were occupied by France and were formally annexed in 1801. Cologne was part of the "département" of Roer; Bonn was part of the "département" of Rhin-et-Moselle. The "Reichsdeputationshauptschluss" of 1803 secularized the rest of the archbishopric, giving the Duchy of Westphalia to the Landgraviate of Hesse-Darmstadt and Vest Recklinghausen to the Duke of Arenberg. Cologne was, however, reestablished as the seat of a Catholic archbishop in 1824, and is an archdiocese to the present day.
