secundogeniture of the Bavarian branch of the House of Wittelsbach. As the archbishop in this period usually also held the Bishopric of Münster (and often the Bishopric of Liège), he was one of the most important princes of northwestern Germany. From 1597 until 1794, Bonn was the residence the Elector, and consequently the capital of the Electorate. 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.
