Herzogtum Westfalen
"The Elector's lands west of the Rhine were occupied by the French in 1795 and annexed. The Archbishopric was left vacant on the death of the Elector in 1805. The lands east of the Rhine were secularised as the Duchy of Westphalia in 1803, which was given to the Landgrave of Hesse-Darmstadt".
