German mediatization
The capital of the electorate was Cologne. Conflicts with the citizens of Cologne caused the Elector to move to Bonn. The Free Imperial City of Cologne was recognized after 1475, thus removing it from even the nominal secular authority of the Elector. Cologne and Bonn were occupied by France in 1794. The right bank territories of the Electorate were secularized in 1803 during the German mediatization.
