German mediatization
The elector palatine's seat was conferred on the duke of Bavaria in 1621, but in 1648, in the wake of the Thirty Years' War, the elector palatine was restored, as the eighth elector. Electorate of Hanover was added as a ninth elector in 1692. The whole college was reshuffled in the German mediatization of 1803 with a total of ten electors, a mere three years before the dissolution of the Empire.
