Electorate of Hesse
The Electorate of Hesse (German: Kurfürstentum Hessen), also known as Hesse-Kassel or Kurhessen, was the title used for the former Landgraviate of Hesse-Kassel after an 1803 reform where the Holy Roman Emperor elevated its ruler to the rank of Elector, thus giving him a vote in any future elections to the emperorship. When the Holy Roman Empire was abolished in 1806, William I, Elector of Hesse, chose to retain the title of Elector, even though there was no longer an Emperor to elect.
