Note: Even though the title of Elector was largely meaningless after the end of the Holy Roman Empire, with no emperor to elect anymore, the Elector of Hesse-Kassel, Wilhelm I, chose to keep the title, preferring it over the offer of Grand Duke from the Congress of Vienna, seeing it as a downgrade from the electoral title.
