Günther von Schwarzburg
During the German succession crisis of 1347–1349, Count Günther and Karl, King of Bohemia, vie to succeed Ludwig the Bavarian as Holy Roman Emperor. Günther is supported by Rudolf, while Asberta intrigues for her son Karl by manipulating Rudolf’s daughter Anna. Asberta poisons Günther and then kills herself; Karl secures the throne and marries Anna.
