I have a list of fun lunatic rulers!

Charles VI of France thought his bones were made of glass.


Ferdinand I of Austria: Was the Emperor of the Holy Roman Empire. The only issue was that he was so inbred he could not speak or do basic tasks.  The only full sentence he ever said was “I am the Emperor, and I want dumplings.” Gotta love the Hapsburgs! 

Caligula: Declared war on the sea. That is all.

Joanna, Queen of Castile AKA Joanna La Loca  (the Mad): Lost her husband early in their marriage and then had a mental breakdown that was most likely schizophrenia. She kept opening her husband's crypt to see him and lay with him.
