Charly 9 (2015)

Charles IX was the unluckiest King of all the monarchs of France.
At the age of 22, to please his mother Catherine de' Medici, he orders the St. Bartholomew's Day Massacre, which horrified all Europe.
Later, appalled by the enormity of his crime, he lapsed into insanity. Bleeding profusely, reduced to mere skin and bones, by the end of his life he was hated by all of Europe... Although, at one time he did have a good heart.
Charly 9 is a complete story.
