Which Monarch from history would you choose to be?Watch
I am not sure, but would choose someone who: was very secure in their reign/rule (i.e. you could do what you like without the risk of revolution), was extremely rich, had great military power so that no foreign force could come and depose you, etc.
That's a lot of Elizabeths...
EDIT: Elizabeth Woodsville was f***ing badass. I thought Elizabeth I was but her great grandmother owns that title.
