Leopold II of Belgium
Number 3 on the list of evil villains with royal lifestyles is Leopold the second, who was in fact a real king, who ruled Belgium for 44 years.
Overthrowing a king in that period was a thing not so achievable and Leopold II maintained his supremacy at the expense of not one nation but two.
In his years of ruling Leopold commissioned Congo to be at his expenses, making it a free state that he managed by armed forces and mercenaries.
This made him very rich, taking from Congo every riches he could find, these being under the form of ivory, rubber and many more.
The villain killed million of people in the Congo just to make his fortunes while the money was used for his massive explorations, his lavish lifestyle and some for making Belgium a rich infrastructure.
