Top 10 of the most deadly leaders in history

King Leopold II–10 Million

Leopold II ruled as the second King of the Belgians from 1865 until 1909, and he was also responsible for the deaths of millions in his quest to establish the Congo Free State. After seizing control of the Congo, he put its people to work (against their will). He brutalized the population in his campaign to strip the area of its ivory, rubber, and other natural resources. Leopold tasked his commanders with using violence and whatever means necessary to accomplish his goals.
