List of genocides by death toll

This list of genocides by death toll includes death toll estimates of all deaths that are either directly or indirectly caused by genocide. It does not include non-genocidal mass killing such as the Destruction under the Mongol Empire, the Thirty Years War, Japanese War Crimes, the Atrocities in the Congo Free State, the 1965–1966 Indonesian Politicide or the Great Leap Forward.
The United Nations Genocide Convention defines genocide as "acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group". Various other definitions can be found in scholarly literature, but they have no legal weight.
