This post presents the data for the mass murders by the Nazi regime and its allies, by Communist regimes and their allies, and by other governments. This week is an especially appropriate time to reflect on mass murder by government. Kristallnacht was 84 years ago today, November 9, 1938. Two days ago, November 7, was the National Day for the Victims of Communism.
During the 20th century, governments murdered over 200 million people. This figure excludes battle deaths from wars. The tables below are from my just-published article Guns Kill People, and Tyrants With Gun Monopolies Kill the Most, 25 Gonzaga Journal of International Law 29 (2021). The data cover 1900 to 1987 and are mainly based on the scholarship of the late University of Hawaii political science professor Rudolph J. Rummel. The few instances in which different figures are used are explained in my article.
The tables below do not used the word "genocide," because that term, as defined in the Convention on the Prevention and Punishment of the Crime of Genocide, is too narrow. At the insistence of Josef Stalin, the Genocide Convention applies to some mass murders by government (e.g., targeting racial, ethnic, or religious groups) but not to others (e.g., targeting victims for class warfare or ideological reasons). Hence, prof. Rummel coined the term "democide" to describe noncombat mass murders for any reason.
