The Greek genocide took place in Anatolia.
Historian William Rubinstein argues that the origin of 20th-century genocides can be traced back to the collapse of the elite structure and normal modes of government in parts of Europe following World War I, commenting:The 'Age of Totalitarianism' included nearly all of the infamous examples of genocide in modern history, headed by the Jewish Holocaust, but also comprising the mass murders and purges of the Communist world, other mass killings carried out by Nazi Germany and its allies, and also the Armenian genocide of 1915
 Many instances of such crimes of genocide have occurred when racial, religious, political and other groups have been destroyed, entirely or in part
