The major war criminals Goering, Hess, von Ribbentrop, and others were sentenced by an international military tribunal in Nuremberg for certain crimes or groups of crimes which had been formulated prior to the trial in a charter signed in August, 1945, by the representatives of the United States, France, Britain, and Russia. In the Charter of the International Military Tribunal adopted in London three major categories of delinquency had been set up dealing with crimes against peace, war crimes, and crimes against humanity. Crimes against peace were to consist of acts such as planning, preparing, initiating or waging a war of aggression in violation of international treaties or participating in a common plan or conspiracy for the accomplishment of the foregoing. War crimes were to consist of violations of the laws or customs of war and were to include, among others, murder, ill-treatment or deportation to slave labor, ill-treatment of prisoners of war, killing of hostages, and wanton destruction of cities not justified by military necessity. As crimes against humanity were to be considered such acts as exterminations, enslavement, deportation of any civilian population before or during the war or any kind of persecution if the latter had occurred in execution of or in connection with any other crime under the jurisdiction of the tribunal.
