An international tribunal for Nazi war criminals. The trials were complex and controversial, there being few precedents for using international law relating to the conduct of states to judge the activities of individuals. The charges were: conspiracy against peace, crimes against peace, violation of the laws and customs of war, crimes against humanity. As a result of the trials several Nazi organizations, such as the Gestapo and the SS, were declared to be criminal bodies. Individual judgements against the 24 war-time leaders included death sentences, imprisonment, and not guilty. Ten prisoners were executed, while Goering and Ley committed suicide. Rudolf Hess was sentenced to life-imprisonment.
