When the International Military Tribunal on October 1, 1946, pronounced judgment on 22 Germans accused as major war criminals, a truly historic trial came to an end. It was the first such tribunal constituted by a number of Great Powers and in the interests of all the United Nations. Since the beginning of the modern state system, this was the first time that die leaders of a Great Power, its statesmen, soldiers, journalists and propagandists were held accountable for crimes against peace and humanity, which themselves were substantial innovations or developments. Ordinary war crimes, usually within the province of domestic military courts, were also for the first time tried by an international tribunal.
