The correct answer is: "nazi leaders"
The Nuremberg Trials were organized by the victorious Alllied forces (US, UK, URSS and France) after WWII in the German city of Nuremberg. Political, judicial, military, and economic leaders from Nazi Germany who had taken part in the Holocaust or in other war crimes were judged there, for commiting crimes against humanity, under the provisions of international law and of war law codes.
