At the Yalta Conference, the leaders of the allies had agreed that an international tribunal would try the main Nazi leaders, who were held responsible for the outbreak of the Second World War and for the war crimes committed during the conflict. This resolution was confirmed at the Potsdam Conference, which was held in July 1945.
After the end of the war, the devastation was so great and the war crimes that were coming to light so heinous that the Allies confirmed the determination that exemplary punishments be imposed on those responsible for the extermination of millions of human beings.
On August 8, 1945, representatives of the United States, France, Great Britain, and the Soviet Union signed the London Charter, a document that set out the principles and procedures by which the Nuremberg trials would be governed.
