One thing was for certain during WWII, the Nazis were committing all sorts of war crimes in occupied areas throughout Europe. As early as 1942 the Allies began trying to figure a way to hold them accountable, so sure were they that the Nazis would be defeated.
By August 1945 the Allies all agreed to the London Charter that set out the legal argument for the military tribunals that were going to take place where the highest tanking and most foul offenders would be brought to justice. The limits the placed on themselves were that the tribunals would only deal with the European Axis powers and that they would not take into account any acts that occurred before September 1, 1939.
Where the trials would take place was the next consideration. The German city of Leipzig was considered as well as the country of Luxembourg, for a time Berlin itself was even considered. Instead the historic German city of Nuremberg was chosen for a number fo reasons. First was that the Palace of Justice was still standing, something not said for many German cities. This building was large enough to hold the proceedings and also had a prison attached to it, which was handy. Also Nuremberg was considered the birthplace of the Nazi Party. What more fitting place for the trials to take place?
The trials at Nuremberg opened on November 19, 1945 with its last official acts occurring on October 1st, 1946. During this time much was uncovered as to the origins of the war and the depths of the crimes committed by the regime. While the focus of the main tribunal was the 24 major criminals and seven organizations (including the Gestapo and the SS) it also set the stage for numerous smaller proceedings where hundreds of lesser criminals were brought to justice.
The picture above is of a visitor pass that allowed the hold to sit in and view the trial. Imagine how it would have felt to sit there during the trials and hear men justify their evil and the death of over 40 million people. On second thought, I think I will pass on the visitor pass.
