Officially, the Third Reich lasted only 12 years. The Instrument of Surrender was signed by representatives of the German High Command at Berlin, on 8 May 1945. The war in Europe had come to an end. The defeat of Germany in World War II marked the end of the Nazi Germany era. The party was formally abolished on 10 October 1945 by the Allied Control Council and denazification began, along with trials of major war criminals before the International Military Tribunal (IMT) in Nuremberg. Part of the Potsdam Agreement called for the destruction of the Nationalist Socialist Party alongside the requirement for the reconstruction of the German political life. In addition, the Control Council Law no. 2 Providing for the Termination and Liquidation of the Nazi Organization specified the abolition of 52 other Nazi affiliated and supervised organisations and prohibited their activities. The denazification was carried out in Germany and continued until the onset of the Cold War.
