On 28 April 1945, Mussolini was captured and executed by Italian communist partisans. On 30 April 1945, Hitler committed suicide. Shortly afterwards, Germany surrendered and the Nazi regime was systematically dismantled by the occupying Allied powers. An International Military Tribunal was subsequently convened in Nuremberg. Beginning in November 1945 and lasting through 1949, numerous Nazi political, military and economic leaders were tried and convicted of war crimes, with many of the worst offenders being sentenced to death and executed.
