After World War 2, trials known as the Nuremberg Trials were held from 1945-1946 to prosecute Nazi war criminals. The trials were conducted in Nuremberg, Germany by judges from the Allied powers of the US, USSR, UK and France. Key Nazi officials were charged with conspiracy, crimes against peace, war crimes and crimes against humanity. Twelve prominent Nazis were sentenced to death for their direct role in the Holocaust, while others received prison sentences or no punishment. Later trials against Nazis continued in Germany and other countries in the postwar period.
