Most of the senior leaders of the camp, including Rudolf Höss, the longest-standing commandant of the camp, were turned over to the Polish authorities in 1947 following their participation as witnesses in the Nuremberg Trial. Subsequently, the accused were tried in Kraków and many sentenced to death for violent crimes and torturing of prisoners. Only "SS-Untersturmführer" Hans Münch was set free, having been acquitted of war crimes. That original trial in Poland is usually known as the first Auschwitz Trial.
