The genesis of the Nuremberg Trials can be traced to the growing Allied awareness during the war of the systematic nature of Nazi atrocities. As Allied forces advanced into Nazi-occupied territory in 1944 and 1945, they encountered evidence of crimes that defied comprehension: death camps designed for industrial-scale murder, medical experiments on human subjects, the systematic starvation of prisoners of war, and the deliberate targeting of civilian populations. The liberation of concentration camps like Bergen-Belsen, Dachau, and Auschwitz provided incontrovertible proof of genocide and created a moral imperative for accountability that transcended traditional notions of victor's justice.
