The devastation left by World War II, particularly the atrocities of the Holocaust, prompted the international community to confront an unprecedented question: how should justice be served for crimes committed on such a massive scale? As Allied forces liberated Nazi-occupied territories, they uncovered the full horror of concentration camps, mass executions, and the systematic extermination of millions. These revelations fueled the resolve of the Allied leaders to hold the Nazi regime accountable through a legal process unlike any that had come before.
The idea of prosecuting war crimes was not new, but the scale and coordination of the Nazi crimes required an entirely different approach. Traditional military justice or ad hoc tribunals would not suffice. Instead, the Allies sought to establish an international tribunal that would not only punish the perpetrators but also set a legal precedent for crimes against humanity, crimes against peace, and war crimes. This marked a significant shift in international law and diplomacy, as sovereign leaders and military officials could now be held individually responsible for actions carried out under state authority.
In 1945, representatives from the United States, the United Kingdom, the Soviet Union, and France convened in London to draft the legal framework for the upcoming trials. The result was the London Charter of the International Military Tribunal (IMT), which laid out the charges, procedures, and rules governing the trial of the major Axis war criminals. The city of Nuremberg in Germany was chosen as the trial site not only for its symbolic value—having hosted many Nazi rallies—but also for its intact courthouse and prison facilities.
