The main purpose of the Nuremberg Trials after World War II was to hold accountable key leaders of Nazi Germany for crimes against humanity, war crimes, and genocide. Conducted from 1945 to 1946, the trials aimed to ensure that individuals, rather than nations, would be punished for atrocities committed during the war. The trials established important legal precedents regarding war crimes and addressed the moral obligation to uphold human rights. They served as a platform to document evidence of Nazi atrocities, contributing significantly to international law and the principles of justice, and aimed to deter future violations of human rights.
