Nazi war crimes refer to the atrocities committed by the Nazi regime during World War II, primarily against Jews, Romani people, and other targeted groups. These crimes included mass killings, forced labor, and inhumane medical experiments, which were part of a broader agenda of genocide known as the Holocaust. The Nuremberg Trials after the war sought to bring Nazi leaders to justice for these crimes against humanity. The trials established legal precedents for prosecuting war crimes and highlighted the importance of accountability for actions taken during wartime, influencing international law and human rights standards.
