Nazi war criminals were individuals who committed war crimes and crimes against humanity during the Nazi regime in Germany during World War II. These crimes included the systematic extermination of millions of Jews and other minority groups in the Holocaust, as well as the murder and mistreatment of prisoners of war, political opponents, and civilians in concentration camps and elsewhere. Notable Nazi war criminals included Adolf Eichmann, a key architect of the Holocaust, and Josef Mengele, a doctor who conducted inhumane experiments on prisoners at Auschwitz-Birkenau. After the war, numerous Nazi leaders and collaborators were brought to justice in trials, such as the Nuremberg Trials, and some were sentenced to death or life in prison. The pursuit of Nazi war criminals continued for decades after the war, with many individuals being hunted down and brought to trial in countries around the world.
