A crime against humanity, such as deliberate killing of civilians or mistreatment of prisoners, committed during a war. War crimes are defined in a number of internationally accepted treaties, including the Geneva Conventions. The most notorious example of war crimes in recent history were those committed by Nazi Germany during World War II. In 1946, at the Nuremberg Tribunal in Nuremberg, Germany, 24 leading Nazis were tried by the victorious allied powers for war crimes. Nineteen were found guilty and 12 were sentenced to death. The subject came up again in the context of the 1992-95 war in Bosnia, where atrocities perpetrated by Serbs against Muslim civilians led to war crimes charges being brought against Serb leaders. Since its creation in 2002, the International Criminal Court in the Hague has the authority to prosecute the perpetrators of war crimes committed on or after that date.
