Quick Summary

A war crime is a serious violation of the laws and customs of war, as defined by international law and treaties. These offenses have evolved in definition, particularly since World War I, and can include acts like murder, torture, and mistreatment of prisoners. Modern definitions are broad, encompassing actions by both military personnel and civilians.12

Crimes against peace, war crimes, and crimes against humanity were key categories established by the Nuremberg tribunal after World War II. Crimes against peace involve the preparation and initiation of aggressive war. War crimes are violations of the laws and customs of war, while crimes against humanity include widespread or systematic attacks against civilian populations, such as murder, extermination, and persecution. International tribunals, like those for Yugoslavia and Rwanda, and the International Criminal Court, have further codified and prosecuted these offenses.1345
