International Criminal Tribunal for the former Yugoslavia (ICTY)The International Criminal Tribunal for the former Yugoslavia (ICTY) was a United Nations court of law that dealt with war crimes that took place during the conflicts in the Balkans in the 1990s. During its mandate, which lasted from 1993 - 2017, it irreversibly changed the landscape of international humanitarian law, provided victims an opportunity to voice the horrors they witnessed and experienced, and proved that those suspected of bearing the greatest responsibility for atrocities committed during armed conflicts can be called to account.
