Extermination is a crime against humanity that consists of "the act of killing on a large scale".[2] To be convicted of this crime, someone must play a role in a sufficiently-large scale killing of civilians, including those carried out by "the intentional infliction of conditions of life... calculated to bring about the destruction of part of a population".[3] It was first prosecuted at the International Military Tribunal in Nuremberg, and was included in the enumerated crimes against humanity in the Rome Statute.
