The term "crimes against humanity" has been applied to a wide range of acts and is often seen as broader than the other three mass atrocity crimes. While crimes against humanity can include many acts that also constitute war crimes, genocide, or ethnic cleansing, it bears distinguishing characteristics. Unlike war crimes, crimes against humanity may be committed in times of war or peace and can only be committed against civilian populations. Unlike genocide, the acts need not be targeted against a specific group. Despite not being the subject of a dedicated treaty, the prohibition against crimes against humanity is considered
customary international law and an established
norm, meaning it is binding on all states without exception. The term has a long history of use both in political and legal contexts. Crimes against humanity, and similar terms, were used in the 18th century and early 19th century to describe
slavery and atrocities committed as part of
colonialism. Since then the term has been used and defined in similar, but variant ways by the
Nuremberg Tribunal,
Tokyo Tribunal,
International Criminal Tribunal for the former Yugoslavia,
International Criminal Tribunal for Rwanda, and International Criminal Court. The statute defines crimes against humanity as any of the following acts when committed as part of a widespread or systematic attack directed against any civilian population, with knowledge of the attack: :(a) Murder. :(b) Extermination; :(c) Enslavement; :(d) Deportation or forcible transfer of population; :(e) Imprisonment or other severe deprivation of physical liberty in violation of fundamental rules of international law; :(f) Torture; :(g) Rape, sexual slavery, enforced prostitution, forced pregnancy,
enforced sterilization, or any other form of sexual violence of comparable gravity; :(h) Persecution against any identifiable group or collectivity on political, racial, national, ethnic, cultural, religious, gender...or other grounds that are universally recognized as impermissible under international law, in connection with any act referred to in this paragraph or any crime within the jurisdiction of the Court; :(i) Enforced disappearance of persons; :(j) The crime of
apartheid; :(k) Other inhumane acts of a similar character intentionally causing great suffering, or serious injury to body or to mental or physical health. == Genocide ==
