hierarchical_section_title: Crimes against humanity / Term origins / First use
context_page_description: Crimes against humanity are certain acts that are purposely committed as part of a widespread or systematic attack directed against any civilian or an identifiable part of a civilian population. The first prosecution for crimes against humanity took place at the Nuremberg trials. Crimes against humanity have since been prosecuted by other international courts as well as in domestic prosecutions. The law of crimes against humanity has primarily developed through the evolution of customary international law. Crimes against humanity are not codified in an international convention, although there is currently an international effort to establish such a treaty, led by the Crimes Against Humanity Initiative.
  Unlike war crimes, crimes against humanity can be committed during peace or war. They are not isolated or sporadic events, but are part either of a government policy or of a wide practice of atrocities tolerated or condoned by a government or a de facto authority.
context_section_description: The term "crimes against humanity" was used by George Washington Williams in a pamphlet published in 1890 to describe the practices of Leopold II of Belgium's administration of the Congo Free State. In treaty law, the term originated in the Second Hague Convention of 1899 preamble and was expanded in the Fourth Hague Convention of 1907 preamble and their respective regulations, which were concerned with the codification of new rules of international humanitarian law. The preamble of the two Conventions referenced the "laws of humanity" as an expression of underlying inarticulated humanistic values. The term is part of what is known as the Martens Clause.
  On May 24, 1915, the Allied Powers, Britain, France, and Russia, jointly issued a statement explicitly charging for the first time ever another government of committing "a crime against humanity". An excerpt from this joint statement reads:
  In view of these new crimes of Ottoman Empire against humanity and civilization, the Allied Governments announce publicly to the Sublime Porte that they will hold personally responsible for these crimes all members of the Ottoman Government, as well as those of their agents who are implicated in such massacres.
  At the conclusion of the war, an international war crimes commission recommended the creation of a tribunal to try "violations of the laws of humanity". However, the US representative objected to references to "law of humanity" as being imprecise and insufficiently developed at that time and the concept was not pursued. 
  Nonetheless, a UN report in 1948 referred to the usage of the term "crimes against humanity" in regard to the Armenian massacres as a precedent to the Nürnberg and Tokyo Charters. On May 15, 1948, the Economic and Social Council presented a 384-pages report prepared by the United Nations War Crimes Commission (UNWCC), set up in London (October 1943) to collect and collate information on war crimes and war criminals.  The report was in compliance to the request by the UN Secretary-General to make arrangements for "the collection and publication of information concerning human rights arising from trials of war criminals, quislings and traitors, and in particular from the Nürnberg and Tokyo Trials." The report had been prepared by members of the Legal Staff of the Commission. The report is highly topical in regard to the Armenian Genocide, not only because it uses the 1915 events as a historic example, but also as a precedent to the Articles 6 (c) and 5 (c) of the Nuremberg and Tokyo Charters, and thereby as a precursor to the then newly adopted UN Genocide Convention, differentiating between war crimes and crimes against humanity. By refereeing to the information collected during WWI and put forward by the 1919 Commission of Responsibilities, the report entitled "Information Concerning Human Rights Arising from Trials of War Criminals" used the Armenian case as a vivid example of committed crimes by a state against its own citizens. The report also noted that while the Paris Peace Treaties with Germany, Austria, Hungary and Bulgaria, did not include any reference to "laws of humanity", instead basing the charges on violations of "laws and customs of war", The Sèvres Peace Treaty with Turkey did so. In addition to the Articles 226–228, concerning customs of war (corresponding to Articles 228–230 of the Treaty of Versailles), the Sèvres Treaty also contained an additional Article 230, obviously in compliance with the Allied ultimatum of May 24, 1915 in regard to committed "crimes against humanity and civilization".
