Summary: Being the product of a political will of the international society and public opinion, the jurisdictionalization of international criminal law is the result of a long process. It was only effectively put in place after the Second World War with the Nuremberg and Tokyo trials. Its development having been interrupted by the Cold War, it is finally, with the fall of the Soviet bloc and taking into account the atrocity of the crimes committed during recent conflicts, that this international criminal justice became a reality. Thus, in the 1990s, the International Criminal Tribunals (ICTs) appeared, but the last innovation in this field was undoubtedly the ICC, whose Statute was adopted on July 17, 1998 in Rome.
