Twenty years ago, on 11 June 1977, the plenipotentiaries of over a hundred States and several national liberation movements signed the Final Act of the Diplomatic Conference on the Reaffirmation and Development of International Humanitarian Law Applicable in Armed Conflicts. This Conference had been convened by the government of Switzerland, the depositary State of the Geneva Conventions. After four sessions held between 1973 and 1977, themselves preceded by several years of preparatory work, the Conference drew up two Protocols additional to the Geneva Conventions of 12 August 1949, relating to the protection of the victims of international armed conflicts (Protocol I) and of noninternational armed conflicts (Protocol II).
