The Geneva Conventions comprise four treaties, and three additional protocols, that establish the standards of international law for the humanitarian treatment of war. The singular term Geneva Convention denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–45), which updated the terms of the first three treaties (1864, 1906, 1929), and added a fourth treaty.
The articles of the Fourth Geneva Convention (1949) extensively defined the basic, wartime rights of prisoners (civil and military); established protections for the wounded; and established protections for the civilians in and around a war-zone. The treaties of 1949 were ratified, in whole or with reservations, by 195 countries.
Moreover, the Geneva Convention also defines the rights and protections afforded to non-combatants, yet, because the Geneva Conventions are about people in war, the articles do not address warfare proper — the use of weapons of war — which is the subject of the Hague Conventions (First Hague Conference, 1899; Second Hague Conference 1907), and the bio–chemical warfare Geneva Protocol (Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or other Gases, and of Bacteriological Methods of Warfare, 1929).
