The Fourth Geneva Convention, formally the Convention (IV) relative to the Protection of Civilian Persons in Time of War, was adopted in Geneva on 12 August 1949 and entered into force on 21 October 1950. It is one of the four 1949 Geneva Conventions and was the first to focus specifically on civilians, a gap made painfully clear by the mass civilian harm of World War II. The Convention has near-universal ratification, with all UN member states party to it.
The treaty applies to international armed conflicts and to situations of belligerent occupation. Its Common Article 2 triggers full application in declared war or any other armed conflict between High Contracting Parties, while Common Article 3 sets a minimum humanitarian baseline that also binds parties in non-international armed conflicts.
Key protections include:
- A prohibition on violence to life and person, torture, hostage-taking, and humiliating treatment of "protected persons" (Article 3, Article 27).
- A ban on collective penalties, reprisals against civilians, and pillage (Article 33).
- Rules on internment and treatment of aliens in a party's territory (Articles 35–46).
- An extensive regime on occupied territories (Articles 47–78), including the prohibition on individual or mass forcible transfers and deportations of protected persons (Article 49), and the rule that the Occupying Power "shall not deport or transfer parts of its own civilian population into the territory it occupies" (Article 49(6)).
- Protections for hospitals, medical personnel, and the wounded.
"Grave breaches" under Article 147 — including wilful killing, torture, unlawful deportation, and taking of hostages — trigger universal jurisdiction and an obligation on all states parties to search for and prosecute or extradite suspects.
The Convention is supplemented by Additional Protocols I and II (1977) and Protocol III (2005). The International Committee of the Red Cross (ICRC) serves as its guardian and publishes authoritative commentaries. The International Court of Justice's 2004 Wall advisory opinion and multiple ICTY judgments have applied GC IV in practice.
Example
In its 2004 advisory opinion on the *Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory*, the International Court of Justice held that the Fourth Geneva Convention applies to territories occupied by Israel since 1967.
Frequently asked questions
