Geneva Convention IV

Geneva Convention IV, formally the Geneva Convention relative to the Protection of Civilian Persons in Time of War, was adopted on 12 August 1949 and entered into force on 21 October 1950. It is the fourth of the four 1949 Geneva Conventions and the first to focus specifically on civilians, a gap exposed by the mass abuses of World War II. The Convention has achieved near-universal ratification, binding virtually every state in the world.

The treaty contains 159 articles organized around the protection of "protected persons" — civilians who find themselves in the hands of a party to a conflict or an occupying power of which they are not nationals. Key obligations include:

• Common Article 3, shared with the other three Conventions, sets a minimum standard for non-international armed conflicts, prohibiting murder, torture, hostage-taking, and humiliating treatment.
• Article 27 guarantees respect for the person, honor, family rights, and religious convictions of protected persons.
• Article 33 prohibits collective punishment and reprisals against civilians.
• Article 49 forbids individual or mass forcible transfers and deportations, and bars an occupying power from transferring parts of its own civilian population into occupied territory.
• Articles 47–78 govern the law of occupation, including the duties of an occupying power regarding food, medical care, public order, and judicial guarantees.
• Grave breaches (Article 147) — including willful killing, torture, and unlawful deportation — 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 of 1977 and Additional Protocol III of 2005. The International Committee of the Red Cross (ICRC) serves as its guardian and conducts visits to detainees and occupied populations under its terms.
