International Humanitarian Law — Geneva Conventions & Laws of War

Key Concepts

International Humanitarian Law (IHL) — also called the Law of Armed Conflict (LOAC) or jus in bello — is the body of international law that governs the conduct of armed conflict. It seeks to limit the effects of war by protecting persons who are not or are no longer participating in hostilities, and by restricting the means and methods of warfare.

IHL is distinct from jus ad bellum — the law governing whether a state may lawfully resort to force (governed by the UN Charter). IHL applies regardless of whether the armed conflict is lawful or unlawful, or who started it.

Core purpose: Even in war, there are limits. IHL represents the international community's effort to balance military necessity with humanitarian imperatives.

Historical Background — Henry Dunant and the Red Cross

The modern IHL framework traces its origins to the Battle of Solferino (1859), in northern Italy, where Swiss businessman Henry Dunant witnessed approximately 40,000 soldiers left wounded and dying without adequate care. His 1862 book A Memory of Solferino (Un Souvenir de Solférino) sparked an international movement.

In February 1863, Dunant and four colleagues — Gustave Moynier, Louis Appia, Théodore Maunoir, and General Guillaume-Henri Dufour — held their first meeting in Geneva, Switzerland. This gathering is now recognised as the founding of the International Committee of the Red Cross (ICRC).

In August 1864, 12 nations signed the first Geneva Convention — binding armies to care for wounded soldiers regardless of nationality, and establishing the red cross on white background as the universal emblem for medical services.

The Four Geneva Conventions, 1949

After World War II, the 1864, 1906, and 1929 Geneva Conventions were revised and expanded. On 12 August 1949, four comprehensive conventions were adopted in Geneva:

Geneva Convention I (GC I) — Protection of Wounded and Sick in Armed Forces in the Field

• Protects wounded and sick soldiers on land.
• Mandates humane treatment; prohibits killing or abandoning wounded.
• Protects medical personnel, units, and transports bearing the red cross/crescent emblem.

Geneva Convention II (GC II) — Protection of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea

• Extends GC I protections to naval warfare.
• Protects hospital ships and their personnel.

Geneva Convention III (GC III) — Treatment of Prisoners of War

• Defines who qualifies as a Prisoner of War (POW).
• Mandates humane treatment, adequate food, shelter, and medical care.
• Prohibits torture, medical experiments, and public humiliation of POWs.
• Article 17: POWs need only give name, rank, date of birth, and service number.

Geneva Convention IV (GC IV) — Protection of Civilian Persons in Time of War

• The most extensive convention — protects civilians in occupied territories.
• Prohibits collective punishment, unlawful confinement, and deportation of civilians.
• Regulates occupation law — duties of an occupying power.

Universality: All four Geneva Conventions of 1949 have been ratified by 196 states — making them the most widely ratified treaties in the history of international law. India is a party to all four.

Common Article 3 — appearing identically in all four conventions — establishes minimum standards for non-international armed conflicts (civil wars): humane treatment of persons not taking part in hostilities, prohibition of murder, torture, and degrading treatment.

Additional Protocols, 1977

Two Additional Protocols adopted on 8 June 1977 significantly expanded IHL:

Protocol I (AP I) — Protection of Victims of International Armed Conflicts

• Strengthened protection for civilians in international conflicts.
• Codified the principles of distinction, proportionality, and precaution.
• Extended POW status to certain guerrilla combatants and national liberation movements.
• Established rules on methods of warfare: prohibition of attacks on civilian objects, starvation of civilians.

Protocol II (AP II) — Protection of Victims of Non-International Armed Conflicts

• The first treaty exclusively governing internal armed conflicts.
• Minimum standards for government forces and non-state armed groups in civil wars.
• Prohibits attacks on civilian populations, pillage, and acts of terrorism.

Protocol III (2005) — introduced the Red Crystal as an additional emblem alongside the Red Cross and Red Crescent.

Core Principles of IHL

Distinction

Parties to a conflict must at all times distinguish between civilians and combatants, and between civilian objects and military objectives. Attacks may only be directed at combatants and military objectives.

Proportionality

An attack is prohibited if it may be expected to cause incidental civilian loss or damage excessive in relation to the concrete and direct military advantage anticipated. Proportionality does not prohibit civilian casualties — it prohibits disproportionate civilian casualties.

Precaution

All feasible precautions must be taken to avoid and minimise civilian harm — including choice of means and methods of attack, and giving advance warning where possible.

Prohibition of Indiscriminate Attacks

Attacks that are not directed at specific military objectives, or that use means and methods that cannot be directed at a specific military objective, are prohibited (e.g., carpet bombing of cities, use of biological weapons).

Humane Treatment

Persons in the power of a party to the conflict — wounded, POWs, civilians — must be treated humanely at all times.

The ICRC — Role and Structure

The International Committee of the Red Cross (ICRC) is the custodian and promoter of IHL.

• Founded: 17 February 1863 (founding meeting in Geneva).
• Headquarters: Geneva, Switzerland.
• Legal status: Unique — a private Swiss association under the Swiss Civil Code, but with international legal personality recognised by states and the UN. Functions as a neutral, independent humanitarian organisation.
• Key roles:
  • Monitors compliance with the Geneva Conventions.
  • Visits prisoners of war and political detainees.
  • Delivers humanitarian aid in conflict zones.
  • Traces missing persons; reunites families.
  • Promotes IHL through training militaries and governments.
  • Has the sole right under the Geneva Conventions to use the Red Cross emblem.

The ICRC operates in over 100 countries, with over 20,000 staff worldwide.

War Crimes and ICC Jurisdiction

War crimes are serious violations of IHL — including wilful killing of civilians, torture of POWs, intentional attacks on hospitals, and use of prohibited weapons. They are subject to universal jurisdiction — any state may prosecute war criminals regardless of where the crime occurred.

The International Criminal Court (ICC), established by the Rome Statute (1998, effective 2002), has jurisdiction over:

• War crimes
• Crimes against humanity
• Genocide
• Crime of aggression

The ICC can prosecute individuals (not states) when national courts are unable or unwilling to prosecute. As of 2026, 124 states are party to the Rome Statute.

India is not a party to the Rome Statute and has not ratified it, citing concerns about ICC's jurisdiction over situations that India considers within domestic jurisdiction, and the potential for politically motivated referrals.

India and IHL

India's Ratification Status:

• India has ratified all four Geneva Conventions of 1949 — and is therefore bound by their core obligations, including Common Article 3.
• India has not ratified Additional Protocol I or Additional Protocol II to the Geneva Conventions.

Official position on AP I/II: In January 2019, the Minister of State for External Affairs stated in Parliament: "No decision has been taken to ratify the Additional Protocols I and II to the Geneva Conventions." India's objections historically related to AP I's provisions on national liberation movements — India argued that once such movements were classified as international conflicts under AP I, Protocol II for non-international conflicts would be redundant. There are also concerns about provisions on reservations and the definition of combatants.

Domestic legislation: India's Geneva Conventions Act, 1960 incorporates the four 1949 conventions into domestic law, making grave breaches of the conventions criminal offences under Indian law.

IHL vs. International Human Rights Law (IHRL)

Both frameworks protect persons — but they operate in different contexts and with different rules:

During armed conflict, both frameworks apply simultaneously — IHL as lex specialis (more specific law) governs the conduct of hostilities; IHRL continues to apply where consistent with IHL.

Recent Applications

Gaza Conflict (2023–2025)

The Gaza conflict raised fundamental IHL questions: lawfulness of blockades, proportionality of aerial bombardment in densely populated areas, protection of hospitals and medical personnel, use of civilian infrastructure by armed groups, and famine as a method of warfare. The ICJ's provisional measures order in January 2024 in South Africa v. Israel (Genocide Convention case), ICC arrest warrants against PM Netanyahu and Defence Minister Gallant (November 2024), the Gaza ceasefire (19 January 2025), and the ICJ Advisory Opinion on the OPT (22 October 2025) collectively represent the most significant IHL accountability developments in decades.

Russia-Ukraine War (2022–ongoing)

Allegations of war crimes include intentional attacks on civilian infrastructure (energy grids, hospitals), deportation of Ukrainian children, use of cluster munitions in populated areas, and torture of POWs. The ICC issued an arrest warrant against Russian President Vladimir Putin in March 2023 for the alleged unlawful deportation of Ukrainian children.

Recent Developments (2024–2026)

Gaza Conflict and IHL Violations Debate (2024–2026)

The Israel-Hamas conflict in Gaza (October 2023–January 2025) generated the most significant IHL debate in decades. Key milestones:

• ICJ Provisional Measures (January 2024): In South Africa v. Israel, the ICJ ordered Israel to take measures to prevent genocide under the Genocide Convention — the first such order in an ongoing conflict. The ICJ found it "plausible" that rights under the Genocide Convention were at risk.
• ICC Arrest Warrants (November 2024): The ICC issued arrest warrants for Israeli PM Benjamin Netanyahu and former Defence Minister Yoav Gallant for alleged war crimes and crimes against humanity in Gaza, and for Hamas commanders. First ICC warrant against a sitting leader of a US-allied democracy.
• Gaza Ceasefire (19 January 2025): A ceasefire entered into effect on 19 January 2025. However, South Africa confirmed the ICJ genocide case continues despite the ceasefire — Israel filed its counter-memorial on 12 March 2026.
• ICJ Advisory Opinion on Palestine Occupation (22 October 2025): The ICJ issued an advisory opinion on Israel's legal obligations in the Occupied Palestinian Territories (OPT) — covering the legality of the prolonged occupation, annexation, and settlements. The opinion, while non-binding, carries significant authority for international law.
• Belgium joined the case (December 2025): Belgium formally joined South Africa's ICJ genocide proceedings; Brazil, Colombia, Ireland, Mexico, Spain, and Turkey had also joined.

India abstained from several UN General Assembly resolutions calling for humanitarian ceasefires and calling on Israel to comply with ICJ orders, citing its traditional policy of not taking sides in conflicts where it is not directly involved, while providing humanitarian assistance (medicines, food) to Gaza through Jordan and the ICRC.

UPSC angle: Gaza — ICJ provisional measures (January 2024), ICC arrest warrants (November 2024), Gaza ceasefire (January 19, 2025), ICJ advisory opinion (October 22, 2025), India's abstentions and humanitarian aid. IHL principles tested: distinction, proportionality, precaution, humanitarian access (Common Article 3), collective punishment prohibition. The ICJ case South Africa v. Israel is one of the most significant international law cases in recent decades.

Ukraine-Russia War — IHL and War Crimes Documentation (2024)

The Russia-Ukraine war, entering its third year in 2024, continued to generate IHL violations documentation. The ICC issued an arrest warrant for President Putin in March 2023 for unlawful deportation of Ukrainian children — an ongoing situation with significance in 2024 as Russia continued operations. The UN Human Rights Monitoring Mission documented widespread violations by Russian forces including targeting of civilian infrastructure.

India maintained its consistent abstention on UN votes condemning Russian actions, defending its stance on the basis of strategic autonomy and the need for dialogue. PM Modi's July 2024 visit to Moscow and his subsequent August 2024 visit to Kyiv represented India's attempt at playing a potential mediator role. Modi's embrace of Putin coincided with Russian missile strikes on a Ukrainian children's hospital — drawing sharp criticism from Zelensky and EU leaders.

UPSC angle: India's abstention pattern at the UN on Ukraine resolutions is a recurring Mains question about India's foreign policy and its IHL obligations. The distinction between jus ad bellum (legality of Russia's invasion) and jus in bello (conduct of hostilities under IHL) is critical.

Operation Sindoor and IHL Principles — May 2025

India's Operation Sindoor (6–7 May 2025), targeting nine terrorist infrastructure sites in Pakistan and Pakistan-administered Kashmir, raised IHL questions about proportionality, distinction, and the use of force against non-state actors sheltered in another state's territory. India explicitly stated that only terrorist camps were targeted, not Pakistani military or civilian infrastructure — invoking the principle of distinction. The 23-minute operation's precision-strike character reflected an attempt to satisfy proportionality requirements.

Pakistan characterised the strikes as attacks on civilian areas. The episode is legally significant as India is not in a formal "armed conflict" with Pakistan under IHL, raising questions about whether international humanitarian law or international human rights law (IHRL) governs such cross-border counterterrorism operations.

UPSC angle: Operation Sindoor connects IHL principles (distinction, proportionality, military necessity) with India's counter-terrorism strategy. Expect a Mains question linking IHL, cross-border terrorism, and state responsibility.

Myanmar Military Operations and India's IHL Dilemma

The Myanmar civil war (post-February 2021 coup) continued to intensify through 2024, with the military junta facing a coordinated offensive from resistance forces. India suspended the Free Movement Regime (FMR) along the India-Myanmar border in February 2024 and announced plans to fence the 1,643 km border. India's Myanmar policy has to balance IHL concerns (against supporting a regime committing gross violations) with strategic interests (connectivity, anti-insurgency cooperation, countering Chinese influence).

UPSC angle: India-Myanmar-IHL nexus is important for GS-II. India's decision to engage with the junta despite documented atrocities is tested in questions about India's foreign policy principles vs. pragmatism.

PYQ Relevance

• IHL has appeared as a direct question in UPSC Law Optional (Paper I) — in 2014 and 2023. For GS2, IHL-related content is typically integrated into broader questions on India's foreign policy, humanitarian crises, or India's position on UN peacekeeping and conflict zones.
• Likely GS2 Mains angle: "Discuss the relevance of International Humanitarian Law in contemporary armed conflicts. What is India's position on IHL treaties?" (standard analysis-type question).
• Prelims: ICRC founding year, Geneva Conventions count, non-refoulement vs. Common Article 3, India's treaty ratification status.

Exam Strategy

Approach: Structure IHL answers around three levels: (1) Foundational treaties — what they protect and whom; (2) Core principles — distinction, proportionality, precaution; (3) Enforcement gap — why violations persist and what mechanisms exist.

Key numbers to memorise:

• ICRC founding: 1863 (February)
• Four Geneva Conventions: 12 August 1949
• Additional Protocols: 8 June 1977
• Universal ratification of GCs: 196 states
• India: Party to all 4 GCs; NOT a party to AP I, AP II, or the Rome Statute

Distinguish: IHL (law during conflict) vs. jus ad bellum (law on resort to force) vs. IHRL (human rights law). Many students conflate these.

Key Terms

Geneva Conventions

• Definition: The Geneva Conventions are four international treaties adopted on 12 August 1949 (with three later Additional Protocols) that form the core of international humanitarian law, setting binding rules to protect the wounded and sick, prisoners of war, and civilians during armed conflict.
• Context: Negotiated in Geneva under the auspices of the International Committee of the Red Cross (ICRC) in the aftermath of the Second World War, the 1949 Conventions revised and expanded earlier humanitarian treaties dating back to 1864. They entered into force on 21 October 1950 and have since achieved universal ratification by 196 states, making them among the most widely accepted treaties in the world. India ratified all four Conventions in 1950 and gave them domestic effect through the Geneva Conventions Act, 1960.
• UPSC Relevance: This is a foundational GS2 (International Relations) concept underpinning questions on international humanitarian law, the laws of war, and the role of the ICRC and the UN system. For Prelims, aspirants should know the subject of each of the four Conventions, the years of the Additional Protocols (1977 and 2005), the universal ratification figure, and that India has ratified the four Conventions but not Additional Protocols I and II. For Mains, it links to debates on protection of civilians and prisoners of war, India's stance on internal armed conflicts, and the gap between IHL norms and contemporary warfare. No direct PYQ is cited here; it remains a high-utility background concept for IR and ethics-in-war discussions.
