The Geneva Conventions of 1949 form the foundation of international humanitarian law. Four distinct treaties, adopted after World War II, each cover a category of protected persons. Measuring their actual scope requires comparing what each convention protects, the obligations it imposes, and the limits that contemporary practice reveals.
Four conventions, four fields of protection: comparative table
Each convention targets a specific category of war victims. The table below summarizes their respective scopes.
| Convention | Protected Persons | Central Obligation |
|---|---|---|
| Convention I | Wounded and sick members of armed forces in the field | To collect and care for without discrimination |
| Convention II | Wounded, sick, and shipwrecked members of armed forces at sea | To protect hospital ships and medical personnel |
| Convention III | Prisoners of war | To ensure humane treatment, allow visits from the ICRC |
| Convention IV | Civilians in time of war | To prohibit deportations, hostage-taking, and degrading treatment |
The common point among the four texts is the common Article 3, applicable to non-international conflicts. It imposes a minimum humanitarian standard even in civil wars, where other provisions generally apply only to conflicts between states.
To delve deeper into the precise content of each of these treaties, the Geneva Conventions of 1949 detail the obligations article by article.
ICRC Comments in 2025: What Changes in Interpretation
A treaty from 1949 is not read the same way on the day after its adoption and several decades later. Since 2025, the ICRC has been publishing new comments article by article on the Fourth Convention (protection of civilians), incorporating the practice of contemporary conflicts.
Duty of Prevention and Responsibility of Third States
The 2025 comments on Article 1 (“to respect and ensure respect”) significantly broaden the scope of this clause. The ICRC emphasizes the duty to prevent violations, not just to repress them.
This point directly concerns states that provide weapons, intelligence, or operational support to a belligerent. According to the updated reading, a third state that continues to supply military equipment to a party in the conflict while knowing that it violates the conventions engages its own responsibility under humanitarian law.
Obligations of Non-State Armed Groups
The 2025 comment on common Article 3 specifies that non-state armed groups are directly bound by minimum humanitarian rules. This reading goes beyond the traditional framework of treaty law, which generally binds only the signing states. It reflects the evolution of contemporary conflicts, where the majority of wars involve at least one non-state actor.
Access to Prisoners of War: A Concrete Indicator of Implementation
Convention III provides that the ICRC may visit prisoners of war to verify their conditions of detention. This mechanism is one of the few control tools provided by the texts.
In practice, this access remains precarious. According to Reuters (September 2026), the ICRC reports having had no access to Ukrainian prisoners of war for two years. This situation illustrates the gap between written law and its effective application.
- Convention III requires that ICRC visits be authorized without restriction, including interviews without witnesses with detainees.
- The refusal of access constitutes a direct violation of the convention, but no binding mechanism exists to compel a state to open its detention facilities.
- The ICRC can only publicly express its concerns, which it does rarely, preferring confidential diplomacy to preserve its future action possibilities.
Common Article 3 and Contemporary Conflicts: The Minimum Humanitarian Standard in Question
Common Article 3 is the most cited provision of the Geneva Conventions because it applies to all armed conflicts, including those that are not international. It prohibits attacks on life, torture, humiliating treatment, and convictions without regular trial.
Its strength lies in its simplicity: a few lines suffice to establish a threshold below which no belligerent party can descend. However, this same conciseness leaves gray areas regarding the qualification of a conflict. Does a confrontation between government forces and an armed group reach the threshold of a “non-international armed conflict”? The answer conditions the applicability of Article 3, and the parties involved often contest this qualification to evade their obligations.
The 2025 ICRC comments attempt to clarify these thresholds, relying on the jurisprudence of international criminal tribunals and the practice accumulated since the 1990s. The criterion adopted is that of the intensity of violence and the degree of organization of the armed group, regardless of the political recognition of the conflict by the parties.
The Geneva Conventions impose obligations that come into effect as soon as the factual threshold is reached. The difficulty has remained the same since 1949: enforcing these rules when no superior authority has the power to compel compliance.
The updated ICRC comments do not resolve this structural problem, but they tighten the interpretation criteria and document the obligations with a precision that makes it more difficult for a state or armed group to plead ignorance.
