International Humanitarian Law (IHL), often referred to as the law of armed conflict, constitutes a fundamental branch of public international law aimed at regulating the conduct of hostilities and mitigating the humanitarian consequences of war. Rooted in principles of humanity, necessity, proportionality, and distinction, IHL seeks to strike a delicate balance between military objectives and the protection of individuals who are not, or are no longer, participating in hostilities. The contemporary relevance of IHL has increased significantly due to the evolving nature of armed conflicts, which are increasingly characterised by non-state actors, technological advancements, and complex geopolitical dynamics.
The historical evolution of IHL reflects a gradual transition from customary humanitarian practices to codified legal norms. Early manifestations of humanitarian restraint can be traced to ancient civilizations, including Indian, Islamic, and European traditions, which imposed ethical limitations on warfare. However, the modern legal framework of IHL began with the adoption of the Geneva Convention of 1864, inspired by the humanitarian efforts of Henry Dunant following the Battle of Solferino. This marked the beginning of treaty-based regulation of armed conflict, focusing initially on the protection of wounded soldiers and medical personnel.
Subsequent developments, particularly the Hague Conventions of 1899 and 1907, complemented the Geneva framework by regulating the means and methods of warfare. Together, these legal traditions formed the dual pillars of IHL—protection of victims and regulation of hostilities. The atrocities of the Second World War exposed significant gaps in existing legal protections, leading to the adoption of the four Geneva Conventions of 1949, which expanded the scope of protection to include civilians and prisoners of war. The Additional Protocols of 1977 further strengthened these protections and extended the applicability of IHL to non-international armed conflicts, reflecting the changing nature of warfare.
