27. The Law of Armed Conflict (International Humanitarian Law)

The international law of armed conflict (also known as international humanitarian law or the law of war) regulates the conduct of hostilities—including the use of weaponry—and the protection of victims in situations of both international and non-international armed conflict. Rooted in customary law, often of very great antiquity, since the late nineteenth century it has become one of the most intensively codified areas of international law. This chapter outlines the scope of application of the law; issues of personal status (combatants and civilians); the conduct of hostilities (methods and means of warfare, including choice of weapons and targeting operations); the protection of victims (sick, wounded, shipwrecked, prisoners of war, and civilians); and various ways of securing the law’s implementation and enforcement.
