Phase IFoundation

Background

Overview

UPSC frequently tests knowledge of international law, human rights, and the legal frameworks governing armed conflicts (GS2). Understanding IHL is crucial for analyzing global conflicts and India's foreign policy stance.

International Humanitarian Law (IHL), also known as the laws of armed conflict, is a set of rules that seek to limit the effects of armed conflict for humanitarian reasons. It protects persons who are not or are no longer participating in hostilities and restricts the means and methods of warfare. War crimes, crimes against humanity, and genocide are grave breaches of IHL and international criminal law.
