Phase IFoundation

Background

Overview

Understanding international legal frameworks, especially those governing conflict and human rights, is crucial for UPSC. It relates to international justice, accountability, and the rule of law in global affairs.

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.
