Background

Overview

UPSC frequently examines international laws, conventions, and their violations in the context of global conflicts and humanitarian crises. Understanding IHL is crucial for analyzing state conduct, accountability, and the ethical dimensions of warfare.

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, aiming to strike a balance between military necessity and humanitarian considerations.
