Background

Overview

Understanding the legal framework governing armed conflicts is essential for analyzing international relations, human rights issues, and the responsibilities of states and non-state actors in 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.
