International humanitarian law (IHL) plays a crucial role in conflicts by establishing legal standards that protect individuals not participating in hostilities, such as civilians, medical personnel, and aid workers. IHL seeks to limit the effects of armed conflict by regulating the means and methods of warfare, promoting principles like distinction, proportionality, and necessity. Compliance with IHL is essential for humanitarian access and the protection of human rights during conflict, contributing to a more civilized approach to warfare and accountability for violations.
