How laws are created, shaped, and applied is a significant but often overlooked component of studies on armed conflict. Almost every contentious legal question involves aspects of law-making and shaping, be it the determination of a rule's scope of application, whether and how to regulate a “new” situation, or determining which sources and materials to take into account. As such, all who operate in this space - whether academic, practitioner, policy-maker, or legal advisor - must appreciate and understand the forces, factors, and actors which converge to make and shape the ever-developing law of armed conflict.

This volume brings together several key contributors to explore this making and shaping in depth. A variety of aspects of law-making and shaping are analyzed, from the methodology behind identifying principles and rules of law, to what weight should be given to the views of particular actors, to the various forums where the law is made and shaped. It examines foundational materials of the law of armed conflict including the 1949 Geneva Conventions and considers the influence of a wide scope of actors, ranging from States, the International Committee of the Red Cross, and international courts and tribunals through to expert groups, commissions of inquiry, and non-state armed groups. This volume also asks us to broaden our gaze beyond spaces where the law is traditionally created to uncover different types of making and unmaking
