'Professor Sassoli has combined his first hand experience of the challenges facing the application of international humanitarian law with his scholarly understanding of international law. He sets out the details necessary for a complete understanding of humanitarian law but also highlights the contemporary controversies. One of the many qualities of this book is that the author always offers us his considered view on what are the best solutions to the dilemmas he highlights. This book is destined to become an authoritative point of reference for generations to come.' - Andrew Clapham, Graduate Institute of International and Development Studies, Switzerland International humanitarian law (IHL) protects persons and property affected by armed conflicts. Focusing on the controversies that impact IHL in practice, this much-anticipated book from leading expert Marco Sassoli discusses when IHL applies, its substantive rules, how to ensure its respect and whether the traditional distinction between international and non-international armed conflicts remains relevant. Sassoli draws on a depth of practical experience to provide invaluable insight and comprehensive guidance on the rules protecting certain categories of persons (for example, civilians, wounded, etc.) during conflict and the rules governing different types of conduct (or example, occupation, naval warfare, etc.). The book examines how these rules interact with other branches of international law, such as human rights and international criminal law, and how the rules are applied to non-State armed groups. Cross-cutting issues, including terrorism, autonomous weapons, cyber warfare, gender and cultural heritage, are also addressed, providing readers with a well-rounded view of IHL and associated concerns. Structured in a clear and accessible way, this book will be the turn-to resource for scholars, lawyers, civil servants and other actors directly involved in the sphere of IHL. It will also be the essential text for forthcoming generations of students, giving them a solid understanding of both the rules relating to IHL and how they are implemented in practice.

The four Geneva Conventions, adopted in 1949, remain the fundamental basis of contemporary international humanitarian law. They protect the wounded and sick on the battlefield, those wounded, sick or shipwrecked at sea, prisoners of war, and civilians in time of war. However, since they were adopted warfare has changed considerably. In this groundbreaking commentary over sixty international law experts investigate the application of the Geneva Conventions and explain how they should be interpreted today. It places the Conventions in the light of the developing obligations imposed by international law on states, armed groups, and individuals, most notably through international human rights law and international criminal law. The context in which the Conventions are to be applied and interpreted has changed considerably since they were first written. The borderline between international and non-international armed conflicts is not as clear-cut as was once thought, and is complicated further by the use of armed force mandated by the United Nations and the complex mixed and transnational nature of certain non-international armed conflicts. The influence of other developing branches of international law, such as human rights law and refugee law has been considerable. The development of international criminal law has breathed new life into multiple provisions of the Geneva Conventions. This commentary adopts a thematic approach to provide detailed analysis of each key issue dealt with by the Conventions, taking into account both judicial decisions and state practice. Cross-cutting chapters on issues such as transnational conflicts and the geographical scope of the Conventions also give readers a full understanding of the meaning of the Geneva Conventions in their contemporary context. Prepared under the auspices of the Geneva Academy of International Humanitarian Law and Human Rights, this commentary on four of the most important treaties in international law is unmissable for anyone working in or studying situations of armed conflicts.
