International humanitarian law is the law that governs the conduct of participants during armed conflict. This branch of law aims to regulate the means and methods of warfare as well as to provide protections to those who do not, or who no longer, take part in the hostilities. It is one of the oldest branches of international law and one of enduring relevance today. The Oxford Guide to International Humanitarian Law provides a practical yet sophisticated overview of this important area of law. Written by a stellar line up of contributors, drawn from those who not only have extensive practical experience but who are also regarded as leading scholars of the subject, the text offers a comprehensive and authoritative exposition of the field. The Guide provides professionals and advanced students with information and analysis of sufficient depth to enable them to perform their tasks with understanding and confidence. Each chapter illuminates how the law applies in practice, but does not shy away from the important conceptual issues that underpin how the law has developed. It will serve as a first port of call and a regular reference work for those interested in international humanitarian law.
