First published in 1970, Akehurst’s Modern Introduction to International Law rapidly established itself as a widely used and successful textbook in its field. Being the shortest of all the major textbooks in this area, it continues to offer a concise and accessible overview of the concepts, themes, and issues central to the growing system of international law, while retaining Akehurst’s original positivist approach that accounts for the essence and character of this system of law. This new tenth edition has been further revised and updated by Alexander Orakhelashvili to take account of multiple latest developments in the field, accounting for over forty-five decisions of international and national courts, as well as a number of treaties and major incidents that have occurred since the ninth edition of this textbook was published. Based on transparent positivist methodology and with a distinctive cross-jurisdictional approach which opens up the discipline to students from all backgrounds, this engaging, well-structured, and reputable textbook will provide students with all the tools, methods, and concepts they need to fully understand this complex and diverse subject. It is an essential text for all undergraduate and postgraduate students of international law, government and politics, and international relations.
