This Oxford Handbook examines the sources of international law, how the understanding of sources changed throughout the history of international law; how the main legal theories understood sources; the relationship between sources and the legitimacy of international law; and how sources differ across the various sub-areas of international law.

Because of its unique nature, the sources of international law are not always easy to identify and interpret. This book provides an ideal introduction to these sources for anyone needing to better understand where international law comes from. As well as looking at treaties and custom, the book will look at more modern and controversial sources.

The Oxford Handbook of the History of International Law provides an authoritative and original overview of the origins, concepts, and core issues of international law. The first comprehensive Handbook on the history of international law, it is a truly unique contribution to the literature of international law and relations. Pursuing both a global and an interdisciplinary approach, the Handbook brings together some sixty eminent scholars of international law, legal history, and global history from all parts of the world. Covering international legal developments from the 15th century until the end of World War II, the Handbook consists of over sixty individual chapters which are arranged in six parts. The book opens with an analysis of the principal actors in the history of international law, namely states, peoples and nations, international organisations and courts, and civil society actors. Part Two is devoted to a number of key themes of the history of international law, such as peace and war, the sovereignty of states, hegemony, religion, and the protection of the individual person. Part Three addresses the history of international law in the different regions of the world (Africa and Arabia, Asia, the Americas and the Caribbean, Europe), as well as 'encounters' between non-European legal cultures (like those of China, Japan, and India) and Europe which had a lasting impact on the body of international law. Part Four examines certain forms of 'interaction or imposition' in international law, such as diplomacy (as an example of interaction) or colonization and domination (as an example of imposition of law). The classical juxtaposition of the civilized and the uncivilized is also critically studied. Part Five is concerned with problems of the method and theory of history writing in international law, for instance the periodisation of international law, or Eurocentrism in the traditional historiography of international law. The Handbook concludes with a Part Six, entitled "People in Portrait", which explores the life and work of twenty prominent scholars and thinkers of international law, ranging from Muhammad al-Shaybani to Sir Hersch Lauterpacht. The Handbook will be an invaluable resource for students and scholars of international law. It provides historians with new perspectives on international law, and increases the historical and cultural awareness of scholars of international law. It is the standard reference work for the global history of international law.

This Oxford Handbook examines the sources of international law, how the understanding of sources changed throughout the history of international law; how the main legal theories understood sources; the relationship between sources and the legitimacy of international law; and how sources differ across the various sub-areas of international law.

This volume examines the role of League of Nations committees, particularly the Advisory Committee of Jurists (ACJ) in shaping the statute of the Permanent Court of International Justice (PCIJ). The authors explore the contributions of individual jurists and unofficial members in shaping the League’s international legal machinery. It is a companion book to The League of Nations and the Development of International Law: A New Intellectual History of the Advisory Committee of Jurists (Routledge, 2021). One of the guiding principles of the book is that the development of international law was a project of politics where the idea and notion of an international society must contend with the political visions of each state represented on the different legal committees in the League of Nations during the drafting of the Covenant. The book constitutes a major contribution to the literature in that it shows the inner workings of some of the legal committees of the League and how the political role of unofficial members was influential for the development of international law in the early twentieth century and how they influenced the political and legal process of the ACJ. The book will be an essential reference for those working in the areas of International Law, Legal History, International Relations, Political History, and European History.

The Oxford Handbook of International Legal Theory provides an accessible and authoritative guide to the major thinkers, concepts, approaches, and debates that have shaped contemporary international legal theory. The Handbook features 48 original essays by leading international scholars from a wide range of traditions, nationalities, and perspectives, reflecting the richness and diversity of this dynamic field. The collection explores key questions and debates in international legal theory, offers new intellectual histories for the discipline, and provides fresh interpretations of significant historical figures, texts, and theoretical approaches. It provides a much-needed map of the field of international legal theory, and a guide to the main themes and debates that have driven theoretical work in international law. The Handbook will be an indispensable reference work for students, scholars, and practitioners seeking to gain an overview of current theoretical debates about the nature, function, foundations, and future role of international law.
