"With their outstanding book, Krisch, Yildiz, and Martinez advance a welcome novel approach to slow dynamics of change in international law. As an alternative to doctrinal approaches, the book's framework brings encompassing interdisciplinary research experience with globally leading scholars in the field to bear and, as such is apt to account for 'a dynamism of small steps, of gradual change'. Students from International Law and International Relations as well as practitioners will be grateful for this oevre's most welcome attention to detail to gradual institutional change along carefully selected paths. A true masterpiece!" -- Antje Wiener, Professor of Political Science and Global Governance, University of Hamburg"Inter-disciplinarity is often preached, but rarely properly practiced. In this pathbreaking work, based on in-depth command of legal doctrine, Krisch, Yildiz and Martinez Esponda show how the political process of changing international law is embedded in legal rules while giving rise to new rules. A must-read for scholars of international law and international relations alike." -- Jan Klabbers, Whewell Professor of International Law, University of Cambridge"You will not necessarily agree with all that you will read in this rich volume. But beyond doubt, you will not only learn a great deal from it but become wiser.

In my book, this is the highest form of praise of scholarship." -- J.H.H. Weiler, Joseph Straus Professor of Law, New York University School of Law"Change in International Law is an essential read in the current period of disruption and change in international law and politics. The book couples theoretical advances with empirical analyses that are drawn from 25 episodes of international norm change covering eight domains of international law. The findings challenge some widely held understandings in international legal studies. Change in International Law builds skillfully on insights from both legal and political analysis and will be an indispensable resource for students, scholars, and practitioners.
