Praise of previous edition:'Comprehensive and conceptually sophisticated, this history does more than recount the events of the past century, it explains them lucidly and engages the reader in crucial questions. There is no better guide to where we are and how we got there. I wish I had been assigned a book as good as this when I was a student.'Robert Jervis, Adlai E. Stevenson Professor of International Politics, Columbia University, USA'From the underlying causes of World War I to those behind the present decline of American influence, this third edition of a recognized classic provides a thoughtful, coherent, challenging, up-to-date and increasingly comprehensive account of the international history of the twentieth century and the opening decades of the present one. Caveat emptor: readers who dip in to learn something specific about one of the many conflicts and relationships it covers will inevitably be drawn into reading the entire chapter, if not the book.'Ned Lebow, Professor of International Political Theory, King’s College London, UK'This book is an impressive work of historical synthesis: it is comprehensive, sophisticated, and accessible. Students of History, International Relations, and Political Science should have it in their basic library, while non-academic readers will benefit from its overview of the revolutionary century that has passed, as a prelude to living in the revolutionary decades ahead. Highly recommended.'Ken Booth FBA, President of the David Davies Memorial Institute of International Affairs, and Senior Research Associate, Department of International Politics, Aberystwyth University, UK‘Students love this textbook on the International history of the Twentieth Century, so do their teachers. This third edition is most welcome. We enjoy a main story vividly and clearly told in chapters that also live their own independent lives. The historiographical surveys are marvels of clarity and compactness, and the questions that are addressed to the literature provide excellent pathways to further reading and classroom discussions. For this third edition the authors have succeeded admirably in bringing the book into the second decade of the 21st century. I am particularly pleased with the chapter on human rights, a topic for far too long neglected by most historians of international relations.’Helge Pharo, Professor of International History, University of Oslo, Norway
