“Overseen by a new editorial team, with new and updated chapters, the sixth edition of Theories of Inteational Relations provides a refreshing and dynamic insight into the state of the discipline at the start of the 2020s. Chapters offer a rich – yet systematic – discussion of core theories in Inteational Relations, and readers are invited to consider how these theories help us make sense of, and respond to, our contemporary global challenges:making Theories of Inteational Relations an indispensable resource for students and researchers alike.” ―Laura McLeod, Senior Lecturer in Inteational Politics, University of Manchester, UK
“This book not only provides excellent coverage of a wide range of theoretical approaches in Inteational Relations, but its introduction situates them in a critical historical dialogue that should be instructive for students and teachers alike. The line-up of contributors is stellar, and the treatment of approaches is nuanced and very much up to date.” ―Luis Cabrera, Associate Professor of Political Science, Griffith University, Australia
“This textbook continues to be core reading for students of Inteational Relations. The inclusion of chapters on postcolonialism and institutionalism make important contributions to the scope of this key text. A fantastic next step for this book.” ―Samantha Cooke, Senior Lecturer in Inteational Relations and Inteational Politics, Liverpool John Moores University, UK

Uniquely, this text in its sixth edition offers a more global introduction to IR which showcases insights from across the world, and by employing an historical sociology perspective throughout, shows how any understanding of IR is historically- and geographically-contingent. Also new for this edition are chapters on postcolonialism and institutionalism, as well as chapters to better make sense of the discipline and the dynamics within and between theories. Boxed cases now feature in every chapter, to apply theory to contemporary empirical examples from gendered policy in the UN to ‘fake news’, from migration to the Amazon’s forest fires.

This text remains the definitive companion for all students of Inteational Relations, at undergraduate and postgraduate levels.
