Bringing together the most influential scholars in the field, the fifth edition of this best-selling text provides unrivalled coverage of international relations theories and arguments. Dunne, Kurki and Smith explore the full spectrum of theoretical perspectives and debates, ranging from the historically dominant traditions of realism, liberalism and Marxism to traditionally marginalised postcolonialism and green theory. The fifth edition features a new chapter on global IR, encouraging students to critically reflect on the context of the field's development and appreciate the importance of viewing international relations theories from truly representative perspectives. Each chapter is dedicated to a particular theory and features a case study that bridges theory and practice by showing how theory can be used to explain real world political dilemmas, whilst accompanying case study questions encourage analytical thinking and help readers understand the value of applying theory to concrete political problems. Spotlights on key books and articles encourage readers to go beyond the textbook and develop their research interests, exploring important works in the field.
