In this episode, it is a particular pleasure to feature a conversation with Dr. Barry Buzan, an Emeritus Professor of International Relations at the London School of Economics and a honorary professor at the University of Copenhagen and Jilin University. Until 2012 he was Montague Burton Professor of International Relations at the LSE. Professor Buzan’s work has been foundational in the development of several research programs within International Relations theory and global history, most prolifically in the study of security and social structures of world politics through the methodological lenses of the Copenhagen and English Schools of IR, respectively. His scholarly profile stands out for the sheer number of individual as well as collaborative contributions he has made in these areas. The list of important published articles and books of his is simply too lengthy to recite here; but among his most influential works include: People, States, and Fear (published in 1983 and revised in 1991), The Logic of Anarchy with Charles Jones and Richard Little (1993), International Systems in World History: Remaking the Study of International Relations with Richard Little (2000), Regions and Powers: The Structure of International Security with Ole Waever (2003), From International to World Society? English School Theory and the Social Structure of Globalisation (2004), The Evolution of International Security Studies with Lene Hansen (2009), The Global Transformation: History, Modernity and the Making of International Relations with George Lawson (2015), and Re-Imagining International Relations: World Orders in the Thought and Practice of Indian, Chinese, and Islamic Civilizations with Amitav Acharya (2021). He is also the co-author of The Mind Map Book, with his brother, the late Tony Buzan. His latest book, and the subject of this conversation with him, is titled Making Global Society: A Study of Humankind Across Three Eras, published in 2023 in the Cambridge Studies in International Relations Series.
