In a broad historical survey from the 'Family of Civilised Nations', through the Great Powers' club, to the G7 and G20 today, Naylor investigates the politics of membership in the exclusive clubs that manage international society and ensure its survival, providing us with a new way to think about how status competition has changed over time and what this means for international politics today. With its sociologically grounded theory, this book advances English School scholarship and transforms the study of contemporary summitry, providing a ground-breaking approach rooted in archival research, elite interviews, and ethnographic participant observation.
