This engaging text introduces readers to the sociology of cults. Covering the history and current state of cult studies, this book includes topics ranging from doomsday cults and new religious movements through to self-help cults, the cult of celebrity, intellectuals, and entrepreneurs. Case studies as varied as David Koresh and the Branch Davidians, the Manson family, and the cult brands of Elon Musk, Andrew Tate and Jordan Peterson are deployed to shed new light on cult formation in the twenty-first century.Amidst the rise of populist demagogues, the online radicalisation of alienated individuals, and the proliferation of celebrities and gurus with avid followings, cult dynamics are everywhere in society. Yet key urgent questions have not been clearly and concisely addressed: What are cults? Why do they emerge? How are they established and maintained? What is the future of cults, and why are we so fascinated by them? This book explores these questions by tracing the spectrum of cult formation historically and in today’s networked media ecosystem.This accessible introduction to the darkly fascinating world of cults is essential reading for academics and students of sociology, social psychology, religion, politics, business and cultural studies, and anyone interested in understanding the relationship between cults and society.
