This book is a systematic inquiry of conspiracy theories across Latin America. Conspiracy theories project not only an interpretive logic of reality that leads people to believe in sinister machinations, but also imply a theory of power that requires mobilizing and taking action. Through history, many have fallen for the allure of conspiratorial narratives, even the most unsubstantiated and bizarre. This book traces the main conspiracy theories developing in Latin America since late colonial times and into the present, and identifies the geopolitical, socioeconomic and cultural scenarios of their diffusion and mobilization. Students and scholars of Latin American history and politics, as well as comparatists, will find in this book penetrating analyses of major conspiratorial designs in this multi-state region of the Americas.
