Conspiracies are everywhere. They are the lifeblood of politics, business and our daily lives. This truly international and all-embracing encyclopedia explains the details of the world's major popular conspiracies, listing them chronologically under subject matter and cross-referencing them continually (because so many conspiracy theories interact on some level).

Conspiracies are often international in their sweep and their impact. The brutal stabbing of Julius Caesar (the conspiracy which has defined political assassinations ever since) plunged the Roman Empire into civil war, which then engulfed much of the known western world. More recently the Cambridge spies (Philby, Blunt, MacLean and Burgess) helped Russia throughout WWII and then re-defined the Cold War afterwards, Philby's defection casting a 30-year shadow over CIA/Anglo-American relations.

Though conspiracies define our everyday lives, there is no body of serious academic research to understand their role, nature or defining characteristics. Most historians prefer to adhere to the cock-up theory of history, in which everything happens by accident or incompetence. Although this view is favoured by academics and historians, it is rejected by a large part of the general public who prefer the evidence of their own lives. However they consume their media, what they see is a mesh of conspiracies that define the texture of their everyday lives, often for the worst. Most people believe that there is a grain of truth in most theories about conspiracies. This book is for them.
