This book provides a fascinating account of the historical origin of conspiracy-minded tales of the Illuminati. If you've read Dan Brown's novel Angels and Demons or come across any websites warning about the coming New World Order, you might be forgiven for thinking that these conspiracy rumours are grounded in solid historical fact (as Brown asserts) or have only recently been discovered. But Porter shows how, over the last couple of centuries, many parts of the Illuminati legend were invented by a series of dodgy characters that included aristocratic Nazi sympathisers and rabid anticommunists. Even more damning, important elements of the myth were part of an elaborate spoof written by pranksters of the 1960s (also the case with elements of The Da Vinci Code). What's important about this book is that it shows how conspiracy theories about the Illuminati often reveal more about the people who believe in them than about the supposed hidden sources of power. Porter's book is well written, sorting the wheat from the chaff in the historical record, as well as offering user-friendly guides to the political context in which each episode of fear-mongering emerged.
