Secret Societies of the Middle Ages : The Assassins, the Templars, and the Secret Tribunals of Westphalia

This book explores the foundations of modern secret societies, examining the history and known facts of three very different organisations: the Assassins of the Middle East, the Templars of Europe, and the Secret Tribunals of Westphalia.

This was the first book to gather information on these secret orders and, although this is a reprint of an 1846 edition, it is still used widely as a reference book on the subject.
