Three millennia of secret services of the world. Rowen R.U.

American researcher Richard Wilmer Rowen devoted his work to the history of the special services, covering three millennia of the work of secret agents of different countries. The author explores the practice and evolution of surveillance from the Royal ones to be finished to a two -dealing association, from autocratic conspiracies and intrigues to state forms of the Black Stairs. Being not only a weapon of tyranny and protection of governments and armies, but also an underground method of international struggle, secret services used police surveillance and secret emissaries both in the Byzantine Empire and in medieval Asia. And under Napoleon, and up to the Entente and modernity, erecting a political conjugation from crafts to art.
