This book gives a quite detailed insight on the tools and tasks of propaganda in European and /or Western history. Starting with ancient times the author goes up till the Gulf War and the meaning of propaganda today. In all those different eras propaganda was transporting similar messages, even when technical possibilities had not been fairly as widespread as today. Taylor's book is leading the reader through those different periods, trying to show the typical elements of each one.
