In 1898, Gustave LeBon published The Crowd, in which he examined the underlying forces behind the many horrors of the French revolution. More than 100 years later, its premises may be traced to the rise of Hitler, Mussolini, Pol Pot, Mao Tse-Tung, and countless American and European leaders. Here is presented an expansion and update of his work, in the hopes that the mistakes of the past are not repeated. Within is a step-by-step manual for the acquisition of political power, as well as the defense against those who would use the knowledge for their own purposes.
