The 4th part of my video documentary on dictatorship is up on YouTube. This video series is to support my latest book The Terrible Beauty of Dictatorship. In this part the roots of left-wing and conservative dictatorships is presented. Two figures are critical; Donoso Cortes, the Spanish architect of conservative dictatorship and Joseph Weydemeyer, who coined the term dictatorship of the proletariat. Click on the link below to view.
