The Encyclopedia of Revolutions and Revolutionaries — From Anarchism to Zhou Enlai by Martin van Creveld is an essential reference book for those interested in researching the history of revolutions and revolutionaries. The main drawback is the liberal, left-of-center academic bias that one has come to expect in most of these types of books.

Let us now discuss the more arcane, extreme and revolutionary, right-wing philosophy, namely anarchism. You may ask when and where in recent history have anarchist revolutionaries been successful?  For the answer, we must travel back in time to Spain during the Spanish Civil War (1936-39). It was in Barcelona and surrounding districts that idealist anarchism flourished in the early period of the war as anarchists defended the radical Republican government that the communists also supported against the military insurrection of General Francisco Franco.
