The rise of fascism in Italy is a subject of interest to anarchists as Mussolini's rise cannot be detached from the biennio rosso, the two red years of 1919 and 1920. Unfortunately, there are few decent books on this period in English.
This made Tom Behan's "The Resistible Rise of Benito Mussolini" potentially very important. It claims to be the about the "Arditi del Popolo" (AdP), the world's first anti-fascist movement . The actual accounts of the development of the AdP and specific (successful) fights against the Black Shirts in Rome, Parma and Sarzana presents the English speaking
world with much new material. However the book is riddled with inaccuracies and downright distortions which are easily identified simply by reading the references Behan himself provide
The history of the anarchist resistance to fascism is something we
are never told about in mainstream or even left histories. The
victors over fascism wrote the 'history' of anti-fascism after
W.W.II.
