One of the most important historical investigations carried out by Rai, signed by the great Sergio Zavoli with the collaboration of Luciano Onder and Edek Osser and the scientific consultancy of Alberto Aquarone, Gaetano Arfé, Renzo De Felice, Gabriele De Rosa, Gastone Manacorda and Salvatore Valitutti. The six-part series, broadcast for the first time in the autumn of 1972, represented, half a century after the "March on Rome", a significant assessment of the years of the advent of the Mussolini regime, recalled with the rigor of the best television journalism (Saint-Vincent Award 1973) and through the direct testimonies of over fifty protagonists of the time, both fascists and anti-fascists.
