"Mussolini was, of course, not the only dissident ever to leave a socialist party, especially during the trauma of the First World War. In many countries, the great conflict demanded that a choice be made between the ideals of internationalist socialism and those of the nation."

“On 4 July before an audience at the ‘new town’ of Aprilia, excoriated what he rudely called ‘the great demoplutocracies’; they were, he added flatly, the ‘enemies of Italy’. The new tone of exasperation in his words worried members of the Italian establishment, but Mussolini, taking his temerity one step further, now told Ciano that the ‘defeatist’ bourgeoisie needed to be brought into line by a ‘third wave’ of Fascism.”

“Other, mostly richer Italians dealt with the meaning of life under the dictatorship in a more straightforward manner. What might be termed their everyday Mussolinism was, however, scarcely based on a literal application of Fascist totalitarianism. When their actions are reviewed carefully, it becomes plain that they by no means reliably believed, obeyed or fought, despite the regime slogan–credere, obbedire, combattere–insisting that they should.”

“In this conflict , Mussolini for the moment stood on the other side of the barricades; on 10 June, destined to be a redolent date in Fascist history, he urged: ‘We must take up again our anti-militarist propaganda to ensure that bayonets are only raised when we want them to be… Our propaganda must break into the barracks, where currently the sons of the people are taught how to kill their own brothers.’”

“As Archduke Franz Ferdinand made his way to Sarjevo, Mussolini remained an extreme socialist, committed to pulling down the Liberal order in the interests of world-spanning revolution. The outbreak of the war did not at first alter that situation. However, by September 1914, the attachment of the editor of Avanti! to the official line of neutralism was crumbling. In October, Mussolini broke from the party, proclaiming that, although still a believing socialist, he was certain that the cause of social overturn could be better hurried by war than by Italy remaining at peace. Mussolini thus joined the ranks of the interventionists, a motley crew in terms of political background, although the great majority nourished a deep belief in their intellectuality and self-importance.”

“At the next socialist party congress, held in July 1912 at Reggio Emilia, the PSI again split, the most vehement attacks on the three moderates coming from the young ‘maximalist’ or radical, Benito Mussolini, who soon took over the editorship of the party’s paper Avanti! from Claudio Treves, another reformist, and, later, for good measure, fought a duel against him.”

“If ever a word was in the air, then in Italy around the time of the First World War, it was ‘Fascist.’ Fascista, Fascismo, Fascio: each turned up on numerous occasions and in diverse settings. Doctor deputies, endeavouring to be a pressure group, formed themselves into a Fascio Medico Parlamentare as early as 1906.”
