How did the aftermath of ww1 lead to Mussolini’s rise?

Wounded while serving with the bersaglieri (a corps of sharpshooters), he returned home a convinced antisocialist and a man with a sense of destiny. As early as February 1918, he advocated the emergence of a dictator— “a man who is ruthless and energetic enough to make a clean sweep”—to confront the economic and political crisis then gripping Italy. Three months later, in a widely reported speech in Bologna, he hinted that he himself might prove to be such a man. The following year the nucleus of a party prepared to support his ambitious idea was formed in Milan. In an office in Piazza San Sepolcro, about 200 assorted republicans, anarchists, syndicalists, discontented socialists, restless revolutionaries, and discharged soldiers met to discuss the establishment of a new force in Italian politics. Mussolini called this force the fasci di combattimento (“fighting bands”), groups of fighters bound together by ties as close as those that secured the fasces of the lictors—the symbols of ancient Roman authority. So fascism was created and its symbol devised.  

At rallies—surrounded by supporters wearing black shirts—Mussolini caught the imagination of the crowds. His physique was impressive, and his style of oratory, staccato and repetitive, was superb. His attitudes were highly theatrical, his opinions were contradictory, his facts were often wrong, and his attacks were frequently malicious and misdirected; but his words were so dramatic, his metaphors so apt and striking, his vigorous, repetitive gestures so extraordinarily effective, that he rarely failed to impose his mood.
