After being arrested several times and travelling throughout Italy, Bianchi became editor of La Scintilla in 1910; he launched the idea that PSI and syndicalists should reunite on electoral lists for the expected administrative elections.

However, Bianchi was forced by the tight budget to shut down La Scintilla, not before he was yet again arrested in Trieste for attacking Giovanni Giolitti as instigator of the Italo-Turkish War.

Michele Bianchi's attitude during World War I mirrored that of Benito Mussolini: he became an active supporter of Italy's entry into the conflict, and advocate of irredentism.

With the end of the war, Bianchi joined Mussolini's Fasci italiani di combattimento, and then the National Fascist Party (Partito Nazionale Fascista, or PNF).

After stomping out a strike action against Fascist maneuvers, Bianchi was one of the Quattuorvirate who led the March on Rome, the pseudo-coup d'état that brought Mussolini as prime minister (October 1922).

"[5] In short time, Bianchi was dismissed as PNF leader in 1923, while joining the Grand Council of Fascism; in 1924, he was elected to the Chamber of Deputies, but resigned from his government position on 14 March.
