Despite the Unione Sindacale Italiana (USI) adopting a neutralist resolution in August 1914, syndicalist leaders such as Alceste de Ambris rejected it.
The leaders believed that previous class-based revolts, such as the Parma general strike of 1908 or the Red Week, had failed to mobilize broad support or engage all social forces.

Simultaneously, Filippo Tommaso Marinetti's avant-garde Futurists, who held the most aggressive pro-war views, formed their own Fasci Politici Futuristi to encourage Italian involvement in the conflict.
