The author traces, through articles written by Gramsci during the first year and a half of release of «L'Ordine Nuovo», the development of Factory Council's doctrine. Inspired by the voluntary initiatives in Turin factories, the young Sardinian processes, since the summer of 1919, a revolutionary theory gathered on the role of working-class institutions. The extensive task of the Factory, in a materially and spiritually devastated postwar industrial society, forces the political thinker to reshape the traditional functions of the two representative proletarian institutions: Labor Union and Political Party. Only rethinking about how they work, anchored in patterns typical of the bourgeois society, it's possible to lead to success the revolutionary movement of the most aware Italian workers: from Turin industries can arise the future construction of Italian Soviet republic that, after the victory of the Revolution in all countries, will be melted in international communist society.
