"In 1876, at the Berne conference of the International Working Men's Association, the Italian anarchist Errico Malatesta argued that the revolution "consists more of deeds than words", and that action was the most effective form of propaganda. In the bulletin of the Jura Federation he declared "the Italian federation believes that the insurrectional fact, destined to affirm socialist principles by deed, is the most efficacious means of propaganda". "As anarcho-communism emerged in the mid 19th century it had an intense debate with bakuninist collectivism and as such within the anarchist movement over participation in syndicalism and the workers movement as well as on other issues.So "In the theory of the revolution" of anarcho-communism as elaborated by Peter Kropotkin and others "it is the risen people who are the real agent and not the working class organised in the enterprise (the cells of the capitalist mode of production) and seeking to assert itself as labour power, as a more 'rational' industrial body or social brain (manager) than the employers.".So "between 1880 and 1890" with the "perspective of an immanent revolution," who was "opposed to the official workers' movement, which was then in the process of formation (general Social Democratisation). They were opposed not only to political (statist) struggles but also to strikes which put forward wage or other claims, or which were organised by trade unions." But "While they were not opposed to strikes as such, they were opposed to trade unions and the struggle for the eight-hour day.  This anti-reformist tendency was accompanied by an anti-organisational tendency, and its partisans declared themselves in favour of agitation amongst the unemployed for the expropriation of foodstuffs and other articles, for the expropriatory strike and, in some cases, for 'individual recuperation' or acts of terrorism."But after Peter Kropotkin along others decided to enter labor unions after their initial reservations, there remained "the anti-syndicalist anarchist-communists, who in France were grouped around Sebastien Faure's Le Libertaire.  From 1905 onwards, the Russian counterparts of these anti-syndicalist anarchist-communists become partisans of economic terrorism and illegal 'expropriations'." Illegalism as a practice emerged and within it "The acts of the anarchist bombers and assassins ("propaganda by the deed") and the anarchist burglars ("individual reappropriation") expressed their desperation and their personal, violent rejection of an intolerable society. Moreover, they were clearly meant to be exemplary , invitations to revolt."Proponents and activists of these tactics among others included Johann Most, Luigi Galleani, Victor Serge, Giuseppe Ciancabilla and Severino Di Giovanni. The Italian Giuseppe Ciancabilla (1872–1904) wrote in "Against organization" that "we don't want tactical programs, and consequently we don't want organization. Having established the aim, the goal to which we hold, we leave every anarchist free to choose from the means that his sense, his education, his temperament, his fighting spirit suggest to him as best. We don't form fixed programs and we don't form small or great parties. But we come together spontaneously, and not with permanent criteria, according to momentary affinities for a specific purpose, and we constantly change these groups as soon as the purpose for which we had associated ceases to be, and other aims and needs arise and develop in us and push us to seek new collaborators, people who think as we do in the specific circumstance."
