He then set about organising the Catalan workers' movement along anarchist lines, emphasising decentralisation and federalism, eventually affiliating the FRE-AIT with Mikhail Bakunin's Anti-Authoritarian International.

[1] The declarations were openly supported by Rafael Farga i Pellicer, who at that time worked as a printer, and who began writing for the societies' newspaper La Federación.

[3] By this time, the Italian anarchist Giuseppe Fanelli was travelling to Spain in order to establish a Spanish section of the International Workingmen's Association (IWA).

Although Farga and Sentiñon aligned themselves with Bakunin's anti-political and decentralist program, they were cautious about applying it in Catalonia, where socialism had not yet fully developed and where they wished to "avoid future divisions" over these issues.

[16] The Congress was opened by Farga, who declared:[17] Comrade delegates: those of you who gather here to affirm the great work of the International Workingmen's Association, which contains within itself the complete emancipation of the proletariat and the absolute extirpation of all injustices which have ruled and still rule over the face of the earth; those of you who come to fraternize with the millions of workers, white slaves and black slaves, under the red banner which covers us; dear brothers, in the name of the workers of Barcelona, peace and greetings!As the congress continued, Farga continued to make explicitly anarchist speeches against capitalism, the state and the church, to the rapturous applause of the attending delegates.

[20] At the subsequent St. Imier Congress, Farga and his fellow delegate Tomás González Morago decided to formally affiliate the FRE-AIT with Bakunin's Anti-Authoritarian International.

[21] Within the Anti-Authoritarian International, Farga became associated with the syndicalist wing, which advocated for the general strike as a means to bring about a social revolution that would result in anarchy.
