Francesc Tomàs Oliver

[2] He participated in representation of the Balearic Islands in the 1870 Barcelona Workers' Congress from which the Spanish Regional Federation of the IWA (FRE-AIT) arose, assuming the anarcho-collectivist theses of Mikhail Bakunin's International Alliance of Socialist Democracy.

He was re-elected in the Córdoba Congress for which he intervened in the Petroleum Revolution of Alcoy of July 1873; he was part of the AIT commission that met with the mayor Agustí Albors.

When the troops were about to enter the city, he left Alcoy to go to Madrid along with the rest of the Federal Commission, of which he continued to form part during the clandestine period (1874-1881).

After leaving the Federal Commission due to the internal crisis experienced by the FTRE as a result of the Mano Negra affair, he began to write in La Revista Social the series of articles that would form the first history of the beginnings of anarchism in Spain, and that would be published in book form in A Coruña in 1893 with the title Del nacimiento de las ideas anárquico-colectivista en España (English: On the birth of anarchic-collectivist ideas in Spain).

[2] After the disappearance of the FTRE, he remained faithful to his anarcho-collectivist ideas and in 1900 he was elected president of the Madrid workers' society "El Porvenir del Obrero".
