(Federacion Anarquista Iberica) - loose federation of anarchist groups in Spain and Portugal, formed in 1927. Primary purpose was to combat reformist tendencies in the CNT and maintain it's anarchist profile. Also acted as the 'armed wing' of the CNT at the time employers were hiring pistoleros to murder leading CNT members. In so far as the FAI had a theory about the role of a revolutionary organisation it was a belief that a minority could, by insurrection, light a spark that would inflame the masses for revolution. They organised risings in January 1932, January 1933 and December 1933 all of which were unsuccessful.
