Between May 18 and 20, 1888, an "expanded" Congress of the Federation of Workers of the Spanish Region was held in Barcelona, but it was not attended by the Andalusian federations which had already opted for anarcho-communism and illegalism. The delegates, the vast majority of whom were Catalan, and the Federal Committee decided to create the Spanish Federation of Resistance to Capital, better known by the name of the Union and Solidarity Pact, whose purpose was "to unite in a common action the resistant force of the Spanish proletariat to direct it against the prevailing capitalism ..." For this purpose, "unconditional support for any strike promoted by workers to safeguard their outraged dignity or to improve their working conditions" was approved, although it was recommended that strikes only be carried out "under favorable conditions". The new organization, according to Tuñón de Lara, "was halfway between anarchism and societarism". However, according to Josep Termes, it was rather contrary to societarism, as the following statement would prove: "Understand well, we are talking about spontaneous and natural resistance, not that which presupposes a universal, patient and calculated organization, to get a few more cents in wages or an hour less work… This kind of resistance is as ineffective and impractical as cooperation."
