With Carrillo’s name on the cover, Octubre was reissued with a reply to Prieto. Largo Caballero’s friend Enrique de Francisco wrote to Prieto to say that he had no right to make party policy in bourgeois newspapers. Prieto replied that the same moralistic view had not inhibited the Socialist Youth from advocating bolshevization. More stridently, the journalist Carlos de Baraibar, in consultation with Largo Caballero, prepared a book attacking the ‘false socialist positions’ of Prieto. In criticizing him for breaking party discipline by publicizing his ideas, Baraibar conveniently forgot that the FJS had not hesitated to broadcast its controversial views.28 The extremism of the FJS was seriously dividing Spanish socialism. While the repressive policies of the CEDA–Radical government and the existence of thousands of political prisoners made revolutionary propaganda attractive, they also ensured a sympathetic mass response to Prieto’s call for unity and a return to the progressive Republic of 1931–3. An indication of the bitterness being engendered was shown in the summer of 1935 when the Caballeristas produced a legal weekly newspaper called Claridad. Its pages loudly backed the FJS call for the expulsion of the Besteiristas and the marginalization of the Prietistas.29 Democracia responded by arguing that the bolshevization campaign was just a smokescreen to divert attention from the FJS’s failures in October 1934. When Saborit made the gracious gesture of visiting the prisoners in the Cárcel Modelo, Largo Caballero rudely refused to shake his hand or even speak to him.30
Everything changed after the Seventh Congress of the Comintern was held in Moscow in August 1935. The secretary general, Giorgi Dimitrov, launched a call for proletarian unity and a broad popular front of all anti-fascist forces. Already, in a speech on 2 June, the PCE secretary general, José Díaz, had openly called for union with the PSOE. On 3 November, he declared that the Seventh Congress showed the need for a Popular Front.31 Carrillo was delighted. In prison, he and Hernández Zancajo lived in close proximity to their comrades from the UJC, Trifón Medrano and Jesús Rozado. They were aware that in October 1934 there had been some collaboration on the ground between the rank-and-file militants of their respective organizations. Now their daily encounters and discussions favoured the eventual unification of their organizations.32
The FJS delegate at the Comintern congress, José Laín Entralgo, reported back enthusiastically that the Communist union, the Confederación General de Trabajo Unitaria (CGTU), would amalgamate with the UGT. He also claimed that the switch of tactics meant that Moscow had returned sovereignty to the various national parties and that there was therefore no longer any reason why the FJS should not join the Comintern.33 Carrillo was already trying to secure the incorporation of the Trotskyist Bloc Obrer i Camperol and the Communist Youth into the PSOE as part of the process of bolshevizing the party. Writing in Leviatán, Araquistáin rightly suggested that Moscow’s fundamental objective with the Popular Front tactic was to ensure that liberal and left-wing anti-fascist governments would be in power in the West to ensure favourable alliances should Germany declare war on the USSR. Far from breaking with the old Comintern habit of dictating the same policy for each country, as the FJS fondly thought, the new tactic confirmed the dictatorial customs of the Third International. Araquistáin accepted the need for proletarian unity but rejected the notion of alliance with the bourgeois left.34
Largo Caballero was keen on working-class unity as long as it meant the absorption of the Communist working-class rank and file into the UGT. However, he remained hostile to an electoral coalition with the Left Republicans and, like Araquistáin, he opposed the idea of the PSOE joining the Comintern.35 For this reason, Carrillo had to be circumspect in all the negotiations with the imprisoned UJC members and crucially with the most senior Comintern representative in Spain, the Argentinian Vittorio Codovila, codenamed ‘Medina’. The director of the Cárcel Modelo turned a blind eye as Codovila was smuggled into the prison as part of a family party visiting Carrillo. Codovila was surprised by Carrillo’s readiness to accept all of the conditions requested by the Communists. All he wanted in return was for the name of the new organization to be the Juventudes Socialistas Unificadas. His reasoning was that if the FJS lost the word ‘Socialista’ from its title, it would lose its seat on the PSOE executive and be less able to continue the struggle to purge Prieto and bolshevize the party.36
On the first anniversary of the October insurrection, the FJS had issued a circular signed by Santiago Carrillo authorizing its local sections to draft joint manifestos with the UJC but not to organize joint commemorations since the PSOE had decreed that the FJS could hold joint events only with other Socialist organizations. The circular noted regretfully that the PSOE had in fact made no arrangements to celebrate the anniversary. However, it recommended that local FJS sections organize their own publicity for the anniversary and to do so stressing that ‘October had been a proletarian movement to conquer power’, that the Socialist Party had been its only leader (something that the PSOE leadership never acknowledged) and that October had halted ‘the rise of fascism’.37
In mid-November, Carrillo received a letter from the left-wing Socialist and feminist Margarita Nelken, who was exiled in Russia. She enclosed some Soviet pamphlets including a Spanish translation of Dimitrov’s speech to the Seventh Congress of the Comintern. He thought the speech ‘magnificent’, although he still had doubts about the Comintern leader’s readiness to make an alliance with the bourgeoisie without first securing the broad unity of the working class. In the package was a copy of a photograph of Largo Caballero that had been distributed among the crowd during an event in Moscow’s Red Square. When Carrillo showed him the photo, Largo Caballero was suitably flattered. Carrillo reported back that ‘the boss is in magnificent form, without any hesitation going further every day in the same direction as the Juventudes’.38
Meanwhile, on 14 November, Manuel Azaña, writing on behalf of the various Left Republican groups, formally proposed an electoral alliance to the PSOE executive. Faced with a dramatic choice, Largo Caballero quickly convoked a joint session of the PSOE, UGT and FJS executives for 16 November. Azaña’s proposal was accepted after Largo Caballero had acknowledged the absurdity of repeating the error of 1933. Carrillo and Amaro del Rosal followed the Comintern line and also spoke strongly in favour of the electoral alliance. Carlos Hernández Zancajo, however, opposed it. He thereby anticipated divisions inside Caballerista ranks that would seriously damage the Socialist movement during the Civil War, between those unswervingly committed to the Soviet Union and those, like Hernández Zancajo, for whom revolutionary politics were not understood as synonymous with Soviet interests. Determined that dealings with the bourgeois Republicans should not strengthen the Prietista wing of the Socialist movement, Largo Caballero insisted that any coalition should extend to other working-class organizations including the Communist Party. Carrillo was delighted. The UGT executive decided to open negotiations with the PCE for the incorporation of the Communist CGTU into the UGT. Moreover, Largo Caballero insisted that the Popular Front electoral programme should be approved by the PCE and the CGTU as well as by the FJS, the PSOE and the UGT.39 In contrast, Prieto feared that the disproportionate weight
