This chapter brings Nehru’s relationship with the LAI to a crisis point. It examines the second world congress of the LAI in Frankfurt where many communist members launched an attack on their non-communist colleagues. The shift was emblematic of the Comintern’s directives for communists to abandon the united front strategy and alliances with socialists and nationalists in the colonies. By reading the archival record of the Frankfurt Congress, however, the picture is more complex. Not all communists within the LAI subscribed to the dictates imparted by Moscow, and instead many communists and non-communists continued to work together to chart a future for the LAI beyond the sectarianism introduced by Moscow’s third period. The eventual split between Nehru and the LAI in 1930 was informed less by sectarianism in Frankfurt and more by the INC’s retreat on the goal of independence in 1929. Even after the split, however, this chapter concludes that Nehru and his comrades never fully closed the door on reconciliation and future collaboration for the greater cause of anti-imperialism, although such cooperation would never take place under the more rigid institutional framework of the LAI.
