This article analyses the transition of the Communist Party of Chile's (CCP) policies, from the ultra-left and sectarian "class against class" policy practiced until 1934 to the Popular Front policy of broad anti-fascist, anti-oligarchic and anti-imperialist unity. The great turning-point of the CCP in 1935 is studied, the internal resistances to the change promoted by the Communist International, the concurrences and disagreements between the Chilean communist cadres and Komintern leaders, the relationship between national and international factors in this change of strategy. Furthermore, it examines the tactical provisions implemented by the CCP to achieve union unity and the formation of the Popular Front, the successive variations and theoretical adaptations of the party line, the way the new line was consolidated until 1937 and the indefinite postponement of their socialist goals.
