of the revolutionary wave in Europe and internal struggles within the Bolshevik Party and the Comintern after Lenin's death and before Stalin's absolute consolidation of power. The Third Period (1929–1934), an ultra-left turn which saw rapid industrialization and collectivization in the Soviet Union under Stalin's rule, the refusal by communists to cooperate with social democrats in other countries (labeling them social fascists) and the ultimate rise of Adolf Hitler in Germany which led to the abandonment of the hard-line policy of this period. These years also saw the complete subordination of all communist parties across the world to the directives of the All-Union Communist Party (Bolsheviks), making the Comintern more or less an organ of the Communist Party of the Soviet Union. The Popular Front period (1934–1939) which marked the call by Comintern to all popular and democratic forces (not just communist) to unite in popular fronts against fascism. Products of this period were the popular front governments in the French Third Republic and the Second Spanish Republic. However, this period was also marked by widespread purges of anyone suspected as an enemy of the Stalinist regime, both in the Soviet Union and abroad. These mass purges resulted in the breaking up of the Popular Front in Spain amidst the Spanish Civil War and the fall of Spain to Francisco Franco. The period of advocating peace (1939–1941), a result of the signing of the Molotov–Ribbentrop Pact which resulted in the Soviet invasion of Poland. In this period, communists were advocating non-participation in World War II, labeling the war as imperialist. The term revolutionary defeatism was used by Comintern in this period to refer to anti-war propaganda by communists in Western Europe against their national governments. The Eastern Front period, sometimes called the Second Popular Front (1941–1943), was the last period of the Comintern, starting immediately after the German invasion of the Soviet Union, with Stalin's 3 July 1941 call to the entire free world to unite and fight Nazism by all means. This was a period of militant anti-fascism, the emergence of national liberation movements all across occupied Europe and ultimately the dissolution of the Comintern in 1943. The Early Cold War (1947–1960) in which the Soviet Union and the Red Army installed the Eastern Bloc communist regimes in most of Eastern Europe (except for Yugoslavia and Albania, which had independent communist regimes).
