Communist International adopts Third Period policy

The Communist International, under Stalin's leadership, shifted its strategy from a united front approach to the ultra-left Third Period policy. This transition marked a significant ideological change, emphasizing aggressive confrontation with social democracy. The Third Period policy characterized social democratic leaders as 'social fascists,' which contributed to a deepening divide within the working class. This division occurred during a crucial period when unity among leftist factions was essential for countering the rising threat of fascism. The Communists' alignment with this aggressive stance led to instances where they collaborated with far-right parties, such as voting alongside the Nazis in the Prussian Landtag. This collaboration was a stark departure from previous strategies aimed at uniting various leftist groups against common adversaries, ultimately weakening the left's position in the political landscape.
