These included a "First Period" that followed World War I and saw the revolutionary upsurge and defeat of the working class, as well as a "Second Period" of capitalist consolidation for most of the decade of the 1920s. According to the Comintern's analysis, the current phase of world economy from 1928 onward, the so-called "Third Period," was to be a time of widespread economic collapse and mass working class radicalization. This economic and political discord would again make the time ripe for proletarian revolution if militant policies were rigidly maintained by communist vanguard parties, the Comintern believed.
