Third Period

The Third Period is an ideological concept adopted by the Communist International (Comintern) at its Sixth World Congress, held in Moscow in the summer of 1928.

The Comintern's theory was based on its economic and political analysis of world capitalism, which posited the division of recent history into three periods. 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.

Communist policies during the Third Period were marked by extreme hostility to political reformism and political organizations espousing it as an impediment to the movement's revolutionary objectives. In the field of trade unions, a move was made during the Third Period towards the establishment of radical dual unions under communist party control rather than continuation of the previous policy of attempting to radicalize existing unions by "boring from within."

The rise of the Nazi Party to power in Germany in 1933 and the annihilation of the organized communist movement there shocked the Comintern into reassessing the tactics of the Third Period. From 1934, new alliances began to be formed under the aegis of the so-called "Popular Front." The Popular Front policy was formalized as the official policy of the world communist movement by the Seventh World Congress of the Comintern in 1935.
