1919–1943

Comintern

The Third International as it moved from world-revolution organ to instrument of Soviet policy.

Organizational Lineage

  1. Founding and the offensive years 1919–1921

    The Third International, founded in Moscow in March 1919 in the expectation of imminent European revolution. It declared itself a single world communist party, and the Twenty-one Conditions adopted at the Second Congress in 1920 forced the splits that created the communist parties of France, Italy and Germany.

  2. United front and Bolshevization 1921–1928

    After the German revolution failed, the Third Congress fell back on the united front tactic of winning the masses. Under Zinoviev's chairmanship the Fifth Congress of 1924 decreed the Bolshevization of the sections, and the faction fights of the Soviet party began to be replayed as leadership changes in every national party.

  3. Third Period 1928–1934

    The Sixth Congress of 1928 declared the final crisis of capitalism at hand and branded social democracy as social fascism. By blocking joint action between communists and social democrats, the line is counted among the reasons the German workers' movement failed to stop Hitler.

  4. Popular Front turn 1934–1939

    The shock of Hitler's victory reversed the line. Dimitrov's report to the Seventh Congress in 1935 made the anti-fascist popular front official policy, and the popular front governments of France and Spain followed. In the same years the Great Purge consumed much of the foreign communist cadre living in Moscow.

  5. Pact interlude 1939–1941

    With the Nazi-Soviet pact of August 1939 the anti-fascist line was withdrawn overnight. The war was declared an imperialist war with guilt on both sides, and the national parties bled members in the confusion of the sudden turn.

  6. War and dissolution 1941–1943

    The German invasion restored the anti-fascist line. In May 1943 Stalin dissolved the Comintern with an eye to relations with the Allies; parts of its apparatus passed to the party Central Committee's international department, and part of its role to the Cominform founded in 1947.

Grigory Yevseyevich Zinoviev

Григорий Евсеевич Зиновьев
Comintern Soviet Union Russia 1883–1936 ✕ Executed

He opposed October, vouched for Stalin, and was shot by him

May 1924, moments after Lenin's testament was read to the Central Committee. Zinoviev rose to defend Stalin: 'None of the things we feared have come to pass. Comrade Stalin has dispelled those fears.' The testament was buried; Stalin stayed.

One of Lenin's longest companions in exile and the first chairman of the Comintern, he became the face of international communism in its founding years. As chairman of the Petrograd (Leningrad) Soviet he commanded the party's northern stronghold, yet in October 1917 he publicly opposed the armed rising alongside Kamenev, clashing directly with Lenin. After Lenin's death in 1924 he formed the triumvirate with Stalin and Kamenev to block Trotsky, vowing that 'Comrade Stalin has dispelled the fears' and helping to suppress Lenin's testament. But Stalin soon cast him aside; in 1926 he joined his lifelong enemy Trotsky in the United Opposition, and after a cycle of defeats and recantations he was shot at the first Moscow show trial in 1936.

Lev Borisovich Kamenev

Лев Борисович Каменев
Comintern Soviet Union Russia 1883–1936 ✕ Executed

The party’s licensed voice of caution: his warnings outlived him

October 18, 1917: Kamenev revealed the CC's secret uprising decision in Novaya Zhizn, calling it "fatal to the revolution." Lenin demanded his expulsion as a strikebreaker. Ten days later the Bolsheviks took power — and Kamenev became the first head of the Soviet state.

One of Lenin's oldest comrades, whom he met in Paris in 1902 and trusted for over thirty years. He opposed the October 1917 rising but stayed to serve, chairing the Moscow Soviet for eight years and presiding over the Politburo during Lenin's illness. It was Kamenev who proposed Stalin as General Secretary in 1922, and with Stalin and Zinoviev formed the triumvirate that blocked Trotsky. In 1925 he broke with Stalin, declaring at the Party Congress that 'we are against creating a leader,' and lost every post. Exiled from politics, he directed the Pushkin House and the Academia publishing house, devoting himself to literary scholarship. In 1936 he stood beside Zinoviev in the dock at the first Moscow show trial, and was shot.

As Comintern Secretary from 1928 to 1943, he was Stalin's operational manager of the world communist movement: executing line changes and purges across foreign communist parties.
