Lenin's Death and the Soviet Succession Struggle

Vladimir Lenin died on 21 January 1924, following a series of strokes that had incapacitated him since 1922. His death opened a succession crisis in a state that had no constitutional mechanism for leadership transfer — the Bolshevik party had always been personally led, and no successor had been designated. Lenin's final writings — the so-called 'Lenin Testament' — recommended removing Stalin as General Secretary of the Communist Party, citing his concentration of power, rudeness, and willingness to abuse authority. The testament was suppressed by the party leadership (with Stalin's connivance) and never published in the USSR during the Soviet era. The succession struggle proceeded through several phases. In 1924–25, Stalin allied with Zinoviev and Kamenev against Trotsky, using his control of party appointments to stack congresses and committees with loyalists. Trotsky — whose prestige was enormous but whose political skills were maladroit — was progressively marginalised, removed from his military command, and expelled from the party in 1927. With Trotsky defeated, Stalin turned on his former allies. Zinoviev and Kamenev were expelled in 1927; Bukharin — who had allied with Stalin against the Left — was defeated in 1928–29 over agricultural policy (Bukharin opposed rapid collectivisation; Stalin reversed his previous position to pursue it). By 1929 Stalin had complete control of the party apparatus, the state security services, and the military, without any institutional checks on his authority. The succession struggle was decisive in establishing the character of Stalinism: a personal dictatorship operating through party loyalty, ideological rigidity, and terror, rather than through any collegial or constitutional mechanism. Trotsky went into exile and was assassinated in Mexico in 1940 by a Stalinist agent.
