Until exiled from Russia in 1929, Leon Trotsky helped develop and led the Left Opposition (and the later Joint Opposition) with members of the Workers' Opposition, the Decembrists, and (later) the Zinovievists.[17] Trotskyism ideologically predominated the political platform of the Left Opposition, which demanded the restoration of soviet democracy, the expansion of democratic centralism in the Communist Party, national industrialisation, international permanent revolution, and socialist internationalism. The Trotskyist demands countered Stalin's political dominance of the Russian Communist Party, which was officially characterised by the 'cult of Lenin', the rejection of permanent revolution, and the doctrine of Socialism in One Country. The Stalinist economic policy vacillated between appeasing capitalist kulak interests in the countryside, and destroying them.
