Soon after Lenin's death, Stalin joined Zinoviev and Kamenev in a Politburo Triumvirate. By 1924 they were united in wanting to get rid of the troublesome Trotsky. But this was no easy task. Trotsky had developed the Red Army and had played a huge role during the October Revolution. Stalin used Zinoviev and Kamenev to combat Trotsky, while appearing as "The Golden Centre Man". There are multiple theories on the hostility between Stalin and Trotsky, and when it began. But a huge "political" divider became Stalin's idea of "Socialism in One Country" vs Trotsky's "Permanent Revolution". Stalin's idea, in the mid-1920s, was actually revolutionary in itself. The entire Bolshevik concept had been to begin at home, in Russia, and then "export" the revolution to the West. By 1925 it had become apparent that all revolutionary movements in Germany and elsewhere had failed. In Italy even a counterrevolutionary movement, Fascism, had come to power. Trotsky was first removed as Commissar for Military and Naval Affairs (January 1925), removed from the Politburo (October 1926), removed from the Central Committee (October 1927), expelled from the Communist Party (November 1927), exiled to Alma–Ata in Kazakhstan (January 1928), and exiled from the Soviet Union (February 1929).
