The Left Opposition was a faction within the Russian Communist Party (Bolsheviks) from 1923 to 1927 headed de facto by Leon Trotsky. The Left Opposition was formed by Trotsky to mount a struggle against the bureaucratic degeneration that began within the party leadership headed by Stalin during the serious illness of the Bolshevik founder Vladimir Lenin. The degeneration intensified after Lenin's death in January 1924.
