Like most Old Bolsheviks, he did not survive the Great Purge. Krestinsky joined the Russian Social Democratic Labor Party in 1903 and sided with its Bolshevik faction. After the February Revolution, which overthrew monarchy in Russia, he proved to be a capable organizer and was elected to the Central Committee of the Bolshevik party on 3 August 1917 (Old Style).
