Smilga then embarked on a career in economic planning, as deputy chairman of VSNKh
(1921–1928) and Gosplan (1925–1926). He was restored to the Central Committee in 1925, but in 1927 he joined the United Opposition of Trotsky, G. E. Zinov′ev, and L. B. Kamenev, authoring the economic program of the group. He was consequently expelled from the party and exiled to Khabarovsk for 15 years. He was briefly allowed to return to the fold (as a member of the presidium of VSNKh) in 1930, when Stalin’s regime adopted a Leftist program of rapid industrialization, and he publicly recanted his criticisms of the leadership, but soon fell from favor again, and, on 1 January 1935, in the aftermath of the assassination of S. M. Kirov, he was yet again arrested and then sentenced to five years’ imprisonment. On 10 January 1938, Smilga was charged with “membership of a terrorist organization” by the Military Collegium of the Supreme Court of the USSR, found guilty, and sentenced to death. The sentence was carried out the same day. He was posthumously rehabilitated on 3 April 1987.SMIRNOV, IVAN NIKITOVICH (NIKITICH) (1881–25 August 1936).

Kolchak in Siberia and in the negotiation of a truce with the forces of the Political Center at Irkutsk in January 1920. He was also a founding member of the Revvoensovet of the Republic (6 September 1918–8 July 1919), where he became a spokesman for the Military Opposition to L. D. Trotsky’s administration of the Red Army. (It was Smirnov who made the Opposition’s keynote address to the Eighth Party Congress in March 1919 that won some concessions.) He was also made chairman of the Russian Communist Party (Bolsheviks)’s Siberian Revolutionary Committee (27 August 1919–29 August 1921), in which capacity he was responsible for extinguishing peasant resistance to Soviet rule in Siberia and oversaw the operation that captured Baron R. F. Ungern von Sternberg. Subsequently (1921–1923), he managed the armaments industry for VSNKh. He became a full member of the Central Committee of the RKP(b) in April 1920, but lost his seat in March 1921, having sided with Trotsky on the trade union question.
