Leader of the Workers' Opposition, defeated by Lenin, devoured by the Purge

At his closed Military Collegium trial on 2 September 1937 he pleaded not guilty, refusing to confess to the terrorist conspiracy or to implicate others. He maintained that the programme of the Workers' Opposition had been right.

A skilled metal turner born into a poor Old Believer family in Murom, he joined the RSDLP in 1901 and sided with the Bolsheviks after the 1903 split. Working in French, German and British factories, he absorbed the European labor movement firsthand and ran the party's clandestine Scandinavian courier network during the war. In February 1917 he was the most senior Bolshevik in the capital, active in the Russian Bureau of the CC and the Petrograd Soviet's executive committee. After October he became the first People's Commissar of Labor, laying the foundations of the eight-hour day; at the end of the Civil War he and Kollontai led the Workers' Opposition, which Lenin defeated at the Tenth Congress in 1921. Sidelined into diplomacy, expelled in 1933 and imprisoned in 1935, he was executed on 2 September 1937 on fabricated charges. Rehabilitated in 1963 and restored to the party in 1988.

The metalworker who co-led the Workers' Opposition, defeated by the party machine, consumed by the Purge

A Bolshevik metalworker from a poor peasant family near Moscow, he became a turner at the Obukhov factory at thirteen. During WWI he helped Shlyapnikov organize the Russian Bureau of the Bolshevik CC in Petrograd and formed the Achinsk Soviet in 1917. After the Civil War he co-led the Workers' Opposition with Shlyapnikov from the Metalworkers' Union CC, demanding trade union control of the economy and working-class democracy within the party. He co-signed the 'Letter of the Twenty-Two' to the Comintern in 1922 protesting the suppression of worker voices, was expelled in 1933, and refused to confess at his 1937 trial before being shot.

The polemicist who survived trial only to die in prison

"Do you know the difference between Stalin and Moses? Moses led the Jews out of Egypt, but Comrade Stalin led them out of the Politburo." — Radek to Boris Bazhanov, after Trotsky and Zinoviev were expelled from the Politburo.

A Polish-born Jewish journalist and diplomat who moved between the international social-democratic and communist movements. A close associate of Lenin, he participated in the Brest-Litovsk negotiations and the founding of the Comintern, serving on the Bolshevik Central Committee and as Comintern secretary. Renowned for his sharp polemics and biting wit, he led the Left Opposition before recanting publicly in 1930 and rejoining the Party. During the Great Purge he became the central defendant at the Second Moscow Trial, delivering theatrical confessions that earned him a 10-year sentence; in 1939 he was killed in prison on Stalin's orders.

The theorist of primitive socialist accumulation

Victor Serge recalled: "He had driven himself so hard that during meetings it seemed he might at any moment drop off to sleep; but his brain was still fresh, and crammed with statistics."

A Bolshevik economic theorist and co-author, with Bukharin, of The ABC of Communism (1919), the foundational textbook of early communist parties worldwide, he served as a Central Committee Secretary during state-building. As an initiator of the Declaration of 46 (1923) and the Left Opposition's chief polemicist, he formalized the theory of 'primitive socialist accumulation' in The New Economics (1926), arguing that surplus must be transferred from the peasant sector to fund industrialization, framing the NEP debate. He returned to the Stalin line in 1929 but soon broke over collectivization violence, joined an underground opposition group, and was executed in 1937.

From Moscow uprising artillery commander to Left Communist and Democratic Centralist

Building socialism in pre-industrial Russia alone was 'a side turning off the main highway of European socialism' — foredoomed to failure.

A Moscow law student and Bolshevik from 1907, he formed a Marxist theorists' trio with Nikolai Bukharin and Valerian Osinsky. In October 1917 he commanded the heavy artillery that secured Bolshevik victory in Moscow, and served as People's Commissar of Trade and Industry in early 1918. A Left Communist opponent of Brest-Litovsk, he spent the next decade in successive oppositions (Democratic Centralist, signatory of the Declaration of 46, and United Opposition ally of Trotsky, Zinoviev, and Kamenev) consistently pressing for party democracy. From 1921–1927 he sat on the Gosplan Presidium, chaired the Vesenkha financial commission, served on the Council of Labor and Defense, and edited Pravda. He regarded Russian socialism in isolation as 'a side turning off the main highway of European socialism, foredoomed to failure,' and after expulsion declared the revolution dead under Stalin.

Left SR who organised the 1918 assassination of the German field marshal Eichhorn in Kiev and spent decades in Soviet prisons and exile

In 1918, she and Boris Donskoy prepared the assassination of German occupation commander Hermann von Eichhorn in Kiev; her attempt to kill Hetman Skoropadskyi failed.

A grandniece of the Decembrist Pyotr Kakhovsky, she joined the SR Maximalists after 1905 and in 1908 was sentenced to hard labour, which she served at Nerchinsk alongside Maria Spiridonova. After the October Revolution she went with the Left Socialist-Revolutionaries and sat on the presidium of the Second Congress of Soviets. When the Left SR leadership resumed terror against the Brest-Litovsk peace in 1918, she and Boris Donskoy prepared the killing of Field Marshal Eichhorn in Kiev; her attempt on Hetman Skoropadskyi failed, and the Germans sentenced her to death but released her in January 1919. From 1921 she passed through Soviet exile, the 1937 "All-Union SR Centre" trial and the Krasnoyarsk camps, was released in 1954 and spent her last years keeping alive the memory of Spiridonova and Izmailovich.
