All-Russian Congress of Soviets in the context of "Supreme organ of state power"

The Socialist Revolutionary Party (SR; Russian: Па́ртия социали́стов-революционе́ров, romanized: Pártiya sotsialístov-revolyutsionérov,, lit. 'Party of Socialists-Revolutionaries') was a major socialist political party in the late Russian Empire, during both phases of the Russian Revolution, and in early Soviet Russia. The party members were known as Esers (эсеры, esery, from "SRs").

The SRs were agrarian socialists and supporters of a democratic socialist Russian republic. The ideological heirs of the Narodniks, the SRs won a mass following among the Russian peasantry by endorsing the overthrow of the Tsar and the redistribution of land to the peasants. The SRs boycotted the elections to the First Duma following the Revolution of 1905 alongside the Russian Social Democratic Labour Party, but chose to run in the elections to the Second Duma and received the majority of the few seats allotted to the peasantry. Following the 1907 coup, the SRs boycotted all subsequent Dumas until the fall of the Tsar in the February Revolution of March 1917. Controversially, the party leadership endorsed the Russian Provisional Government and participated in multiple coalitions with liberal and social-democratic parties, while a radical faction within the SRs rejected the Provisional Government's authority in favor of the Congress of Soviets and began to drift towards the Bolsheviks. These divisions would ultimately result in the party splitting over the course of the fall of 1917, with the emergence of a separate Party of Left Socialist Revolutionaries. Meanwhile, Alexander Kerensky, one of the leaders of the February Revolution and the second and last head of the Provisional Government (July–November 1917) was a nominal member of the SR party but in practice acted independently of its decisions.

The Party of Left Socialist-Revolutionaries-Internationalists (Russian: Партия левых социалистов-революционеров-интернационалистов, romanized: Partiya levykh sotsialistov-revolyutsionerov-internatsionalistov) was a revolutionary socialist political party formed during the Russian Revolution.

In 1917, the Socialist Revolutionary Party split between those who supported the Russian Provisional Government, established after the February Revolution and those who supported the Bolsheviks, who favoured the overthrow of the Provisional Government and the placing of political power in the hands of the Congress of Soviets. Those that continued to support the Provisional Government became known as the Right SRs while those who aligned with the Bolsheviks became known as the Left Socialist-Revolutionaries or Left SRs (Russian: левые эсеры, romanized: leviye esery). After the October Revolution, the Left SRs formed a coalition government with the Bolsheviks from November 1917 to March 1918, but resigned its position in government after the signing of the Treaty of Brest-Litovsk. The Central Committee of the Left SRs ultimately ordered the assassination of Wilhelm von Mirbach in an attempt to cause Russia to re-enter World War I and launched an ill-fated uprising against the Bolsheviks shortly after. Most members of the Left SRs were promptly arrested, though the majority that opposed the uprising were steadily released and allowed to retain their positions in the Soviets and bureaucracy. However, they were unable to reorganize the party, which gradually splintered into multiple pro-Bolshevik parties – all of which would merge with the Russian Communist Party (Bolsheviks) by 1921.

The Supreme Soviet of the Russian SFSR, later the Supreme Soviet of the Russian Federation, was the highest organ of state authority of the Russian SFSR from 1938 to 1990; between 1990 and 1993, it was the permanent organ of the Congress of People's Deputies of the Russian Federation.

The Supreme Soviet of the Russian SFSR was established to be similar in structure to the Supreme Soviet of the USSR in 1938, replacing the All-Russian Congress of Soviets as the highest organ of power of Russia.

Lev Borisovich Kamenev (né Rozenfeld; 18 July [O.S. 6 July] 1883 – 25 August 1936) was a Russian-Soviet revolutionary politician. A prominent Old Bolshevik, Kamenev was a leading figure in the early Soviet government and served as a deputy premier of the Soviet Union from 1923 to 1926.

Born in Moscow to a family active in revolutionary politics, Lev Kamenev joined the Russian Social Democratic Labour Party in 1901 and sided with Vladimir Lenin's Bolshevik faction after the party's 1903 split. He was arrested several times and participated in the failed Revolution of 1905, after which he moved abroad and became one of Lenin's close associates. In 1914, Kamenev was arrested upon returning to Saint Petersburg and exiled to Siberia. He returned after the February Revolution of 1917, which overthrew the monarchy, and joined Grigory Zinoviev in opposing Lenin's "April Theses" and an armed seizure of power within the former Russian Empire. Nevertheless, when Lenin came to power in Russia following the success of the October Revolution, Kamenev briefly served as chairman of the All-Russian Congress of Soviets along with a number of senior posts, including chairman of the Moscow Soviet and Deputy Chairman of the Council of People's Commissars. In 1919, he was elected as a full member of the first Central Committee Politburo, the supreme decision-making body of the emerging Communist Party of the Soviet Union.

The All-Russian Central Executive Committee (Russian: Всероссийский Центральный Исполнительный Комитет (ВЦИК), romanized: Vserossijskij Tsentraĺný Ispolniteĺný Komitet (VTsIK)) was (June – November 1917) a permanent body formed by the First All-Russian Congress of Soviets of Workers' and Soldiers' Deputies (held from June 16 to July 7, 1917 in Petrograd), then became the supreme governing body of the Russian Soviet Federative Socialist Republic in between sessions of the All-Russian Congress of Soviets from 1917 to 1937. In 1937, the All-Russian Central Executive Committee was replaced with the Presidium of the Supreme Soviet of the Russian SFSR.

At formation, its full name was the All-Russian Central Executive Committee of the Soviets of Workers' and Soldiers' Deputies. Later it was the All-Russian Central Executive Committee of the Soviets of Workers', Peasants', Red Army, and Cossack Deputies (Russian: Всероссийский Центральный Исполнительный Комитет Советов рабочих, крестьянских, красноармейских и казачьих депутатов).

Transmission belt is a Marxist–Leninist analogy to describe interactions of the communist party with the people in a communist state via mass organizations, such as trade unions. All these institutions worked under the party's leadership. Examples are the All-Union Central Council of Trade Unions of the Soviet Union and the All-China Federation of Trade Unions, were and are transmission belt organisations.

The term originates from Vladimir Lenin's speech to the 8th All-Russian Congress of Soviets, the All-Russian Central Council of Trade Unions and the Moscow City Council of Trade Unions, on 30 December 1920.
