Deputy Premier of the Soviet Union in the context of "Government of the Soviet Union"

Lev Davidovich Trotsky (né Bronstein; 7 November [O.S. 26 October] 1879 – 21 August 1940), better known as Leon Trotsky, was a Russian revolutionary, Soviet politician and political theorist. He was a key figure in the 1905 Revolution, October Revolution of 1917, Russian Civil War, and the establishment of the Soviet Union, from which he was exiled in 1929 before his assassination in 1940. Trotsky and Vladimir Lenin were widely considered the two most prominent figures in the Soviet state from 1917 until Lenin's death in 1924. Ideologically a Marxist and a Leninist, Trotsky's ideas inspired a school of Marxism known as Trotskyism.

Trotsky joined the Russian Social Democratic Labour Party in 1898, being arrested and exiled to Siberia for his activities. In 1902 he escaped to London, where he met Lenin. Trotsky initially sided with the Mensheviks against Lenin's Bolsheviks in the party's 1903 schism, but declared himself non-factional in 1904. During the 1905 Revolution, Trotsky was elected chairman of the Saint Petersburg Soviet. He was again exiled to Siberia, but escaped in 1907 and lived abroad. After the February Revolution of 1917, Trotsky joined the Bolsheviks and was elected chairman of the Petrograd Soviet. He helped to lead the October Revolution, and as the People's Commissar for Foreign Affairs negotiated the Treaty of Brest-Litovsk, by which Russia withdrew from World War I. He served as People's Commissar for Military Affairs from 1918 to 1925, during which he built the Red Army and led it to victory in the civil war. In 1922 Lenin formed a bloc with Trotsky against the growing Soviet bureaucracy and proposed that he should become a deputy premier, but Trotsky declined. Beginning in 1923, Trotsky led the party's Left Opposition faction, which supported greater levels of industrialisation, voluntary collectivisation and party democratisation in a shared framework with the New Economic Policy.

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 Government of the Soviet Union (Russian: Правительство СССР, Pravitel'stvo SSSR), formally the All-Union Government of the Union of Soviet Socialist Republics, commonly abbreviated to Soviet Government, was the main executive institution of government in the former Soviet Union. It was led by a chairman, but the office was commonly referred to as Premier of the Soviet Union. The premier was nominated by the Central Committee of the Communist Party of the Soviet Union (CPSU) at the 1st Plenary Session of the Supreme Soviet of the Soviet Union in the aftermath of national elections. Certain governments, such as Ryzhkov's II, had more than 100 other government members, serving as first deputy premiers, deputy premiers, government ministers or heads of state committees/commissions; they were chosen by the premier and confirmed by the Supreme Soviet. The Government of the Soviet Union exercised its executive powers in conformity with the constitution of the Soviet Union and legislation enacted by the Supreme Soviet. The first government was led by Vladimir Lenin, and the last government was led by Ivan Silayev.

Following the Treaty on the Creation of the USSR of 1922, the Russian Soviet Socialist Federative Republic, Ukrainian Socialist Soviet Republic, the Byelorussian Socialist Soviet Republic and the Transcaucasian Socialist Federative Soviet Republic established the Union of Soviet Socialist Republics (USSR). The treaty established the government, which was later legitimised by the adoption of the first Soviet constitution in 1924. The 1924 constitution made the government responsible to the Congress of Soviets of the Soviet Union. In 1936, the state system was reformed with the enactment of a new constitution. It abolished the Congress of Soviets and established the Supreme Soviet of the Soviet Union in its place. At the 1st Plenary Session of the II Supreme Soviet in 1946 the government was renamed Council of Ministers. Minor changes were introduced with the enactment of the 1977 constitution. The CPSU's 19th All-Union Conference voted in favor of amending the constitution. It allowed for multi-candidate elections, established the Congress of People's Deputies and weakened the party's control over the Supreme Soviet. Later on 20 March 1991 the Supreme Soviet on Mikhail Gorbachev's suggestion amended the constitution to establish a presidential system. The Council of Ministers was abolished and replaced by a Cabinet of Ministers that was responsible to the President of the Soviet Union. The head of the Cabinet of Ministers was the Prime Minister of the Soviet Union. The government was forced to resign in the aftermath of the 1991 Soviet coup d'état attempt, in which Prime Minister Valentin Pavlov participated in. In its place the Soviet state established what was supposed to be a transitory committee headed by Silayev to run the basic governmental functions until a new cabinet was appointed. On 26 December 1991 the Supreme Soviet dissolved the Soviet Union and therefore, the government of the Soviet Union.
