Ministries of the Soviet Union in the context of "NKVD"

The Government of the Union of Soviet Socialist Republics (USSR) was the executive and administrative organ of the highest body of state authority, the All-Union Supreme Soviet. It was formed on 30 December 1922 and abolished on 26 December 1991. The government was headed by a chairman, most commonly referred to as the premier of the Soviet Union, and several deputy chairmen throughout its existence. The Communist Party of the Soviet Union (CPSU), as "The leading and guiding force of Soviet society and the nucleus of its political system" per Article 6 of the state constitution, controlled the government by holding a two-thirds majority in the All-Union Supreme Soviet. The government underwent several name changes throughout its history, and was known as the Council of People's Commissars from 1922 to 1946, the Council of Ministers from 1946 to 1991, the Cabinet of Ministers from January to August 1991 and the Committee on the Operational Management of the National Economy from August to December 1991.

The government chairman was nominated by the Central Committee of the Communist Party of the Soviet Union (CPSU) and elected by delegates at the first plenary session of a newly elected Supreme Soviet of the Soviet Union. Certain governments, such as Ryzhkov's second government, had more than 100 government ministers, 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 Valentin Pavlov.

The Council of Ministers of the Union of Soviet Socialist Republics (Russian: Совет министров СССР, romanized: Sovet Ministrov SSSR, IPA: [sɐˈvʲet mʲɪˈnʲistrəf ˌɛsˌɛsˌɛsˈɛr]) was the highest executive and administrative organ of state authority of the Union of Soviet Socialist Republics (USSR) from 1946 until 1991.

During 1946 the Council of People's Commissars was reorganized as the Council of Ministers. Accordingly, the People's Commissariats were renamed as Ministries. The council issued declarations and instructions based on and in accordance with applicable laws, which had obligatory jurisdictional power in all republics of the Union. However, the most important decisions were made by joint declarations with the Central Committee of the Communist Party of Soviet Union (CPSU), which was de facto more powerful than the Council of Ministers. During 1991 the Council of Ministers was dissolved, and replaced by the newly established "Cabinet of Ministers", which itself disappeared only months later when the USSR was disbanded.

The Ministry of Internal Affairs of the USSR (MVD; Russian: Министерство внутренних дел СССР (МВД), romanized: Ministerstvo vnutrennikh del SSSR) was the interior ministry of the Soviet Union from 1946 to 1991. The MVD was established as the successor to the NKVD during the reform of the People's Commissariats into the Ministries of the Soviet Union in 1946 as part of a broader restructuring of the government. The MVD did not include agencies concerned with secret policing unlike the NKVD, with the function being assigned to the Ministry of State Security (MGB), which had been established during the Second World War. The MVD and MGB were briefly merged into a single ministry from March 1953 until the MGB was split off as the Committee for State Security (KGB) in March 1954.

This resulted in a system where one agency was responsible for domestic and foreign intelligence gathering, espionage, surveillance and secret police functions, and another responsible for the regular civilian police forces, fire departments and internal security troops. The MVD was headed by the Minister of Internal Affairs and responsible for many internal services in the Soviet Union such as the Militsiya, the national police force, the Internal Troops, which served as the USSR's national gendarmerie, the OMON riot control units, Traffic Safety, prisons, the Gulag system as well as the successive penal colonies, and the internal migration system. From 1966-1968, it was briefly known as the Ministry of Public Order Protection. The MVD was dissolved upon the dissolution of the Soviet Union in December 1991 and succeeded by its branches in the post-Soviet states, the largest being the Russian MVD, which inherited its predecessor's functions, though its Internal Troops would later become their own independent service - the National Guard.

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.

The first deputy premier of the Soviet Union was the deputy head of government of the Union of Soviet Socialist Republics (USSR). Despite the title, the office was not always held by a single individual. The office bore three different titles throughout its existence: First Deputy Chairman of the Council of People's Commissars (1923–1946), First Deputy Chairman of the Council of Ministers (1946–1991), and First Deputy Prime Minister of the Soviet Union (1991). The term "first deputy premier" was used by outside commentators to describe the office of first deputy head of government.

A first deputy premier was responsible for a specific policy area. For example, Kirill Mazurov was responsible for industry, while Dmitry Polyansky was responsible for agriculture in the Soviet Union. In addition, an officeholder would be responsible for coordinating the activities of ministries, state committees, and other bodies subordinated to the government. It was expected that a First Deputy gave these organs guidance in an expeditious manner to ensure the implementation of plans for economic and social development and to check if the orders and decisions of the government were being followed. If the premier could not perform his duties one of the first deputies would take on the role of acting premier until the premier's return. During the late 1970s, when the health of Premier Alexei Kosygin deteriorated, First Deputy Premier Nikolai Tikhonov acted on his behalf as during his absence. Finally, a first deputy was by right a member of the government Presidium, its highest decision-making organ.

The Ministry of General Machine-Building (Russian: Министерство общего машиностроения; MOM), also known as Minobshchemash, was a government ministry of the Soviet Union from 1955 to 1957 and from 1965 to 1991. The ministry supervised design bureaus that managed the research, development, and production of ballistic missiles as well as launch vehicles and satellites in the Soviet space program.

While Soviet rocketry organizations date back to 1921, the Ministry of General Machine-Building, upon being founded in 1955, became a dedicated department for aerospace technology. It was dissolved in 1957 but was reinstated in 1965. Various projects of the Soviet space program were developed at the ministry. It also began commercially providing launch services abroad through its Glavkosmos agency during the perestroika reforms of the late 1980s. The ministry was permanently abolished in 1991 amid the dissolution of the Soviet Union. The Russian Space Agency, which would later become Roscosmos, was created in 1992 as its successor.
