The Communist Party of the Soviet Union (CPSU), at some points known as the Russian Communist Party (Bolsheviks) and All-Union Communist Party (Bolsheviks), sometimes referred to as the Soviet Communist Party (SCP), and formerly known as the Bolshevik Party, was the founding and ruling political party of the Soviet Union. The CPSU was the sole governing party of the Soviet Union until 1990 when the Congress of People's Deputies modified Article 6 of the 1977 Soviet Constitution, which had previously granted the CPSU a monopoly over the political system. The party's main ideology was Marxism-Leninism.
The Supreme Soviet of the Union of Soviet Socialist Republics was, beginning in 1936, the highest body of state authority of the Union of Soviet Socialist Republics (USSR), and based on the principle of unified power was the only branch of government in the Soviet state. Prior to 1936, the Congress of Soviets was the supreme legislative body. During 1989–1991 a similar, but not identical structure was the supreme legislative body. The Supreme Soviet appointed the Council of Ministers, the Supreme Court, and the Procurator General of the USSR as well as elected the Presidium which served as the USSR's collective head of state by the both 1936 and 1977 Soviet Constitution.
The president of the Soviet Union, officially the president of the Union of Soviet Socialist Republics, abbreviated as president of the USSR, was the head of state of the Union of Soviet Socialist Republics from 15 March 1990 to 25 December 1991.
The Congress of Soviets was the supreme governing body of the Russian Soviet Federative Socialist Republic and several other Soviet republics from 1917 to 1936 and a somewhat similar Congress of People's Deputies from 1989 to 1991. After the creation of the Soviet Union, the Congress of Soviets of the Soviet Union functioned as its legislative branch until its dissolution in 1936. Its initial full name was the "Congress of Soviets of Workers', Soldiers' and Peasants' Deputies". It was also sometimes known as the "Congress of People's Deputies." A similar name also applied in communist-held China in the Republican era.
The political system of the Soviet Union took place in a federal single-party soviet socialist republic framework which was characterized by the superior role of the Communist Party of the Soviet Union (CPSU), the only party permitted by the Constitution.
The All-Russian Central Executive Committee (ARCEC) was the highest legislative, administrative and revising body of the Russian Soviet Federative Socialist Republic from 1917 until 1937. Although the All-Russian Congress of Soviets had supreme authority in the RSFSR, in periods between Congress sessions its powers passed to the VCIK.
The Congress of People's Deputies of the Russian SFSR and since 1992 Congress of People's Deputies of the Russian Federation was the supreme government institution in the Russian SFSR and in the Russian Federation from 16 May 1990 to 21 September 1993. Elected on 4 March 1990 for a period of five years, it was dissolved by presidential decree during the Russian constitutional crisis of 1993 and ended de facto when the Russian White House was attacked on 4 October 1993. The Congress played an important role in some of the most important events in the history of Russia during this period, such as the declaration of independence of Russia from the USSR, the rise of Boris Yeltsin, and economic reforms.
The electoral system of the Soviet Union was varying over time, being based upon Chapter XIII of the provisional Fundamental Law of 1922, articles 9 and 10 of the 1924 Constitution and Chapter XI of the 1936 Constitution, with the electoral laws enacted in conformity with those. The Constitution and laws applied to elections in all Soviets, from the Supreme Soviet of the Soviet Union, the Union republics and autonomous republics, through to regions, districts and towns. Voting was claimed to be secret and direct with universal suffrage. However, in practice, before 1989, voters could vote against candidates preselected by the Communist Party only by spoiling their ballots, whereas votes for the party candidates could be cast simply by submitting a blank ballot. A person would be given a ballot by a clerk, and could immediately walk to the ballot box, and while there were booths in which one could strike the candidates they voted against off the ballot, this was easy to record and was not commonly done by voters.
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.
In 1989, elections were held for the Congress of People's Deputies of the Soviet Union. The main elections were held on 26 March and a second round on 9 April. They were the first partially free nationwide elections held in the Soviet Union, and would prove to be the final national elections held as the country dissolved in 1991. The elections were followed by regional elections in 1990, the last legislative elections to take place in the country.
The Congress of People's Deputies of the Soviet Union was the highest body of state authority of the Soviet Union from 1989 to 1991.
The Ukrainian People's Republic of Soviets was a short-lived (1917–1918) Soviet republic of the Russian SFSR that was created by the declaration of the Kharkov All-Ukrainian Congress of Soviets "About the self-determination of Ukraine" on 25 December [O.S. 12 December] 1917 in the Noble Assembly building in Kharkov. Headed by the Provisional Workers' and Peasants' Government of Ukraine formed earlier in Russian Kursk. The republic was later united into the Ukrainian Soviet Republic and, eventually, liquidated, because of a cessation of support from the government of the Russian SFSR when the Treaty of Brest-Litovsk was signed.
The All-Ukrainian Congress of Soviets was the supreme governing body of the Ukrainian Soviet Socialist Republic from 1917–38. From 1922 to 1938 the Constitution of the Ukrainian SSR, modeled on the 1918 Russian Constitution, mandated that Congress to be convened at least twice a year. The 1926 Constitution lowered the minimum to once a year.
The All-Russian Congress of Soviets evolved from 1917 to become the supreme governing body of the Russian Soviet Federative Socialist Republic from 1918 until 1936, effectively. The 1918 Constitution of the Russian SFSR mandated that Congress shall convene at least twice a year, with the duties of defining the principles of the Soviet Constitution and ratifying peace treaties. The October Revolution ousted the provisional government of 1917, making the Congress of Soviets the sole, and supreme governing body. This Congress was not the same as the Congress of Soviets of the Soviet Union which governed the whole Soviet Union after its creation in 1922.
The All Russian Constituent Assembly was a constituent assembly convened in Russia after the February Revolution of 1917. It met for 13 hours, from 4 p.m. to 5 a.m., 18–19 January [O.S. 5–6 January] 1918, whereupon it was illegally dissolved by the Bolshevik-led All-Russian Central Executive Committee, proclaiming the Third All-Russian Congress of Soviets the new governing body of Russia.
The Petrograd Soviet of Workers' and Soldiers' Deputies was a city council of Petrograd, the capital of Russia at the time. For brevity, it is usually called the Petrograd Soviet.
The presidency of Boris Yeltsin began with his first inauguration on 10 July 1991, and ended on 31 December 1999 when he announced his resignation. A referendum held on 17 March 1991 approved the creation of the post of president of Russia; Yeltsin was elected Russia's first president in a presidential election held on 12 June 1991.
The Second All-Russian Congress of Soviets of Workers' and Soldiers' Deputies was held on November 7–9, 1917, in Smolny, Petrograd. It was convened under the pressure of the Bolsheviks on the All-Russian Central Executive Committee of the First Congress of Soviets of Workers' and Soldiers' Deputies.
The All-Russian Central Executive Committee of the Soviets of Workers' and Soldiers' Deputies was a permanent body formed by the First All-Russian Congress of Soviets of Workers' and Soldiers' Deputies.
