One-party state

The General Secretary of the Central Committee of the Communist Party of the Soviet Union was the leader of the Communist Party of the Soviet Union (CPSU). From 1924 until the country's dissolution in 1991, the officeholder was the recognized leader of the Soviet Union. Prior to Joseph Stalin's accession, the position was not viewed as an important role in Vladimir Lenin's government and previous occupants had been responsible for technical rather than political decisions.

Officially, the General Secretary solely controlled the Communist Party directly. However, since the party had a monopoly on political power, the General Secretary de facto had executive control of the Soviet government. Because of the office's ability to direct both the foreign and domestic policies of the state and preeminence over the Soviet Communist Party, it was the de facto highest office of the Soviet Union.

Vladimir Ilyich Ulyanov (22 April [O.S. 10 April] 1870 – 21 January 1924), better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist. He was the first head of government of Soviet Russia from 1917 until his death in 1924, and of the Soviet Union from 1922 until his death. As the founder of the Bolsheviks, Lenin led the October Revolution, which established the world's first communist state. His government won the Russian Civil War and created a one-party state under the Communist Party. Ideologically a Marxist, his developments to the ideology are called Leninism.

Lenin embraced revolutionary socialist politics after his brother was executed in 1887 for plotting to assassinate the Russian tsar. He was expelled from Kazan Imperial University for participating in student protests, and earned a law degree before moving to Saint Petersburg in 1893 and becoming a prominent Marxist activist. In 1897, Lenin was exiled to Siberia for three years, after which he moved to Western Europe and became a leading figure in the Russian Social Democratic Labour Party. In 1903, the party split between Lenin's Bolshevik faction and the Mensheviks, with Lenin advocating for a vanguard party to lead the proletariat in establishing socialism. Lenin briefly returned to Russia during the Revolution of 1905. During the First World War he campaigned for its transformation into a Europe-wide proletarian revolution. After the February Revolution of 1917 ousted Tsar Nicholas II, Lenin returned to Russia and played a leading role in the October Revolution.

The Communist Party of the Soviet Union (CPSU), at some points known as the Russian Communist Party (Bolsheviks) and the All-Union Communist Party (Bolsheviks), and sometimes referred to as the Bolshevik Party and Soviet Communist 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 party was outlawed under Russian president Boris Yeltsin's decree on 6 November 1991, citing the 1991 Soviet coup attempt as a reason.

The party started in 1898 as part of the Russian Social Democratic Labour Party (RSDLP). In 1903, that party split into a Menshevik (m) ("minority") and Bolshevik (b) ("majority") faction; the latter, led by Vladimir Lenin, is the direct ancestor of the CPSU and is the party that seized power in the October Revolution of 1917. Its activities were suspended on Soviet territory 74 years later, on 29 August 1991, soon after a failed coup d'état by conservative CPSU leaders against the reforming Soviet president and party general secretary Mikhail Gorbachev.

Mikhail Sergeyevich Gorbachev (2 March 1931 – 30 August 2022) was a Soviet and Russian politician who was the last leader of the Soviet Union from 1985 until the country's dissolution in 1991. He served as General Secretary of the Communist Party from 1985, and additionally as head of state from 1988. Ideologically, he initially adhered to Marxism–Leninism, but moved towards social democracy by the early 1990s.

Born in Privolnoye, North Caucasus Krai, into a peasant family of Russian and Ukrainian heritage, Gorbachev grew up under the rule of Joseph Stalin. In his youth, Gorbachev operated combine harvesters on a collective farm, before joining the Communist Party, which then governed the Soviet Union as a one-party state. Studying at Moscow State University, he married fellow student Raisa Titarenko in 1953 and received his law degree in 1955. Moving to Stavropol, he worked for the Komsomol youth organization and, after Stalin's death, became a keen proponent of the de-Stalinization reforms of Soviet leader Nikita Khrushchev.

Stalinism is the means of governing and Marxist–Leninist policies implemented in the Soviet Union (USSR) from 1927 to 1953 by Joseph Stalin. It included the creation of a one-party totalitarian police state, rapid industrialization, the theory of socialism in one country (until 1939), collectivization of agriculture, intensification of class conflict, a cult of personality, and subordination of the interests of foreign communist parties to those of the Communist Party of the Soviet Union, deemed by Stalinism to be the leading vanguard party of communist revolution at the time. After Stalin's death and the Khrushchev Thaw, a period of de-Stalinization began in the 1950s and 1960s, which caused the influence of Stalin's ideology to begin to wane in the USSR.

Stalin's regime forcibly purged society of what it saw as threats to itself and its brand of communism (so-called "enemies of the people"), which included political dissidents, non-Soviet nationalists, the bourgeoisie, better-off peasants ("kulaks"), and those of the working class who demonstrated "counter-revolutionary" sympathies. This resulted in mass repression of such people and their families, including mass arrests, show trials, executions, and imprisonment in forced labour camps known as gulags. The most notorious examples were the Great Purge and the Dekulakization campaign. Stalinism was also marked by militant atheism, mass anti-religious persecution, and ethnic cleansing through forced deportations. However, there was a short era of reconciliation between the Orthodox Church and the state authorities in WW2. Some historians, such as Robert Service, have blamed Stalinist policies, particularly the collectivization policies, for causing famines such as the Holodomor. Other historians and scholars disagree on the role of Stalinism.

Before the perestroika reforms of Mikhail Gorbachev that promoted a more liberal form of socialism, the formal ideology of the Communist Party of the Soviet Union (CPSU) was Marxism–Leninism, a form of socialism consisting of a centralised command economy with a vanguardist one-party state that aimed to realize the dictatorship of the proletariat. The Soviet Union's ideological commitment to achieving communism included the national communist development of socialism in one country and peaceful coexistence with capitalist countries while engaging in anti-imperialism to defend the international proletariat, combat the predominant prevailing global system of capitalism and promote the goals of Bolshevism. The state ideology of the Soviet Union – and thus Marxism–Leninism – derived and developed from the theories, policies, and political praxis of Karl Marx, Friedrich Engels, Vladimir Lenin, and Joseph Stalin.

A dictatorship is a form of government which is characterized by a leader who holds absolute or near-absolute political power. Politics in a dictatorship are controlled by a dictator, and they are facilitated through an inner circle of elites that includes advisers, generals, and other high-ranking officials. The dictator maintains control by influencing and appeasing the inner circle and repressing any opposition, which may include rival political parties, armed resistance, or disloyal members of the dictator's inner circle. Dictatorships can be formed by a military coup that overthrows the previous government through force or they can be formed by a self-coup in which elected leaders make their rule permanent. Dictatorships are authoritarian or totalitarian, and they can be classified as military dictatorships, one-party dictatorships, and personalist dictatorships.

The Latin word dictator originated in the early Roman Republic to refer to a constitutional office with "a temporary grant of absolute power to a leader to handle some emergency." Modern dictatorships first developed in the 19th century, which included Bonapartism in Europe and caudillos in Latin America. With the advent of the 19th and 20th centuries, dictatorships and constitutional democracies emerged as the world's two major forms of government, gradually eliminating monarchies, one of the traditional widespread forms of government of the time. Typically, a common aspect that characterizes dictatorship is suppressing freedom of thought and speech of the masses, in order to maintain complete political and social supremacy and stability. Dictatorships generally employ political propaganda to decrease the influence of proponents of alternative governing systems. The 20th century saw the rise of fascist and communist dictatorships in Europe; fascism was largely eradicated in the aftermath of World War II in 1945, while communism spread to other continents, maintaining prominence until the end of the Cold War in 1991. The 20th century also saw the rise of personalist dictatorships in Africa and military dictatorships in Latin America, both of which became prominent in the 1960s and 1970s.

Benito Amilcare Andrea Mussolini (29 July 1883 – 28 April 1945) was an Italian politician and journalist who was the dictator of Italy during the Fascist era from the March on Rome in 1922 until his overthrow in 1943. He founded the National Fascist Party (PNF) and served as Prime Minister of Italy from 1922, later adopting the title Duce ("leader") of Italian fascism. Mussolini first organized the Italian Fasces of Combat in 1919, which evolved into the PNF that established a totalitarian regime. As the founder of fascism, Mussolini was a key inspiration and contributor to the rise of similar movements across Europe during the interwar period.

Mussolini was originally a socialist politician and journalist at the Avanti! newspaper. In 1912, he became a member of the National Directorate of the Italian Socialist Party (PSI), but was expelled for advocating military intervention in World War I. In 1914, Mussolini founded a newspaper, Il Popolo d'Italia, and served in the Royal Italian Army until he was wounded and discharged in 1917. He eventually denounced the PSI, his views pivoting to focus on Italian nationalism, and founded the fascist movement which opposed egalitarianism and class conflict, instead advocating "revolutionary nationalism" transcending class lines. In October 1922, following the March on Rome, he was appointed prime minister by King Victor Emmanuel III. After removing opposition through his secret police and outlawing labour strikes, Mussolini and his followers consolidated power through laws that transformed the nation into a one-party dictatorship. Within five years, he established dictatorial authority by legal and illegal means and aspired to create a totalitarian state. In 1929, he signed the Lateran Treaty to establish Vatican City.

A cult of personality, or a cult of the leader, is the result of an effort to create an idealized and heroic image of an admirable leader, often through unquestioning flattery and praise.

Historically, it has been developed through techniques such as the manipulation of the mass media, the dissemination of propaganda, the staging of spectacles, the manipulation of the arts, the instilling of patriotism, and government-organized demonstrations and rallies. A cult of personality is similar to apotheosis (deification), except that it is established through the use of modern social engineering techniques, it is usually established by the state or the party in one-party states and dominant-party states. Cults of personality often accompany the leaders of totalitarian or authoritarian governments. They can also be seen in some monarchies, theocracies, failed democracies, and even in liberal democracies.
