General Secretary of the Communist Party in the context of "Tsar Bomba"

Secretary is a title often used in organizations to indicate a person having a certain amount of authority, power, or importance in the organization. Secretaries announce important events and communicate to the organization. The term is derived from the Latin word secernere, "to distinguish" or "to set apart", the passive participle (secretum) meaning "having been set apart", with the eventual connotation of something private or confidential, as with the English word secret. A secretarius was a person, therefore, overseeing business confidentially, usually for a powerful individual (a king, pope, etc.).

The official title of the leader of most communist and socialist political parties is the "General Secretary of the Central Committee" or "First Secretary of the Central Committee". When a communist party is in power, the general secretary is usually the country's de facto leader (though sometimes this leader also holds state-level positions to monopolize power, such as a presidency or premiership in order to constitute de jure leadership of the state), such as China, North Korea, Vietnam, Laos and Cuba.

Bolesław Bierut ([bɔˈlɛswaf ˈbʲɛrut] ; 18 April 1892 – 12 March 1956) was a Polish communist activist and politician, leader of communist-ruled Poland from 1948 until 1956. He was President of the State National Council from 1944 to 1947, President of Poland from 1947 to 1952, General Secretary of the Central Committee of the Polish United Workers' Party from 1948 to 1956, and Prime Minister of Poland from 1952 to 1954. Bierut is believed to have worked as an NKVD informant or agent prior to 1945, although his relationship with the Soviet agency has been a subject of debate among historians. As communist leader, he implemented aspects of the Stalinist system in Poland. Together with Władysław Gomułka, his main rival, Bierut is chiefly responsible for the historic changes that Poland underwent in the aftermath of World War II. Unlike any of his communist successors, Bierut led Poland until his death.

Born in Congress Poland on the outskirts of Lublin, Bierut joined the Polish Socialist Party in 1912. Later he became a member of the Communist Party of Poland and spent some years in the Soviet Union. He was sentenced to a prison term in 1935 for conducting illegal labor activity in Poland by the anti-communist Sanation government and was later released in 1938. During World War II, Bierut was an activist of the newly founded Polish Workers' Party (PPR) and subsequently the chairman of the State National Council (KRN), established by the PPR. Trusted by Joseph Stalin, Bierut participated in the Potsdam Conference, where he successfully lobbied for the establishment of Poland's western border at the Oder–Neisse line.

The general secretary of the Communist Party of Vietnam Central Committee (Vietnamese: Tổng Bí thư Ban Chấp hành Trung ương Đảng Cộng sản Việt Nam), simply and informally the party general secretary or just general secretary (Tổng bí thư, TBT), is the contemporary title for the holder of the highest office within the Communist Party of Vietnam (CPV), being in practice the highest position in the politics of Vietnam and is considered one of the four pillars of the country's leadership. The general secretaryship used to be the second-highest office within the party when Hồ Chí Minh was the chairman, a post which existed from 1951 to 1969, and since 1969, the general secretary has generally been regarded as the highest leader of Vietnam. The general secretary also holds the title of secretary of the Central Military Commission, the leading party organ on military affairs, being the highest political and ideological leader of the People's Army of Vietnam; however, unlike other Communist Parties' leaders, the Vietnamese position rarely assumes a co-official government office or title such as State President at the same time, alongside the consensus-based four pillars slightly lowering the position's supremacy in the Vietnamese political system to its one-party counterparts. The current general secretary is Tô Lâm, ranking first in the Politburo. The position was once designated the first secretary (Vietnamese: Bí thư Thứ nhất) from 1951 to 1976.

Trần Phú, one of the founding members of the Indochinese Communist Party, was the party's first general secretary. A year after being elected, he was sentenced to prison by the French authorities because of anti-French activities. He died in prison the same year. Trần's de facto successor was Lê Hồng Phong who led the party through the office of General Secretary of the Overseas Executive Committee (OEC). The OEC general secretary led the party because the Central Committee had been all but annihilated. Hà Huy Tập, the third general secretary, was removed from his post in March 1938, and was arrested by the authorities in May. Nguyễn Văn Cừ, the fourth general secretary, was arrested by the authorities in January 1940, and executed by shooting on 28 August 1941. He was succeeded by Trường Chinh. An article in Nhân Dân on 25 March 1951 described Trường Chinh's role as the "builder and commander" of the revolution, while Hồ Chí Minh was referred to as "the soul of the Vietnamese revolution and the Vietnamese resistance". Trường Chinh was demoted as first secretary in 1956 because of his role in the Land Reform campaign". Hồ Chí Minh took over the office of first secretary, but quickly appointed Lê Duẩn acting first secretary. Lê Duẩn was elected first secretary in 1960 and was second only to Hồ Chí Minh until the latter's death on 2 September 1969.

A central committee is a political-executive organ designated as the highest organ of a communist party between two congresses. Per the principles of democratic centralism, a central committee is empowered to deal with any issue that falls under the party's purview. While formally retaining this role in socialist states, commonly referred to as communist states by outside observers, in practice, it delegates this authority to numerous smaller internal organs due to the infrequency of its meetings.

The term of a central committee of a ruling communist party is usually five years. The party congress elects individuals to the central committee and holds it accountable. At the first central committee session held immediately after a congress, it elects the party leader, an office usually titled general secretary of the central committee, a political organ, commonly known as the politburo, and an executive organ, customarily named the secretariat.

The First Secretary of the Central Committee of the Communist Party of Cuba is the top leader of Cuba. The first secretary is the highest office within the Communist Party of Cuba, which makes the officeholder the most powerful person in the Cuban party-state. In communist states the first or general secretary of a ruling communist party is typically the de facto leader of the country and a more powerful position than state offices such as President (head of state) or Prime Minister (head of government), when different individuals hold those positions.

The officeholder of the post of first secretary presides over the work of the Central Committee of the Communist Party of Cuba (PCC), which is designated as "the organised vanguard of the Cuban nation" and as "the superior driving force of society and the State" by Article 5 of Cuba's constitution. The PCC Central Committee, the Party's highest political-executive organ between convocations of the party congress, has the right to elect and dismiss the first secretary at one of its sessions. The first secretary is responsible for leading the work of the Secretariat, the Party's highest executive organ, and chairing the sessions of the Politburo, the Party's highest political organ. The current first secretary is Miguel Díaz-Canel, elected by the 1st Session of the 8th Central Committee on 19 April 2021, and he concurrently serves as president of Cuba.

Hafizullah Amin (Dari/Pashto: حفيظ الله امين;‎ 1 August 1929 – 27 December 1979) was an Afghan communist head of state, who served in that position for a little over three months, from September 1979 until his assassination. He organized the Saur Revolution of 1978 and co-founded the Democratic Republic of Afghanistan (DRA), ruling Afghanistan as General Secretary of the People's Democratic Party.

Born in the town of Paghman in Kabul Province, Amin studied at Kabul University and started his career as a teacher before he twice went to the United States to study. During this time, Amin became attracted to Marxism and became involved in radical student movements at the University of Wisconsin. Upon his return to Afghanistan, he used his teaching position to spread socialist ideologies to students, and he later joined the People's Democratic Party of Afghanistan (PDPA), a new far-left organization co-founded by Nur Muhammad Taraki and Babrak Karmal. He ran as a candidate in the 1965 parliamentary election but failed to secure a seat, but in 1969 became the only Khalqist elected to parliament, increasing his standing within the party.
