Party leader in the context of "Party chair"

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.

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.

The chairman of the Central Committee of the Chinese Communist Party (Chinese: 中国共产党中央委员会主席; pinyin: Zhōngguó Gòngchǎndǎng Zhōngyāng Wěiyuánhuì Zhǔxí) was the leader of the Chinese Communist Party. The position was established at the 8th National Congress in 1945 and abolished at the 12th National Congress in 1982, being replaced by the general secretary. Offices with the name Chairman of the Central Executive Committee and Chairman of the Central Committee existed in 1922–1923 and 1928–1931, respectively.

The premier of China, officially the Premier of the State Council of the People's Republic of China, is the head of government of the People's Republic of China (PRC) and leader of the State Council. The post of prime minister was established in 1911 near the end of the Qing dynasty, but the current post dates to 1954, five years after the establishment of the PRC. The premier is the third-highest ranking official in China's political system after the general secretary of the Chinese Communist Party (party leader) and the president (state representative), and holds the highest rank in the civil service of the central government.

The premier presides over the plenary and executive meetings of the State Council, and assumes overall leadership over the State Council's work. The premier delivers a government work report at the annual session of the NPC. The premier also signs administrative regulations passed by the State Council and signs the orders approving the appointment and removal of deputy-ministerial level officials of the State Council, as well as chief executives of Hong Kong and of Macau. The premier additionally has the authority to impose martial law. The premier is assisted by four vice premiers and state councillors in their duties. The premier heads the Leading Party Members Group of the State Council. In China's political system, the premier has generally thought to be the one responsible for managing the economy.

Primary elections or primaries are elections held to determine which candidates will run in an upcoming general election. In a partisan primary, a political party selects a candidate. Depending on the state and/or party, there may be an "open primary", in which all voters are eligible to participate, or a "closed primary", in which only members of a political party can vote. Less common are nonpartisan primaries in which all candidates run regardless of party.

The origins of primary elections can be traced to the progressive movement in the United States, which aimed to take the power of candidate nomination from party leaders to the people. However, political parties control the method of nomination of candidates for office in the name of the party. Other methods of selecting candidates include caucuses, internal selection by a party body such as a convention or party congress, direct nomination by the party leader, and nomination meetings.

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.
