How Are Leaders Chosen in Communism: Congress and Nomenklatura

Leaders in communism are chosen by the Communist Party itself, through an internal, multi-tiered process that runs entirely inside the party apparatus. There is no open public election for the top job. Party members elect delegates to a National Congress, that congress elects a Central Committee of several hundred people, and the Central Committee then elects the Politburo, its Standing Committee, and the General Secretary who effectively runs the country. Every step is shaped by candidates pre-approved by the leadership already in place.

Only the Party Can Produce a Leader

In every communist state, the Communist Party is the sole legitimate political organization. There is no opposition party, no independent candidacy, and no route to national office that bypasses party membership. The party’s structure reaches from neighborhood cells up through district, regional, and national bodies, and that pipeline is what filters who can advance.

This is written into the founding documents. The Constitution of the Communist Party of China states that the party “is an integral body organized under its own program and Constitution and on the basis of democratic centralism,” with all members and lower organizations deferring to the National Congress and Central Committee.¹ Government posts, military commands, judicial seats, and state media leadership are filled by people the party has cleared. Someone outside the party has no realistic chance of holding meaningful power.

Democratic Centralism Sets the Rules

The governing principle behind every communist selection process is “democratic centralism,” a concept Vladimir Lenin developed in the early 1900s. The idea sounds balanced. Members debate a question freely, but once a majority decides, everyone carries out the decision without further dissent. Lenin described it as “universal and full freedom to criticise, so long as this does not disturb the unity of a definite action.”

In practice, the balance tilts hard toward the centralism side. The CPC Constitution spells out the chain: individual members defer to party organizations, minorities defer to majorities, lower bodies defer to higher bodies, and everything defers to the National Congress and Central Committee.¹ Higher bodies control the agenda, frame the debate, and propose the candidates. Members who keep arguing against a settled decision can face sanctions up to expulsion.

So when the party holds an “election,” the debate has usually already happened at a level above the voters, and the vote itself confirms a choice that has been shaped in advance.

The Tiered Congress Vote

Formally, communist parties elect their leaders through a stack of congresses. Members in local cells vote for delegates to district or regional conferences. Those conferences elect delegates to higher-level meetings, and so on up to the National Congress, the party’s supreme decision-making body.

At the National Congress, delegates elect the Central Committee, which then meets in a first plenary session and elects the Politburo, the Politburo Standing Committee, and the General Secretary. The CPC Constitution says elections of delegates and committee members at every level “shall reflect the will of the voters” and “shall be held by secret ballot.”¹

What the constitution doesn’t say is that the candidates on the ballot are typically vetted and slated by leadership committees before any vote occurs. Delegates vote on a pre-approved list rather than choosing from an open field. Floor nominations are theoretically possible but almost never succeed. At the CPC’s 20th National Congress in 2022, the newly elected Central Committee held its first plenary session and elected Xi Jinping as General Secretary along with the Politburo Standing Committee.² The formation of that leadership involved extensive deliberation and consultation before the plenary session ratified the results.³

The Nomenklatura Fills Every Position Below the Top

The congress vote is only half the machinery. The other half is the nomenklatura, a system the Soviet Communist Party built and other communist states adopted in their own forms. It is a list of positions the party considers politically significant, paired with a list of people the party has judged reliable enough to fill them. Every appointment on that list requires party approval.

In China, the Organization Department of the CPC Central Committee runs this function. It keeps files on cadres throughout the system, tracks their performance, evaluates their political reliability, and controls promotions. A provincial governor, a university president, a military commander, and a state media editor all sit in positions covered by the system. None can be appointed without the Organization Department’s involvement.

Evaluation goes well past job performance. Officials are judged on ideological loyalty, willingness to hold the party line, and personal conduct. The CPC runs periodic “governance and performance appraisals” for officials from the county level up, watching for deviation from the correct line and behavior like forming internal cliques. Major appointments are made “through discussion by the Party committee concerned in accordance with the principles of collective leadership, democratic centralism, pre-meeting contemplation, and meeting-based decision making.”¹

The practical effect is that ambitious officials spend their careers cultivating relationships with the people doing the evaluating. That is where patronage networks and factions form, and it is where real influence over future leadership selection lives.

The Climb Takes Decades

Reaching the top of a communist system is rarely quick. A future General Secretary usually begins in a local party committee, moves through district and provincial roles, and only reaches national bodies after many years. Along the way they build alliances, demonstrate ideological reliability, and prove they can govern without creating problems for superiors.

Competence alone is not enough. Factional loyalty matters. So does having a powerful patron who will push for your promotion at higher levels. In many cases, leaders are groomed for the top job years in advance and placed in progressively more visible roles to build their credentials.

The CPC Constitution formally prohibits “all forms of personality cult” and requires that “the activities of Party leaders are subject to oversight by the Party and the people.”¹ Personality cults have nevertheless emerged in nearly every communist state, from Stalin to Mao to the Kim family.

When the Formal Process Breaks Down

The tiered congress procedure suggests an orderly system. History repeatedly says otherwise. Communist leadership transitions have often involved purges, coups against sitting leaders, and backroom deals that don’t match anything in the party constitution.

After Lenin’s death in 1924, Joseph Stalin used his control of the Central Committee Secretariat to place allies in provincial committees, which gave him control over the delegations that voted at party congresses, which gave him the votes to defeat and eventually expel his rivals. By the late 1920s his personal power far exceeded anything the constitution contemplated. Khrushchev was later removed from power in 1964 by a Politburo vote arranged while he was on vacation.

China went through the Cultural Revolution in the 1960s and 1970s, when Mao Zedong used mass mobilization to purge rivals and bypass institutional channels entirely. After Mao’s death in 1976, the “Gang of Four” was arrested in what amounted to a palace coup. When real power is at stake, the formal mechanism gives way to whoever can command the security services and the military.

Even in calm periods, the important decisions about top leadership happen in informal consultations among sitting Politburo members and sometimes retired seniors, well before any formal vote. The congress vote ratifies a choice already made elsewhere.

How It Varies From Country to Country

Every communist state shares the single-party mechanism, but the details differ.

The Soviet Union

The original model. The Communist Party of the Soviet Union held a Party Congress every five years, where thousands of delegates selected a Central Committee, which in turn chose the Politburo and Secretariat. The General Secretary became the country’s most powerful figure, though the position carried no formal government title until Brezhnev also took the presidency. Succession was often chaotic because there was no clear rule for replacing a leader who died in office.

China

China adopted the Soviet model and modified it. After the Mao era, Deng Xiaoping introduced informal norms to make transitions more orderly, including an unofficial age guideline sometimes called “seven up, eight down,” meaning Politburo Standing Committee members aged 67 or younger could stay while those 68 or older were expected to retire. These norms never entered the constitution. Xi Jinping has moved away from them. In 2018, the National People’s Congress removed the two-term limit on the presidency, and Xi was elected to an unprecedented third term as General Secretary in 2022.²

Vietnam

Vietnam’s Communist Party runs on a consensus model in which internal factions negotiate Politburo composition before formal votes. The Politburo, currently 19 members, controls virtually every strategic appointment, from ministers to provincial party secretaries to military commanders. Vietnam has kept a norm of rotating top positions, though the deliberations behind the appointments are opaque to the public.

Cuba

Cuba’s Communist Party held power under Fidel Castro for nearly five decades, with leadership passing to his brother Raúl Castro in 2008 and then to Miguel Díaz-Canel in 2021. The transition to Díaz-Canel was the first time someone outside the Castro family led Cuba since the revolution, and the Communist Party congress managed the entire process internally.

North Korea

North Korea is the sharpest departure from communist orthodoxy on this question. Power has passed from Kim Il-sung to his son Kim Jong-il and then to his grandson Kim Jong-un. Traditional communist ideology denounced hereditary succession as feudal, but North Korean propaganda justifies it through the idea of “revolutionary lineage,” claiming revolutionary qualities pass from parent to child. The Workers’ Party of Korea formally ratifies each succession without playing any independent role in choosing it.

Collective Leadership and Strongman Rule

Communist theory promotes “collective leadership,” in which the General Secretary is described as first among equals within the Politburo and major decisions are reached by consensus. The CPC Constitution requires “combining collective leadership with individual responsibility based on the division of work.”¹ The principle is meant to keep any single leader from accumulating unchecked power.

Most communist states swing between collective leadership and strongman rule. Collective leadership tends to appear right after a dominant leader dies or is removed. It then erodes as one figure builds enough factional support to dominate the rest. China saw relatively collective leadership under Hu Jintao before shifting toward centralized personal authority under Xi Jinping.

The tools a rising leader uses to consolidate power are usually the same ones the party constitution provides for routine governance. Control over the Organization Department means control over appointments. Control over the discipline inspection system means the ability to investigate and remove rivals under an anti-corruption banner. Those levers, plus military loyalty, decide who actually holds power in a communist system, far more than any congress vote.
