The Communist Party of China (CPC), commonly known as the Chinese Communist Party (CCP), is the founding and sole governing party of the People's Republic of China (PRC). Founded in 1921, the CCP won the Chinese Civil War against the Kuomintang and proclaimed the establishment of the PRC under the chairmanship of Mao Zedong in October 1949. The CCP has since governed China and has had absolute control over the country's armed forces and law enforcement. As of 2025, the CCP has more than 101 million members, making it the second largest political party by membership in the world.
In 1921, Chen Duxiu and Li Dazhao founded the CCP with the help of the Far Eastern Bureau of the Russian Communist Party (Bolsheviks) and Far Eastern Bureau of the Communist International. Although the CCP aligned with the Kuomintang (KMT) during its initial years, the rise of the KMT's right-wing under the leadership of Chiang Kai-shek and subsequent massacres of tens of thousands of CCP members resulted in a split and a prolonged civil war between the CCP and KMT. During the next ten years of guerrilla warfare, Mao Zedong rose to become the most influential figure in the CCP and the party established a strong base among the rural peasantry with its land reform policies. Support for the CCP continued to grow throughout the Second Sino-Japanese War. After the Japanese surrender in 1945, the CCP emerged triumphant in the communist revolution against the Nationalist government. The CCP established the People's Republic of China on 1 October 1949, and the remnants of the Nationalist government retreated to Taiwan shortly after.
Mao Zedong remained the most influential member of the CCP until his death in 1976. Under Mao, the party completed its land reform program, launched a series of five-year plans, and eventually split with the Soviet Union. Although Mao attempted to purge the party of elements deemed capitalist or reactionary during the Cultural Revolution, these policies were only briefly continued by the Gang of Four following his death before a less radical faction seized control. During the 1980s, Deng Xiaoping directed the CCP away from Maoist orthodoxy and towards reform and opening up. Since the collapse of the Eastern Bloc and the dissolution of the Soviet Union in 1991, the CCP has focused on maintaining its relations with the governing parties of the remaining communist states. The CCP has also established relations with several non-communist parties, including dominant nationalist parties of many developing countries in Africa, Asia, and Latin America, as well as social democratic parties in Europe.
As a communist party, the CCP officially seeks to adapt Marxism–Leninism to Chinese material conditions and present-day circumstances, a process it refers to as socialism with Chinese characteristics. The party is organized based on democratic centralism, a principle that entails open policy discussion on the condition of unity among party members in upholding the agreed-upon decision. The highest body of the CCP is the National Congress, convened every five years. When the National Congress is not in session, the Central Committee is the highest body, but since that body usually only meets once a year, most duties and responsibilities are vested in the Politburo and its Standing Committee. Members of the latter are regarded as the party's and the state's top leadership.
Today the party's leader holds the offices of general secretary (responsible for civilian party duties, also the top rank official), chairman of the Central Military Commission (CMC) (commander-in-chief of the military), and president of China (a largely ceremonial position). Because of these posts, the party leader is seen as the country's "paramount leader". The current leader is Xi Jinping, who was elected at the 1st Plenary Session of the 18th Central Committee held on 15 November 2012 and has been reelected twice, on 25 October 2017 by the 19th Central Committee and on 10 October 2022 by the 20th Central Committee.
History
Founding and early history
The October Revolution and Marxist theory inspired the founding of the CCP. Chen Duxiu and Li Dazhao were among the first to publicly support Leninism and world revolution. Both regarded the October Revolution in Russia as groundbreaking, believing it to herald a new era for oppressed countries everywhere.
Some historical analysis views the May Fourth Movement as the beginning of the revolutionary struggle that led to the founding of the People's Republic of China. Following the movement, trends towards social transformation increased. Writing in 1939, Mao Zedong stated that the Movement had shown that the bourgeois revolution against imperialism and China had developed to a new stage, but that the proletariat would lead the revolution's completion. The May Fourth Movement led to the establishment of radical intellectuals who went on to mobilize peasants and workers into the CCP and gain the organizational strength that would solidify the success of the Chinese Communist Revolution. Chen and Li were among the most influential promoters of Marxism in China during the May Fourth period. The CCP itself embraces the May Fourth Movement and views itself as part of the movement's legacy.
Study circles were, according to Cai Hesen, "the rudiments [of our party]". Several study circles were established during the New Culture Movement, but by 1920 many grew sceptical about their ability to bring about reforms. China's intellectual movements were fragmented in the early 1920s. The May Fourth Movement and the New Culture Movement had identified issues of broad concern to Chinese progressives, including anti-imperialism, support for nationalism, support for democracy, promotion of feminism, and rejection of traditional values. Proposed solutions among Chinese progressives differed significantly, however.
The CCP's founding congress commenced on 23 July 1921. At the time, there were 57 members of the CCP and 13 Chinese delegates present at the founding. While it was originally held in a house in the Shanghai French Concession, French police interrupted the meeting on 30 July and the congress was moved to a tourist boat on South Lake in Jiaxing, Zhejiang province. Neither Li Dazhao nor Chen Duxiu attended, the latter sending a personal representative in his stead. The resolutions of the congress called for the establishment of a communist party as a branch of the Communist International (Comintern) and elected Chen as its leader. Chen then served as the first general secretary of the CCP.
The Soviets hoped to foster pro-Soviet forces in East Asia to fight against anti-communist countries, particularly Japan. They attempted to contact the warlord Wu Peifu but failed. The Soviets then contacted the Kuomintang (KMT), which was leading the Guangzhou government parallel to the Beiyang government. On 6 October 1923, the Comintern sent Mikhail Borodin to Guangzhou, and the Soviets established friendly relations with the KMT. The Central Committee of the CCP, Soviet leader Joseph Stalin, and the Comintern all hoped that the CCP would eventually control the KMT and called their opponents "rightists". KMT leader Sun Yat-sen eased the conflict between the communists and their opponents. CCP membership grew tremendously after the 4th congress in 1925, from 900 to 2,428. The CCP still treats Sun Yat-sen as one of the founders of their movement and claim descent from him as he is viewed as a proto-communist and the economic element of Sun's ideology was socialism. Sun stated, "Our Principle of Livelihood is a form of communism".
The communists dominated the left wing of the KMT and struggled for power with the party's right-wing factions. When Sun Yat-sen died in March 1925, he was succeeded by a rightist, Chiang Kai-shek, who initiated moves to marginalize the position of the communists. Chiang, Sun's former assistant, was not actively anti-communist at that time, even though he hated the theory of class struggle and the CCP's seizure of power. The communists proposed removing Chiang's power. When Chiang gradually gained the support of Western countries, the conflict between him and the communists became more and more intense. Chiang asked the Kuomintang to join the Comintern to rule out the secret expansion of communists within the KMT, while Chen Duxiu hoped that the communists would completely withdraw from the KMT.
In April 1927, both Chiang and the CCP were preparing for conflict. Fresh from the success of the Northern Expedition to overthrow the warlords, Chiang Kai-shek turned on the communists, who by now numbered in the tens of thousands across China. Ignoring the orders of the Wuhan-based KMT government, he marched on Shanghai, a city controlled by communist militias. Although the communists welcomed Chiang's arrival, he turned on them, massacring 5,000 with the aid of the Green Gang. Chiang's army then marched on Wuhan but was prevented from taking the city by CCP General Ye Ting and his troops. Chiang's allies also attacked communists; for example, in Beijing, Li Dazhao and 19 other leading communists were executed by Zhang Zuolin. Angered by these events, the peasant movement supported by the CCP became more violent. Ye Dehui, a famous scholar, was killed by communists in Changsha, and in revenge, KMT general He Jian and his troops gunned down hundreds of peasant militiamen. That May, tens of thousands of communists and their sympathizers were killed by KMT troops, with the CCP losing approximately 15,000 of its 25,000 members.
Chinese Civil War and Second Sino-Japanese War
The CCP continued supporting the Wuhan KMT government, but on 15 July 1927 the Wuhan government expelled all communists from the KMT. The CCP reacted by founding the Workers' and Peasants' Red Army of China, better known as the "Red Army", to battle the KMT. A battalion led by General Zhu De was ordered to take the city of Nanchang on 1 August 1927 in what became known as the Nanchang uprising.
Initially successful, Zhu and his troops were forced to retreat after five days, marching south to Shantou, and from there being driven into the wilderness of Fujian. Mao Zedong was appointed commander-in-chief of the Red Army, and led four regiments against Changsha in the Autumn Harvest Uprising, hoping to spark peasant uprisings across Hunan. His plan was to attack the KMT-held city from three directions on 9 September, but the Fourth Regiment deserted to the KMT cause, attacking the Third Regiment. Mao's army made it to Changsha but could not take it; by 15 September, he accepted defeat, with 1,000 survivors marching east to the Jinggang Mountains of Jiangxi.
The near destruction of the CCP's urban organizational apparatus led to institutional changes within the party. The party adopted democratic centralism, a way to organize revolutionary parties, and established a politburo to function as the standing committee of the central committee. The result was increased centralization of power within the party. At every level of the party this was duplicated, with standing committees now in effective control. The 1929 Gutian Congress was important in establishing the principle of party control over the military, which continues to be a core principle of the party's ideology. After being expelled from the party, Chen Duxiu went on to lead China's Trotskyist movement. Li Lisan was able to assume de facto control of the party organization by 1929–1930.
Li's leadership was a failure, leaving the CCP on the brink of destruction. The Comintern became involved, and by late 1930, his powers had been taken away. By 1935, Mao had become a member of Politburo Standing Committee of the CCP and the party's informal military leader, with Zhou Enlai and Zhang Wentian, the formal head of the party, serving as his informal deputies. The conflict with the KMT led to the reorganization of the Red Army, with power now centralized in the leadership through the creation of CCP political departments charged with supervising the army.
The Xi'an Incident of December 1936 paused the conflict between the CCP and the KMT. Under pressure from Marshal Zhang Xueliang and the CCP, Chiang Kai-shek finally agreed to a Second United Front focused on repelling the Japanese invaders. While the front formally existed until 1945, all collaboration between the two parties had effectively ended by 1940. Despite their formal alliance, the CCP used the opportunity to expand and carve out independent bases of operations to prepare for the coming war with the KMT. In 1939, the KMT began to restrict CCP expansion within China. This led to frequent clashes between CCP and KMT forces which subsided rapidly on the realization on both sides that civil war amidst a foreign invasion was not an option. By 1943, the CCP was again actively expanding its territory at the expense of the KMT.
Mao Zedong became the Chairman of the Politburo in 1943 and the Chairman of the Central Committee in 1945. After the Japanese surrender in 1945, the war between the CCP and the KMT began again in earnest. The 1945–1949 period had four stages; the first was from August 1945 (when the Japanese surrendered) to June 1946 (when the peace talks between the CCP and the KMT ended). By 1945, the KMT had three times more soldiers under its command than the CCP and initially appeared to be prevailing. With the cooperation of the US and Japan, the KMT was able to retake major parts of the country. However, KMT administration of the territories proved unpopular because of its endemic political corruption.
Notwithstanding its numerical superiority, the KMT failed to reconquer the rural territories which made up the CCP's stronghold. Around the same time, the CCP launched an invasion of Manchuria, where they were assisted by the Soviet Union. The second stage, lasting from July 1946 to June 1947, saw the KMT extend its control over major cities such as Yan'an, the CCP headquarters, for much of the war. The KMT's successes were hollow; the CCP had tactically withdrawn from the cities, and instead undermined the KMT there by instigating protests among students and intellectuals. The KMT responded to these demonstrations with heavy-handed repression. In the meantime, the KMT was struggling with factional infighting and Chiang Kai-shek's autocratic control over the party, which weakened its ability to respond to attacks.
The third stage, lasting from July 1947 to August 1948, saw a limited counteroffensive by the CCP. The objective was clearing "Central China, strengthening North China, and recovering Northeast China." This operation, coupled with military desertions from the KMT, resulted in the KMT losing 2 million of its 3 million troops by the spring of 1948, and saw a significant decline in support for the KMT. The CCP was consequently able to cut off KMT garrisons in Manchuria and retake several territories.
The last stage, lasting from September 1948 to December 1949, saw the communists go on the offensive and the collapse of KMT rule in mainland China as a whole. Mao's proclamation of the founding of the People's Republic of China on 1 October 1949 marked the end of the second phase of the Chinese Civil War (or the Chinese Communist Revolution, as it is called by the CCP).
Proclamation of the PRC and the Mao era
Mao proclaimed the founding of the People's Republic of China (PRC) before a massive crowd at Tiananmen Square on 1 October 1949. The CCP headed the Central People's Government. From this time through the 1980s, top leaders of the CCP (such as Mao Zedong, Lin Biao, Zhou Enlai and Deng Xiaoping) were largely the same military leaders prior to the PRC's founding. As a result, informal personal ties between political and military leaders dominated civil-military relations.
