Mao Zedong's Communist Party won China's long civil war and proclaimed the People's Republic of China on October 1, 1949.
See it on the History map →What happened
The Communists and Chiang Kai-shek's Nationalists (Kuomintang) fought from 1927, partly paused to resist Japan's invasion from 1937, then resumed full war in 1946. The Communists won peasants over with land reform and fought a guerrilla war; the Nationalists were drained by war, inflation and corruption. Mao proclaimed the People's Republic in Beijing, and Chiang retreated to Taiwan, where the Republic of China survives. Land reform afterward killed an estimated one to two million landlords and others; estimates vary.
Why it matters
It put the world's most populous country under Communist rule, made the Cold War truly global, and left the China–Taiwan split that persists today.
How we know
Communist and Nationalist records, US diplomatic cables, reporting such as Edgar Snow's Red Star Over China, and memoirs. Many Chinese archives remain restricted.
Still debated
Whether Japan's invasion, which exhausted the Nationalists, or Communist strategy did more to decide the outcome is debated.

Connections (5)
▸Qing dynasty collapsed in 1912, starting the turmoil behind the Chinese Communist RevolutionWell documented
The connection
The Qing, weakened by foreign defeats and the Taiping war, fell in the 1911 revolution, and the last emperor abdicated in 1912. The new republic broke apart among warlords. In that chaos the Nationalist Party and the Communist Party, founded 1921, competed to reunify China, leading to the civil war the Communists won in 1949.
When and how
Wuchang uprising, October 1911; abdication of the six-year-old emperor Puyi, February 1912; warlord era about 1916–1928.
How we know
The abdication edict, republican records and both parties' own histories document the sequence; historians agree the collapse opened decades of upheaval.
Debates and open questions
Whether a stable republic could have emerged without Japan's invasion, and how far the Qing's late reforms might have gone, are debated.
▸Marx and the Communist Manifesto inspired the Chinese Communist RevolutionWell documented
The connection
Marx's ideas reached China after Russia's 1917 revolution, and the Chinese Communist Party was founded in 1921 with Soviet help. Marxism expected factory workers to lead revolution; Mao adapted it to a peasant country, making rural farmers the revolutionary force. The Party still names Marxism-Leninism and Mao Zedong Thought as its guiding ideology.
When and how
Chen Wangdao's Chinese translation of the Manifesto appeared in 1920; the Party's founding congress met in Shanghai in July 1921.
How we know
Party documents, Mao's writings and the Party constitution cite Marx directly; Comintern (Soviet-led international) archives show the role of Soviet advisers.
Debates and open questions
How Marxist Mao really was, versus a nationalist and peasant rebel using Marxist language, has long been debated.
▸Opium Wars began China's 'century of humiliation' before the Chinese Communist RevolutionDebated
The connection
Britain's victories in the Opium Wars forced China to open ports, cede Hong Kong and accept 'unequal treaties'. Defeats by France, Japan and others followed. The Communist Party built its story around ending this 'century of humiliation', 1839 to 1949, and presented its 1949 victory as the moment China 'stood up'.
When and how
First Opium War 1839–42 and the Treaty of Nanjing, 1842; 'national humiliation' became a rallying cry from 1915, used by Nationalists and later Communists.
How sure are we?
The wars and treaties are well documented. The link is debated because the 'century of humiliation' is partly a political narrative built later by both parties.
Debates and open questions
Historians debate how much foreign pressure, versus internal problems like population growth, rebellion and weak government, caused the Qing decline.
▸Chinese Communist Revolution created the regime that intervened in the Korean WarWell documented
The connection
Barely a year after taking power, Mao's new People's Republic sent troops, officially 'volunteers', across the Yalu River in October 1950 as UN forces neared its border. They drove the UN back south of Seoul. China's intervention turned the war into a stalemate and made China and the US enemies for two decades.
When and how
From October 1950; commander Peng Dehuai led hundreds of thousands of troops at a time. Mao's own son was killed in a US air raid.
How we know
Chinese, Soviet and US archives document the decision, argued over in Beijing for days. Chinese deaths are estimated at about 180,000 to 400,000; estimates vary.
Debates and open questions
Whether Mao intervened mainly for security, ideology or under pressure from Stalin, and whether UN forces could have avoided it by stopping short, is debated.
▸Chinese Communist Revolution led to Mao's Great Leap Forward and Cultural RevolutionWell documented
The connection
Victory gave Mao and the Party total control of China. First copying the Soviet model, then trying to outrun it, Mao launched the Great Leap Forward in 1958, aiming to overtake Britain's steel output within 15 years. Later, fearing rivals and fading revolutionary zeal, he started the Cultural Revolution in 1966.
When and how
China, 1958–1962 and 1966–1976; defense minister Peng Dehuai was purged in 1959 for criticizing the Leap.
How we know
Party documents, and the Party's own 1981 resolution blaming Mao for the Cultural Revolution, tie the campaigns to his revolutionary aims.
Debates and open questions
How much the disasters came from Mao personally, versus the one-party system the revolution built or other leaders, is debated.
