Civil War and Communist Victory, 1945-49
A War of Two Halves
The Chinese Civil War of 1946–49 falls neatly into two phases. In the opening eighteen months, the Guomindang (GMD) seemed to be winning. Chiang Kai-shek’s armies pushed into communist territory, captured the CCP capital of Yan’an in March 1947 and dominated almost every major city. By the autumn of 1948, however, the picture had reversed. In just over a year, the People’s Liberation Army (PLA) destroyed the GMD field armies in three campaigns, marched into Beijing without a fight and forced Chiang to flee for Taiwan. To explain Mao’s victory, weigh leadership, military choices and the collapse of GMD legitimacy in the cities against each other — not military genius alone.
Three decisive 1948–49 campaigns ended the war: Liaoshen (Sept–Nov 1948, Manchuria), Huaihai (Nov 1948–Jan 1949, central China) and Pingjin (Nov 1948–Jan 1949, Beijing–Tianjin). Together they cost the GMD about 1.5 million troops.
CCP Strategy in the Countryside
From 1946, the CCP traded cities for countryside. Mao called it ‘luring the enemy in deep’. When GMD divisions advanced into communist zones, PLA units melted away, broke into smaller groups and harassed supply lines. The GMD seized empty towns; the PLA kept its soldiers and its peasant base. While Chiang’s armies thinned themselves out garrisoning captured cities, Lin Biao quietly built a powerful conventional force in Manchuria, supplied with captured Japanese weapons that the Soviets had passed to the CCP in 1945–46.
Behind the lines the party stepped up land reform. The Outline Land Law of October 1947 declared that all land would be redistributed equally; landlords were denounced in mass meetings and tens of thousands were killed. The reform was violent and not always popular — some ‘middle peasants’ lost out — but it bound the rural population to the CCP. Peasants who received land had a direct stake in the communist victory and were a steady source of recruits.
The CCP victory was multi-causal. Mao’s flexible strategy and the discipline of Lin Biao’s armies clearly mattered, but so did GMD self-destruction. Hyperinflation, corruption, brutal conscription and student protest in the cities meant Chiang lost the war in two places at once — on the battlefield and in the urban classroom and marketplace. Strong answers weigh CCP strengths against GMD failings rather than choosing one side of the equation.
The Guomindang Collapse in the Cities
While Mao consolidated the countryside, Chiang’s urban support disintegrated. By August 1948 the Chinese yuan had become worthless: a single US dollar bought 12 million yuan. The GMD launched the ‘gold yuan’ currency reform that month, ordering citizens to exchange gold and silver for new notes — the new notes also collapsed within weeks. Civil servants could no longer afford rice. University students protested against corruption and conscription, and were beaten by GMD police. American visitors who had been sympathetic to Chiang — including journalists and US Marshall Mission staff — began describing his regime as terminal.
The American government noticed. From mid-1948 the United States began winding down direct aid: the ‘China White Paper’ published by the State Department in August 1949 effectively wrote off the GMD. Madame Chiang Kai-shek (Soong Mei-ling) toured Washington begging for emergency funds, and was politely refused. The lesson to draw is that c.$3 billion in US aid had not bought political legitimacy — the problem was internal.
The Decisive Year, 1948
From September 1948, Lin Biao opened the Liaoshen Campaign. Within seven weeks, around 470,000 GMD troops were killed or captured and Manchuria fell. The PLA inherited Japanese-built arsenals, railways and 600,000 captured rifles. Four days later, on 6 November, the Huaihai Campaign opened in central China. Over two months, around 555,000 GMD soldiers were destroyed across a battlefield north of the Yangtze. By January 1949 the Pingjin Campaign closed the trap on Beijing — the GMD garrison surrendered without a fight, and the PLA marched into the old imperial capital on 31 January.
Urban unrest is on the spec for a reason. By 1947–48 the cities the GMD relied on were in chaos: shopkeepers shut their doors against worthless currency, students staged hunger strikes against corruption (the ‘Anti-Hunger, Anti-Civil-War’ movement of 1947), and civil servants drifted away from work because their salaries had no purchasing power. The CCP had communist activists in many universities, and underground urban networks ran propaganda and intelligence. Strong answers connect the rural war to the urban collapse — one without the other does not explain 1949.
1 October 1949: The People’s Republic
On 1 October 1949, Mao stood on the Tiananmen rostrum and proclaimed the People’s Republic of China. The image — broadcast and printed in posters within hours — became one of the iconic moments of the twentieth century. By December, Chiang Kai-shek had retreated with his remaining troops, the GMD government and a substantial portion of China’s gold reserves to the island of Taiwan, where the Republic of China would survive as a separate state. Mao now ruled around 540 million people. The CCP had grown from c.40,000 members in 1937 to roughly 4.5 million in 1949.
By October 1949 Mao’s victory had several roots: PLA strategy and discipline (military), GMD corruption and brutal conscription (political), and hyperinflation that destroyed urban GMD legitimacy (economic). Each fed the other; no single factor is enough on its own.
