The Chinese Civil War

China had become a republic in 1912, but regional military rulers still controlled much of the country. The Nationalist Party, also called the Kuomintang or KMT, wanted a strong, united state. The Chinese Communist Party, or CCP, wanted a socialist revolution.

The parties had worked together, with Soviet help, to defeat those regional rulers. Chiang Kai-shek led the Northern Expedition, a military campaign launched in 1926.

“An army could reunite territory while its allies fought over the future.”

In April 1927, forces aligned with Chiang violently suppressed Communists and labour organisers in Shanghai. Further purges destroyed the alliance. Communist uprisings later that year failed to secure the major cities.

The survivors faced a new question: could a revolution defeated in the cities find strength in the countryside?

Most Chinese people lived by farming. Many rented land, owed debts or struggled to feed their families. Promises to redistribute land could attract support where village life felt unfair.

Mao Zedong and other Communist leaders built rural bases protected by armed forces. In 1931, they established the Chinese Soviet Republic in Jiangxi, a rival government inside China.

“Control of a village meant more than control of its fields.”

The Communists collected supplies, recruited soldiers and changed local authority. Some villagers welcomed them. Others faced pressure, confiscation or violence. Rural support was never a simple story of universal enthusiasm.

Chiang’s government launched repeated campaigns to destroy these bases. The Communists had found a place to survive, but keeping it would prove much harder.

Nationalist armies had tightened their blockade around Jiangxi. Remaining there risked destruction. The main Communist force broke out in October and moved across western China.

The journey brought battles, hunger, exhaustion and difficult mountain crossings. Many people died or left the columns. Other Communist armies made separate retreats.

“Survival would later be remembered as a victory.”

Mao strengthened his position during the march, especially after the Zunyi meeting in early 1935. The main force reached northern Shaanxi later that year; other forces arrived in 1936.

The survivors were much weaker in numbers but had escaped destruction. The party later turned their ordeal into a heroic founding story. Remembering that story also means recognising the losses behind it.

Japan had seized Manchuria in 1931. Chiang continued to prioritise defeating the Communists, arguing that China needed internal order before it could resist effectively.

In December 1936, generals Zhang Xueliang and Yang Hucheng detained Chiang at Xi’an. Negotiations helped secure his release and opened a path towards renewed cooperation.

“A shared enemy could interrupt a civil war without resolving it.”

Full-scale war with Japan began in 1937. Nationalists and Communists formed a Second United Front, but kept separate organisations and deep suspicions.

The Nationalist armies fought major battles, while Communist forces expanded resistance networks behind Japanese lines. Fighting between the two Chinese sides never disappeared completely. Their uneasy cooperation bought time, but left the argument over China’s future unsettled.

Nationalist armies suffered heavy losses. The government moved inland as important cities and productive regions fell under occupation. Keeping armies supplied placed severe demands on ordinary people.

Communist bases expanded in the countryside. Organisers linked resistance to village government, recruitment and promises of social change.

“A movement could grow by governing the places another state struggled to reach.”

The Communist base at Yan’an became a political centre. Mao strengthened his authority, while campaigns to enforce party discipline involved pressure and persecution as well as education.

Neither side offered freedom from hardship. Villagers faced taxation, recruitment and violence from several directions. By 1945, China was deeply damaged, and the rivals waiting to inherit it were no longer the same forces that had entered the war.

Chiang’s government held international recognition and American support. United States transport helped Nationalist forces reach important areas. The Communists drew strength from northern rural bases.

Manchuria was especially valuable because of its railways and industry. Soviet occupation after Japan’s defeat complicated the struggle over who would take control.

“Peace required an agreement about armies, territory and power.”

Mao and Chiang met in Chongqing. Their October agreement promised political cooperation, but neither side trusted the other enough to give up its military position.

American general George Marshall then tried to mediate. A ceasefire in early 1946 briefly raised hopes, but local fighting and unresolved disputes undermined it. The chance to rebuild together was closing.

The Nationalists began with more troops, major cities and stronger equipment. Chiang expected military pressure to break Communist resistance. His armies advanced into contested areas.

The Communists often withdrew rather than defend every town. They sought opportunities to isolate enemy units and build strength in the surrounding countryside.

“An advance could capture territory while making an army harder to supply.”

In 1947, Nationalist forces took Yan’an, the Communist political centre. Yet Mao’s movement survived, and its armies increasingly moved onto the offensive.

For civilians, renewed war meant more displacement, recruitment and demands for food. The outcome depended on military decisions, but also on whether governments could keep people willing, or able, to support them.

The Communists expanded land redistribution during the later civil war. Giving poorer farmers land could connect their future to a Communist victory. Village organisations helped supply and recruit for the army.

But reform also brought coercion, public accusations and killings. Support for the revolution did not erase the suffering it caused.

“The battle for power reached into fields, households and market stalls.”

The Nationalist government faced mounting inflation. Printing money helped pay for the war, but prices raced ahead of wages and savings. A currency reform in 1948 failed to restore confidence.

Military failures, economic hardship and repression weakened Chiang’s government together. Communist organisation gained strength as the state’s promises became harder to believe.

The Liaoshen campaign gave the Communists control of Manchuria. The Huaihai campaign destroyed major Nationalist forces around Xuzhou. The Pingjin campaign secured the Beijing-Tianjin region.

These were large conventional operations, supported by rural transport and supplies. Communist armies were no longer simply guerrilla forces avoiding stronger opponents.

“The war’s balance changed when whole armies could no longer recover.”

Civilian suffering remained severe. Sieges cut off food, and people caught between armies faced hunger and displacement. Victory on a map could conceal disaster inside a city.

In April 1949, Communist forces crossed the Yangtze and captured Nanjing. Shanghai followed in May. The Nationalist government was losing the mainland, although fighting continued elsewhere.

The People’s Republic of China was founded on 1 October. Communist victories continued after the announcement. Nationalist leaders, soldiers and civilians moved to Taiwan, where the Republic of China government survived.

Taiwan already had its own communities and a painful recent history. Nationalist repression after the 1947 uprising and martial law imposed in 1949 shaped the lives of its people.

“The mainland had a victor. The wider conflict had no agreed peace.”

Both governments claimed to represent China. Fighting continued after 1949, and the Korean War brought American naval intervention in the Taiwan Strait in 1950.

The civil war explains the origins of the divide. Later Communist rule and Taiwan’s democratic development belong to the next chapters of the story.
