Edexcel IGCSE History: China, Conflict, Crisis and Change, 1900–89 (4HI1)

Breadth Study B4, “China: conflict, crisis and change, 1900–89”, is one of eight breadth studies in change in Section B of Pearson Edexcel International GCSE History (4HI1) Paper 2. It covers nearly a century: the collapse of the Qing dynasty, the warlord era and the struggle between the Guomindang (GMD) and the Chinese Communist Party (CCP), Mao Zedong’s victory in 1949 and the upheavals of his rule, and Deng Xiaoping’s economic reforms up to the Tiananmen Square crackdown of 1989.

Syllabus coverage

The specification (Issue 5, February 2026) names five themes: civil conflict — order and disorder; external influences on China; economic transformation; social transformation; and the role of leadership. The (c) essay normally draws on two or more key topics. The five key topics are:

1. The fall of the Qing, Warlordism and chaos, 1900–34 — the Boxer Uprising and late Qing reforms, the 1911 Revolution, the Warlords, the May Fourth Movement, Sun Yat-sen, Chiang Kai-shek and the GMD, the CCP, the United Front and Soviet influence, the Northern Expedition, the Shanghai Massacres and the Extermination Campaigns.
2. The triumph of Mao and the CCP, 1934–49 — the Long March (1934–35), war with Japan (1937–45), the Civil War (1946–49), the Battle of Huai-Hai and the reasons for CCP success.
3. Change under Mao, 1949–63 — the first Five-year Plan, the attack on landlords, the Agrarian Reform Law, cooperatives and collectives, women, Thought Reform, the Three- and Five-anti Campaigns, the Hundred Flowers, the Great Leap Forward and Soviet influence.
4. The Cultural Revolution and its impact, 1965–76 — Mao’s motives, the Red Guards, education and the cult of Mao, the impact on China and Mao’s position, and the economic effects of the Sino-Soviet split.
5. China, 1976–89 — the Gang of Four, Deng’s changes in education, birth control, agriculture and industry, his opposition to political reform, privatisation and westernisation, the Democracy Wall and Wei Jingsheng, student protest from 1986, and Tiananmen Square (1989).

Why did the Qing fall and China descend into chaos, 1900–34?

The Boxer Uprising (1899–1901), an anti-foreign movement backed by the Empress Dowager Cixi, was crushed by an eight-nation force, and China paid a huge indemnity. The Qing then attempted reforms — abolishing the old civil service examinations (1905), building a New Army and allowing provincial assemblies — but these created new critics. After an army revolt at Wuchang in October 1911, provinces declared independence; Sun Yat-sen became provisional president, and the last emperor, Puyi, abdicated in 1912. General Yuan Shikai took power but died in 1916, and China broke up under rival warlords.

On 4 May 1919 students protested in Beijing against the Treaty of Versailles giving Germany’s rights in Shandong to Japan. The May Fourth Movement spread new ideas, including Marxism. Sun’s Guomindang reorganised with Soviet help, and the CCP was founded in 1921. Under Soviet advice the two formed a United Front (from 1923–24). After Sun’s death (1925), Chiang Kai-shek led the Northern Expedition (1926–28) against the warlords, but in April 1927 he turned on the communists in the Shanghai Massacre. The CCP retreated to the countryside, where Chiang’s Extermination (Encirclement) Campaigns (1930–34) eventually forced it out of its Jiangxi base.

How did Mao and the CCP triumph, 1934–49?

On the Long March (1934–35) the Red Army escaped encirclement and trekked thousands of kilometres to Yan’an in the north-west; only a fraction of those who set out arrived, but Mao emerged as leader after the Zunyi Conference (1935), and the march became a powerful legend. After the Xi’an Incident (1936) the GMD and CCP formed a second united front against Japan. In the war with Japan (1937–45) the GMD bore the brunt of major battles and retreated inland, becoming weakened by losses, inflation and corruption, while the CCP’s Red Army used guerrilla warfare and land reform to win peasant support in the north.

In the Civil War (1946–49) the CCP’s People’s Liberation Army won in Manchuria and then destroyed huge GMD forces at Huai-Hai (1948–49). Reasons for success: military (guerrilla experience, morale, captured weapons, defections), political (Mao’s leadership, discipline, propaganda), economic (GMD hyperinflation) and social (land reform and peasant support). Mao proclaimed the People’s Republic on 1 October 1949; Chiang fled to Taiwan.

What changed under Mao, 1949–63?

The Agrarian Reform Law (1950) redistributed land; landlords were denounced at mass meetings and many were killed. Peasants were then organised into mutual-aid teams, cooperatives and, by 1956, collectives. The first Five-year Plan (1953–57), with Soviet loans and experts, expanded heavy industry. The Marriage Law (1950) banned arranged marriages and allowed divorce, improving the role of women. Thought Reform and the Three-anti (against corruption among officials) and Five-anti (against businessmen) campaigns tightened control. In the Hundred Flowers Campaign (1956–57) Mao invited criticism, then punished critics in the Anti-Rightist campaign.

The Great Leap Forward (1958–62) aimed to overtake Britain’s industrial output through communes and backyard steel furnaces. Unrealistic targets, false reporting and the neglect of farming caused a famine in which tens of millions died. Mao gave up the post of head of state to Liu Shaoqi. Relations with the Soviet Union broke down, and in 1960 Soviet advisers were withdrawn — the Sino-Soviet split.

Why did Mao launch the Cultural Revolution, and what were its effects?

Mao’s motives included regaining power from pragmatists such as Liu Shaoqi and Deng Xiaoping, purging the party of “capitalist roaders” and renewing revolutionary spirit in the young. From 1966 millions of Red Guards, carrying the “Little Red Book” of Mao’s quotations, attacked the “Four Olds”, teachers and officials. Education collapsed as schools and universities closed, and the cult of Mao reached its height. Liu died in prison and Deng was sent to work in a factory. From 1968 the Red Guards were sent to the countryside. Mao’s position was restored, but the economy and culture were badly damaged. The Sino-Soviet split deepened, with border clashes in 1969, cutting China off from Soviet aid and technology.

How did China change under Deng, 1976–89?

After Mao died in September 1976, the radical Gang of Four, including Mao’s widow Jiang Qing, were arrested and later tried. Deng Xiaoping became the dominant leader from 1978. In agriculture, the household responsibility system let families sell surplus produce; in industry, Special Economic Zones opened to foreign investment, and private businesses grew — privatisation and westernisation. University entrance exams were restored in education, and the one-child policy (from 1979–80) limited birth control choices.

Deng refused political reform. Posters on the Democracy Wall (1978–79) called for change; Wei Jingsheng demanded a “Fifth Modernisation” — democracy — and was imprisoned. University students protested from 1986. After the death of the reformer Hu Yaobang in April 1989, students occupied Tiananmen Square calling for democracy and an end to corruption. Deng approved martial law, and on 4 June 1989 the army cleared the square, killing many — the true number is unknown.

Frequently asked questions

Why did the CCP win in 1949? Weigh Mao’s leadership and peasant support against GMD weakness, corruption and the effects of the war with Japan.

Was Deng’s China a break with Mao’s? Economically yes; politically, one-party rule continued.

What is the best theme for a long essay? Leadership (Sun, Chiang, Mao, Deng) or economic transformation.
