China from the Opium War to the People's Republic (Class 11 History, Theme 7)

Updated 17 October 2026 · Fact-checked

China's path began with the Opium War (1839-42) and the failure of Qing reforms. The 1911 republic under Sun Yat-sen, the May Fourth Movement (1919) and the Guomindang preceded the Communist Party's peasant-based rise under Mao. The People's Republic was set up in 1949; Deng Xiaoping's reforms from 1978 introduced a socialist market economy.

Understand China: Opium War, Republic, Communist Rise and the People's Republic

Why this topic matters. The syllabus compares China and Japan: both modernised, but by different routes. Use neutral, attributed language for political questions.

1. Geography and sources. China is vast, with the Yellow River, the Yangtse (third longest in the world) and the Pearl River. Han are the dominant group, Putonghua the main language, with Uighur, Hui, Manchu and Tibetan nationalities.

2. Opium trade. Chinese tea, silk and porcelain were wanted, but Western goods did not sell in China, so payment was in silver. The East India Company sold opium grown in India in China and used the silver gathered at Canton to buy goods for Britain: a triangular trade between Britain, India and China. Britain used force to expand opium trade, leading to the first Opium War (1839-42), which undermined the Qing.

3. Reformers. Kang Youwei and Liang Qichao wanted a modern administration, army, education and local assemblies. Fear of being partitioned like Poland ("to Poland us") and of India's fate worried Chinese thinkers. Confucianism came to be seen by some as a barrier. Students went to Japan, Britain and France.

4. Examination system. Entry to the elite was by an eight-legged essay in classical Chinese; only 1-2 per cent passed the first level. There were about 27,000 official posts against hundreds of thousands of degree holders, and the system hindered science and technology. It was abolished in 1905.

5. The republic. In 1911 the Manchu empire was overthrown and a republic set up under Sun Yat-sen (1866-1925). His Three Principles: nationalism, democracy and socialism (regulating capital and equalising landholdings).

6. May Fourth (1919). Beijing students protested that China, though on the winning side, did not get back its territories at the peace conference. The movement called for modern science, democracy and nationalism, simple written language, ending foot-binding and equality in marriage.

7. The Guomindang. After Sun's death, Chiang Kai-shek (1887-1975) led a campaign against warlords and communists. The GMD had an urban base and ignored the peasantry; Sun's plans for land equalisation were not carried out.

8. The Communist rise. The Japanese invasion of 1937 and war weakened China; prices rose 30 per cent a month between 1945 and 1949. The CCP (founded 1921) under Mao Zedong (1893-1976) based revolution on the peasantry. In Jiangxi (1928-34) it redistributed land and passed a marriage law against arranged marriages. The Long March (1934-35) of about 6,000 miles led to Yanan.

9. People's Republic. Established in 1949 on the principle of New Democracy, an alliance of classes. The Great Leap Forward (1958) brought backyard steel furnaces and people's communes (26,000 communes covering 98 per cent of the farm population). The Cultural Revolution, launched by Mao against critics who valued expertise over ideology, used Red Guards and caused turmoil in education and the economy.

10. Reforms after 1978. Deng Xiaoping kept strong party control while introducing a socialist market economy and the Four Modernisations (science, industry, agriculture, defence). A 1978 wall poster demanded a fifth modernisation, democracy, and such demands were suppressed; in 1989 student demonstrators at Tiananmen Square were repressed. Post-reform debates concern inequalities and the revival of Confucian ideas.

11. Taiwan. Chiang Kai-shek moved to Taiwan in 1949 and set up the Republic of China. Land reform and trade-based growth took Taiwan's GNP by 1973 to second in Asia after Japan; martial law was lifted in 1987.

By 1975 the party again stressed discipline and building an industrial economy.

    Answer

    Taiwan, under the GMD, had a repressive government at first but land reforms and trade-based growth made its GNP second in Asia to Japan by 1973, and martial law ended in 1987 with democratisation. The mainland, under the CCP from 1949, pursued New Democracy, communes and later a socialist market economy under strong party control, with debates about inequality and democracy. Taiwan's relations with the mainland remain a contested question.
