China (People’s Republic of China and the modern Chinese state)

Historical overview

China has one of the world’s longest continuous recorded histories, with successive dynasties, major philosophical traditions, technological achievements and regional cultural systems. Its modern political history was shaped by the decline of the Qing dynasty, foreign intervention, revolution, warlord competition, Japanese invasion and civil war.

The Xinhai Revolution of 1911 ended Qing imperial rule. The Republic of China was formally established in 1912. The May Fourth Movement of 1919 became a significant student-led political and cultural movement, raising questions about national sovereignty, modernisation and the future of Chinese society. The Chinese Communist Party was founded in 1921.

The Second Sino-Japanese War began in 1937 and became part of the wider Second World War. Following Japan’s defeat in 1945, civil war between the Chinese Communist Party and the Nationalist government resumed. On 1 October 1949, Mao Zedong proclaimed the establishment of the People’s Republic of China in Beijing. The Nationalist government continued in Taiwan, where the Republic of China government remains based.

The early decades of the People’s Republic included major political and social campaigns. The Great Leap Forward (1958–62) resulted in severe economic disruption and a catastrophic famine. The Cultural Revolution (1966–76) brought widespread persecution, political violence and disruption to education and cultural institutions.

After Mao’s death in 1976, China moved toward economic reform and opening under Deng Xiaoping, beginning in 1978. These reforms transformed the economy and society. The 1989 pro-democracy demonstrations in Beijing and other cities ended in a military crackdown. The events and the number of people killed remain subjects of historical investigation, and public discussion within mainland China is heavily restricted.
