Deng Xiaoping Theory in the context of "Reform and opening up"

Deng Xiaoping (22 August 1904 – 19 February 1997) was a Chinese statesman, revolutionary, and political theorist who served as the paramount leader of the People's Republic of China (PRC) from 1978 to 1989. Emerging as China's most influential figure after Mao Zedong's death in 1976, Deng consolidated political power and guided the country into an era of "reform and opening up" that transitioned the nation toward a socialist market economy. Credited as the "Architect of Modern China", he is recognized for shaping both socialism with Chinese characteristics and Deng Xiaoping Theory.

Born into a landowning peasant family in Sichuan, Deng was introduced to Marxism–Leninism while studying and working in France during the 1920s as part of the Work–Study Movement. He then studied in Moscow and, after returning to China, joined the Chinese Communist Party (CCP) in 1924. During the Chinese Civil War, he worked in the Jiangxi Soviet and maintained close ties with Mao. Deng later served as a political commissar in the Chinese Red Army during the Long March and Second Sino-Japanese War, helping secure CCP victory in 1949 and taking part in the People's Liberation Army (PLA) capture of Nanjing.

The Chinese Communist Party (CCP) frames its ideology as Marxism–Leninism adapted to the historical context of China, which it calls the Sinicization of Marxism, often expressing it as socialism with Chinese characteristics. Major ideological contributions of the CCP's leadership are viewed as "Thought" or "Theory," with "Thought" carrying greater weight. Influential concepts include Mao Zedong Thought, Deng Xiaoping Theory, and Xi Jinping Thought. Other important concepts include the socialist market economy, Jiang Zemin's idea of the Three Represents, and Hu Jintao's Scientific Outlook on Development.
