Overview
Sun Yat-sen (also Sun Zhongshan and Sun Wen; 12 November 1866 – 12 March 1925) was a central figure in the transition of China from imperial rule to a republican state. He is widely regarded as one of the founders of the Republic of China and is frequently called the "Father of the Nation" in Taiwan. For concise biographical summaries see biographical summaries.
Early life and education
Sun was born in Guangdong province and spent part of his youth abroad. He received a Western-style education, including time in Hawaii, and later studied medicine in Hong Kong, where he qualified as a physician before devoting himself to politics. His medical training and early contacts with overseas Chinese communities shaped his networks and methods of organizing. Further information on his schooling and early influences is available at historical records.
Revolutionary activity
Over several decades Sun organized political societies and revolutionary groups and worked with compatriots both inside China and among Chinese diaspora communities. He helped unify various anti-Qing factions and was a key figure in the 1911 Xinhai Revolution that led to the fall of the Qing dynasty. He briefly served as provisional president when the Republic of China was proclaimed in 1912. For primary documents on the republic's founding see founding documents.
Party building and later politics
Sun was a founder and leading organizer of the Kuomintang (Nationalist Party). He sought to turn revolutionary momentum into a modern political party capable of national reconstruction. His efforts included political education, fundraising among overseas Chinese, organizational work and occasional cooperation with other political forces. The early development of the Kuomintang is discussed in detail at party history.
Political ideas: The Three Principles of the People
Sun articulated a program for national renewal commonly known as the Three Principles of the People. These principles were intended as a practical guide for state-building and social reform and remain influential in 20th-century Chinese history:
- Nationalism — the assertion of national independence and unity after a period of foreign intervention and imperial weakness;
- Democracy — the aim of representative government, constitutional rule, and popular participation in state affairs;
- Livelihood — concern for social welfare, economic modernization and measures to improve living standards.
These ideas were presented as a program for modernization rather than a finished ideology; they were interpreted and adapted by later movements and leaders. Scholarly discussions and assessments of Sun's thought can be found at scholarly reviews.
Later years, alliances and death
Sun continued to travel, organize and seek international support for his vision of a unified, modern China. In the 1920s he participated in efforts that led to a cooperative period between his party and the Chinese Communist movement, aimed at national unification and resisting warlord rule. He died in 1925 before achieving stable national reunification; historians note both his symbolic achievements and the limits of his direct political control.
Legacy and commemoration
Sun's legacy is unusual in that he is officially honored in both the People's Republic of China and the Republic of China (Taiwan). Monuments, memorial halls, academic studies and public ceremonies recall his role in the end of imperial rule and the promotion of modern political ideas. A large portrait of Sun is still displayed in Tiananmen Square on major civic occasions; descriptions of public commemorations and visual records are available at Tiananmen records and national celebrations. His place in Taiwanese memory and archives is addressed at Taiwanese archives.
