Xinhai Revolution

What happened

Qing Dynasty weakened by foreign imperialism, internal corruption, and failed reforms. Revolutionary movements (Sun Yat-sen's alliance) gained support. Military uprising (Oct 1911) in Wuhan sparked wider revolt. Provincial governments declared independence; Qing lost control. The dynasty fell; Sun Yat-sen became provisional president. A republic was proclaimed (1912). However, military strongman Yuan Shikai became president and marginalized Sun. The revolution established a republic nominally but did not end warlordism or foreign domination. Perhaps 10,000-50,000 died in fighting, though casualty figures are imprecise.

Why it mattered

The Xinhai Revolution ended imperial China after 2,000+ years. It established a republic and the concept of democratic governance (however imperfectly implemented). The revolution inspired Chinese nationalism against foreign imperialism. However, the revolution's ideals were quickly betrayed: warlordism, foreign occupation, and internal conflict persisted. The revolution created space for communist and nationalist movements that eventually unified China (1949). Sun Yat-sen's Three Principles (nationalism, democracy, socialism) influenced Chinese politics for decades. The revolution's failure to immediately establish strong government contributed to Japan's invasion (1937) and China's century of humiliation. Modern China invokes the revolution as founding moment of Chinese modernity.
