Causes and Course of the First Sino-Japanese War (1894–1895)

- Japan, modernized under the Meiji reforms, had built a strong army and navy modeled on Western powers.
- China’s military lagged behind due to failed reforms like the Self-Strengthening Movement.
- The immediate cause was the Donghak Rebellion (1894) in Korea, prompting both nations to send troops.
- Japan’s superior organization and technology led to quick victories on land and sea, including at Pyongyang and the Yalu River.
