Republic of China (1912–1949) capital Nanjing
1937–1945: Second Sino-Japanese War
Few Chinese had any illusions about Japanese desires on China. Hungry for raw materials and pressed by a growing population, Japan initiated the seizure of Manchuria in September 1931 and established the ex-Qing emperor Puyi as head of the puppet state of Manchukuo in 1932. The loss of Manchuria, and its potential for industrial development and war industries, was a blow to the Kuomintang economy. The League of Nations, established at the end of World War I, was unable to act in the face of Japanese defiance.
The Japanese began to push south of the Great Wall into northern China and the coastal provinces. Chinese fury against Japan was predictable, but anger was also directed against Chiang and the Nanjing government, which at the time was more preoccupied with anti-Communist extermination campaigns than with resisting the Japanese invaders. The importance of "internal unity before external danger" was forcefully brought home in December 1936, when Chiang Kai-shek, in an event now known as the Xi'an Incident, was kidnapped by Zhang Xueliang and forced to ally with the Communists against the Japanese in the Second Kuomintang-CCP United Front.
Chinese resistance stiffened after 7 July 1937, when a clash occurred between Chinese and Japanese troops outside Beiping (Later Beijing) near the Marco Polo Bridge. This skirmish led to open, although undeclared, warfare between China and Japan. Shanghai fell after a three-month battle during which Japan suffered extensive casualties in both its army and navy. The capital, Nanjing, fell in December 1937, which was followed by mass murders and rapes known as the Nanjing Massacre. The national capital was briefly at Wuhan, then removed in an epic retreat to Chongqing, the seat of government until 1945. In 1940, the Japanese set up the collaborationist Wang Jingwei regime, with its capital in Nanjing, which proclaimed itself the legitimate "Republic of China" in opposition to Chiang Kai-shek's government, although its claims were significantly hampered due to its being a puppet state controlling limited amounts of territory.
