The Japanese invasion of the Chinese region of Manchuria began on September 19, 1931, following the Mukden incident, in which the Japanese acused Chinese dissidents of a sabotage attempt against the Japanese railroad company South Manchuria Railway. It was the Imperial Japanese Army’s officers who, in fact, had orchestrated the Mukden incidents by planting themselves a bomb in the railroad tracks, accusing the Chinese for this. This concocted incident gave Japan a justification for invading Manchuria.
In the morning of September 19, 1931, Japanese troops attacked the Chinese Army’s outpost of Mudken, the capital of Manchukuo (Manchuria). The following day the garrison was taken as hundreds of Chinese soldiers fled southward. In October, two more Japanese infantry divisions would be sent to this region in Northern China. In mid November, a puppet figure would be established as the government of Manchuria: the Chinese emperor Puyi. Open and full scale hostilities between Japan and China would break out in 1937, signalling the beginning of the Sino-Japanese War.
