Quick Summary

The Kwantung Army was a contingent of the Japanese Imperial Army stationed in Manchuria. In 1931, officers of this army, without the Japanese government's approval, staged the Mukden Incident. Using a minor explosion on the South Manchurian Railway as a pretext, they occupied Mukden and subsequently invaded all of Manchuria. This led to the establishment of the Japanese-controlled puppet state of Manchukuo in 1932. The Kwantung Army's actions contributed to Japan's international isolation and were a significant step toward World War II. The army continued to exert control, even as the Japanese government attempted to manage foreign relations and expand its influence in East Asia.1234
