After blowing up a railroad junction, Japanese troops quickly occupied Manchuria and established a puppet state in 1932.

Explanation:

The Japanese invasion of Manchuria by the Kwantung Army of the Empire of Japan began on September 19, 1931, immediately after the Mukden Incident, in which Japanese soldiers blew up a railroad junction that belonged to a Japanese company, to incriminate China and invade its territory. The Japanese occupation of Manchuria lasted until the end of World War II and would lead to the founding of the puppet state of Manchukuo.
