Mukden incident

The Mukden incident was a false flag event staged by Japanese military personnel as a pretext for the 1931 Japanese invasion of Manchuria. On September 18, 1931, Lieutenant Suemori Kawamoto of the Independent Garrison Unit of the 29th Japanese Infantry Regiment detonated a small quantity of dynamite close to a railway line owned by Japan's South Manchuria Railway near Mukden (now Shenyang).
