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). The explosion was so weak that it failed to destroy the track, and a train passed over it minutes later. The Imperial Japanese Army accused Chinese dissidents of the act and responded with a full invasion that led to the occupation of Manchuria, in which Japan established its puppet state of Manchukuo five months later.
