The Marco Polo Bridge Incident, also known as the July 7 Incident, was a July 1937 battle between China's National Revolutionary Army and the Imperial Japanese Army.
The incident is generally regarded as the start of the Second Sino-Japanese War. On the night of July 7, 1937, Japanese troops carried out unauthorized maneuvers near the Marco Polo Bridge and demanded entry to the walled town of Wanping to search for a missing soldier. The refusal led to gunfire and escalation into full-scale war.
