Americans think of WW2 in Asia as having begun with Pearl Harbor, the British with the fall of Singapore, and so forth. The Chinese would correct this by identifying the Marco Polo Bridge incident as the start, or the Japanese seizure of Manchuria earlier. It really began in 1895 with Japan's assassination of Korea's Queen Min, and invasion of Korea, resulting in its absorption into Japan, followed quickly by Japan's seizure of southern Manchuria, etc. - establishing that Japan was at war from 1895-1945. Prior to 1895, Japan had only briefly invaded Korea during the Shogunate, long before the Meiji Restoration, and the invasion failed.
