18h 22min, sep 19, 1931 y - Manchurian Invasion (began at this date)
Description:
Japan, which was hungry for resources, decided to invade the resource-rich region of Manchuria that bordered their territory. They staged an attack to invade Manchuria. China appealed to the League, which did very little in response--they were too scared to act. Even sending a Lytton Commission to judge the situation was too late.
