📖 Setting the Scene
September 18, 1931. An explosion damages the Japanese-owned South Manchurian Railway near Mukden. Japan claims Chinese saboteurs are responsible and uses this as an excuse to invade the entire region — an area three times the size of Britain. The explosion was almost certainly staged by Japanese army officers. China appealed to the League of Nations. What followed exposed the League as a "paper tiger" — lots of words, no action. The Lytton Report condemned Japan in October 1932; the League formally voted in February 1933; Japan simply walked out in March 1933. Manchuria remained in Japanese hands, renamed "Manchukuo."
What was Manchukuo?: Puppet state created by Japan in Manchuria with Pu Yi as figurehead
