Concept note-1: -On September 18, 1931, the Manchurian (Mukden) Incident marked the dawn of Japanese military aggression in East Asia. The Kwantung Army alleged that Chinese soldiers had tried to bomb a South Manchurian Railway train. Damage to the railway was minimal and the train arrived at its destination safely.
Concept note-2: -The Manchurian Crisis 1931-1933 followed the Mukden Incident in which Japanese rail tracks were destroyed in an explosion. Claiming that it was saboteurs, the Japanese responded with force, taking control of the Chinese province of Manchuria.
Concept note-3: -The Manchurian Crisis of 1931–33 demonstrated the futility of the 1920s-era agreements on peace, nonaggression and disarmament in the face of a power determined to march forward.
Concept note-4: -The events in Manchuria became an international crisis because Japan, who was in the League of Nations, invaded Manchuria. What made this even more wrong than it already was, was that Japan was a permanent member of The League. Therefore it damaged The League’s reputation.
