When did the Pacification of Manchukuo begin?
Pacification of Manchukuo
The Pacification of Manchukuo was a Japanese anti-insurgency campaign during the Second Sino-Japanese War to suppress any armed resistance to the newly established puppet state of Manchukuo from various anti-Japanese volunteer armies in occupied Manchuria and later the Communist Northeast Anti-Japanese United Army. The operations were carried out by the Imperial Japanese Kwantung Army and the collaborationist forces of the Manchukuo government from March 1932 until 1942, and resulted in a Japanese victory.
Jiandao
After the Mukden Incident of 1931, the Japanese military (the Kwantung Army) invaded Manchuria. Between 1931 and 1945, Manchuria was under the control of Manchukuo, a Japanese puppet state. From 1934 the area formed a new Jiandao Province of Manchukuo after the old Jilin Province was split into Binjiang, Jiandao and a rump Jilin. This period initiated a new wave of Korean immigration, as the Japanese government actively encouraged (or forced) Korean settlement in order to colonize and develop the region. The Japanese also moved to suppress resistance in the region. Within three and half years (from September 1931 to March 1935), Japanese regular forces and police murdered 4520 people. During and after the 1930s, many ethnic Koreans in the region joined and participated in the Chinese Communist Party.
