This thesis surveys activities of Korean troops who served in the region of the South East Asia for the 1st army of the allies in the Far East against Japanese imperialism, and approaches to their historical meaning based on this survey. First of all, the thesis investigates the development of the so-called Japanese Security Enforcement Operation after the establishment of the Republic of Manchuria, and especially their military oppression from which resistant movements forces in the South East region suffered. Secondly, the thesis looks into the development of the resistant rangers who confronted against Japan in the region of the South East Asia, along with focusing on Koreans' activities at the time of the establishment of the 1st army of the allies in the Far East. Thirdly, it looks into the activities of those who are classified 'revolutionary patriots' from those Korean troops involved in the 1st army of the allies and the difference of awareness in academic worlds of China, South Korea and North Korea. The writer hopes that it will contribute to aware more concretely the activities of Korean troops in the 1st army of the allied force in the Far Hast in the struggle against Japanese imperialism in the region of Manchuria in the 1930s. Referring to their activities, Korean troops in the 1st army of the Far East Allies are thought to be active and strong resistance against Japanese imperialism in the military struggle against Japan that had been kept spreading since the Manchurian Incident. As we analyse the activities of the persons who are respected as Chinese national hero in China today, it seems that some of their activities should be apprehended with regard to Korean Independence Movement despite that they worked for Chinese Communist Party. But this is something that needs more investigations and more analyses. Current inquiries on the activities of Korean troops are mostly focused on revolutionary patriots. But it seems that the object of inquiry should be expanded more than that. If possible, even those activities before joining Chinese Communist Party should be explored in more detail.
