This essay focuses on the formation of war-footing in North Korea in the initial stage of Korean War. In order to accomplish this purpose, North Korea’s the wartime laws and its reorganization of state institutions in Korean war was compared with the case of Soviet Union in the Great Patriot War period. North Korea’s wartime law system was based on the ‘wartime condition’ which has often misunderstood in the meaning of ‘state of war’. However it was a ‘state of siege’ or a martial law which is originated from Tsarist Russia’s emergency state law.

The reorganization of local regime was proceeded on the basis of ‘the state of siege’ system and it was soon changed to the new system on which Labor Party took the lead. North Korea was confronted with US and South Korean’ counterattack, and in every regions was founded the local Military Defence Committee. In this essay the founding of the local Military Defence Committee was interpreted as an abrogation of the early ‘wartime condition’ system.
