Conscription in South Korea
The basis for military conscription in South Korea is the Constitution of the Republic of Korea, which was promulgated on July 17, 1948. The constitution states in Article 39, "All citizens shall have the duty of national defense under the conditions as prescribed by Act." The Military Service Act of 1949, which was implemented in 1957, specified that compulsory military service is required for men ages 19 or older. Conscription is managed by the Military Manpower Administration, which was created in 1948.
Korea under Japanese rule
On 10 December 1941, the Provisional Government of the Republic of Korea, under the presidency of Kim Gu, declared war on Japan and Germany. Kim Gu organized many of the exiled Korean resistance groups, forming the "Korean Liberation Army". On the other hand, Kim Il-sung led tens of thousands of Koreans who volunteered for the National Revolutionary Army and the People's Liberation Army. The communist-backed Korean Volunteer Army (KVA, 조선의용군, 朝鮮義勇軍) was established in Yenan, China, outside of the Provisional Government's control, from a core of 1,000 deserters from the Imperial Japanese Army. After the Manchurian Strategic Offensive Operation, the KVA entered Manchuria, where it recruited from the ethnic Korean population and eventually became the Korean People's Army of the Democratic People's Republic of Korea.
