Kim Gu
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.
