North Korea
Japan tried to suppress Korean traditions and culture and ran the economy primarily for its own benefit. Korean resistance groups known as Dongnipgun (Liberation Army) operated along the Sino-Korean border, fighting guerrilla warfare against Japanese forces. Some of them took part in allied action in China and parts of South East Asia. One of the guerrilla leaders was the communist Kim Il-sung, who later became the first leader of North Korea.
O Jin-u
Marshal Oh Jin-Woo (March 8, 1917 – February 25, 1995) was a soldier and politician of North Korea. He was the Minister of Armed Forces for many years until his death in February 1995. Oh was the third most powerful person in North Korea, after Kim Il-Sung and Kim Jong-Il (therefore the most powerful person that possessed no blood relations to the Kim family). Very little is known about him except for the fact that he served with Kim Il-sung's partisan unit and eventually rose through the ranks of the North Korean Army. He distinguished himself during the Korean War and was a trusted adviser of the North Korean leader until his death, also being his chief guard in 1945.
