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.
History of North Korea
Kim Il-sung died from a sudden heart attack on July 8, 1994, three weeks after the Carter visit. His son, Kim Jong-il, who had already assumed key positions in the government, succeeded as General Secretary of the Korean Workers' Party. At that time, North Korea had no secretary-general in the party nor a president. What minimal legal procedure had been established was summarily ignored. Although a new constitution appeared to end the wartime political system, it did not completely terminate the transitional military rule. Rather it legitimized and institutionalized military rule by making the National Defense Commission (NDC) the most important state organization and its chairman the highest authority. After three years of consolidating his power, Kim Jong-il became Chairman of the NDC on October 8, 1997, a position described by the NDC as the nation's "highest administrative authority", and thus North Korea's "de facto" head of state. His succession had been foreshadowed in 1980, when he was introduced to the public at the Sixth Party Congress. In 1982, Kim Jong-il had established himself as a leading theoretician with the publication of "On the Juche Idea". In 1984, he had been officially confirmed as his father's successor.
