Kim Il-sung

Kim Il-sung (1912–1994) was the founder and paramount leader of the Democratic People's Republic of Korea (DPRK). Born Kim Song-ju near Pyongyang during Japanese colonial rule, he became active in anti-Japanese guerrilla activity in Manchuria in the 1930s and spent part of World War II in the Soviet Far East as an officer in the Red Army.

Installed by Soviet occupation authorities in the northern zone of Korea after 1945, he became chairman of the Workers' Party of Korea and, in September 1948, the first premier of the newly proclaimed DPRK. In June 1950 his government launched the invasion of the South that began the Korean War, which ended in the 1953 Armistice Agreement signed at Panmunjom — a ceasefire that, in the absence of a peace treaty, still formally governs inter-Korean relations.

Domestically, Kim consolidated power by purging rival factions (the Soviet-Koreans, Yan'an faction, and the domestic communists) through the 1950s, leaving him unchallenged by the early 1960s. He articulated Juche, an ideology of national self-reliance, which was elevated to state doctrine in the 1972 Socialist Constitution. That constitution also created the post of President, which he held until his death.

Kim pursued a balancing act between the Soviet Union and the People's Republic of China during the Sino-Soviet split, extracting aid from both. He built a pervasive personality cult, with statues, badges, and revised history textbooks centering on his guerrilla record. From the 1970s he groomed his son Kim Jong-il as successor, producing the first hereditary succession in a communist state when he died of a heart attack on 8 July 1994 — weeks before a planned summit with South Korean President Kim Young-sam. In 1998 a constitutional revision named him "Eternal President of the Republic," a posthumous title he still formally holds.
