North Korea
Kim Jong-un of the Kim dynasty is the current Supreme Leader or "Suryeong" of North Korea. He heads all major governing structures: he is Chairman of the Workers' Party of Korea, Chairman of the State Affairs Commission of North Korea, and Supreme Commander of the Korean People's Army. His grandfather Kim Il-sung, the founder and leader of North Korea until his death in 1994, is the country's "Eternal President", while his father Kim Jong-il who succeeded Kim Il-sung as leader was announced "Eternal General Secretary" after his death in 2011.
Kim Il-sung
In December 1945, the Soviets installed Kim as chairman of the North Korean branch of the Korean Communist Party. Originally, the Soviets preferred Cho Man-sik to lead a popular front government, but Cho refused to support a UN-backed trusteeship and clashed with Kim. General Terentii Shtykov who led the Soviet occupation of northern Korea, supported Kim over Pak Hon-yong to lead the Provisional People's Committee for North Korea on 8 February 1946. As chairman of the committee, Kim was "the top Korean administrative leader in the North," though he was still "de facto" subordinate to General Shtykov until the Chinese intervention in the Korean War.
