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.
List of leaders of North Korea
Kim Il-sung died on 8 July 1994, but has since 1998 been posthumously named the "Eternal President of the Republic". Thus his son and successor as leader, the late Kim Jong-il, was not given the title of President and the President of the Presidium of the Supreme People's Assembly became "de jure" head of state.
