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.
Provisional People's Committee of North Korea
On 8-9 February 1946, a meeting of political parties, social organizations, people's committees and administrative bureaus in northern Korea established the Provisional People's Committee of North Korea. This new communist-dominated committee was headed by its chairman Kim Il-sung, a communist being backed by the Soviets to become the North Korean leader. This committee effectively became a de facto provisional government that carried out reforms in northern Korea such as land reforms and nationalization of key industries in accordance to the 20-Point Platform issued by Kim Il-sung in March 1946. The Soviet Civil Administration continued to function concurrently with the Provisional People's Committee of North Korea, but in an advisory role.
