List of leaders of North Korea
At the end of World War II, Soviet Union occupied the northern half of Korea and in 1946 established the Provisional People's Committee for North Korea chaired by Kim Il-sung. On 9 September 1948, the DPRK was proclaimed, also led by Kim Il-sung.
Division of Korea
With the onset of the Cold War, negotiations between the United States and the Soviet Union failed to lead to an independent and unified Korea. In 1948, UN-supervised elections were held in the US-occupied south only. Syngman Rhee won the election while Kim Il-sung was appointed as the leader of North Korea. This led to the establishment of the Republic of Korea in South Korea, which was promptly followed by the establishment of the Democratic People's Republic of Korea in North Korea. The United States supported the South, the Soviet Union supported the North, and each government claimed sovereignty over the whole Korean peninsula.
