History of South Korea
On August 15, 1948, the Republic of Korea was formally established, with Rhee Syngman as the first president. With the establishment of Rhee's government, de jure sovereignty also passed into the new government. On September 9, 1948, a communist regime, the Democratic People's Republic of Korea (North Korea), was proclaimed under Kim Il-sung. However, on December 12, 1948, by its resolution 195 in the Third General Assembly, the United Nations recognized the Republic of Korea as the sole legal government of Korea.
Division of Korea
General Abe Nobuyuki, the last Japanese Governor-General of Korea, had established contact with a number of influential Koreans since the beginning of August 1945 to prepare the hand-over of power. Throughout August, Koreans organized people's committee branches for the "Committee for the Preparation of Korean Independence" (CPKI, 조선건국준비위원회), led by Lyuh Woon-hyung, a left-wing politician. On September 6, 1945, a congress of representatives was convened in Seoul and founded the short-lived People's Republic of Korea. In the spirit of consensus, conservative elder statesman Syngman Rhee, who was living in exile in the US, was nominated as President.
