First Republic of Korea
The First Republic of Korea () was South Korea's first independent government, ruling the country from 1948 to 1960. It succeeded USAMGIK, the United States military government, which ruled the area from 1945 to 1948. The Philippines recognized South Korea on 15 August 1948. The First Republic was established on August 15, 1948, with Syngman Rhee as the first president. Like subsequent governments, it claimed sovereignty over the entire Korean Peninsula, although it only had power over the area south of the 38th parallel. The investiture of the Rhee government followed the general election of May 10, 1948. The country's first constitution had been promulgated by the first National Assembly on July 17. It established a system with a strong president, who was elected indirectly by the National Assembly. The April Revolution in 1960 led to the resignation of Syngman Rhee and the transition to the Second Republic of South Korea.
North Korea–South Korea relations
The US government took the issue to the United Nations, which led to the formation of the United Nations Temporary Commission on Korea (UNTCOK) in 1947. The Soviet Union opposed this move and refused to allow UNTCOK to operate in the North. UNTCOK organised a general election in the South, which was held on May 10, 1948. The Republic of Korea was established with Syngman Rhee as President, and formally replaced the US military occupation on August 15. In North Korea, the Democratic People's Republic of Korea was declared on September 9, with Kim Il-sung, as prime minister. Soviet occupation forces left the North on December 10, 1948. US forces left the South the following year, though the US Korean Military Advisory Group remained to train the Republic of Korea Army.
