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.
Embassy of South Korea, Washington, D.C.
After the independence of Korea from Japanese rule in 1945, and the founding of South Korea in 1948, South Korea immediately restored normal diplomatic relationship with the United States and has since been sending ambassadors to the United States. Although Chang Myon is officially recorded as the first ambassador serving from February 1949, Chough Pyung-ok was recognized in August 1948 as the Special Representative of the President of South Korea with a personal rank of Ambassador. Chang replaced Chough in January 1949 in the same capacity, and was appointed as the first ambassador the following month.
