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.
Fifth Republic of Korea
The Fifth Republic of South Korea was the government of South Korea from 1981 to 1987, replacing the Fourth Republic of South Korea. Throughout this period, the government was controlled by Chun Doo-hwan, a military colleague of the assassinated president Park Chung-hee. This period saw extensive efforts at reform. It laid the foundations for the relatively stable democratic system of the subsequent Sixth Republic in 1987.
