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.
National Liberation Day of Korea
The National Liberation Day of Korea is a holiday celebrated annually on August 15 in both North and South Korea. It commemorates Victory over Japan Day, when U.S. and Soviet forces ended the decades-long Japanese occupation of Korea. It is notable for being the only Korean public holiday celebrated by both North and South Korea.
