List of ambassadors of the United States to South Korea
At the end of World War II, American forces accepted Imperial Japan's surrender in southern Korea, and Soviet forces accepted the surrender of the Japanese in northern Korea. Talks to agree upon a unity government for Korea failed and in 1948, two separate Korean states were created: the Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea). The United States established diplomatic relations with the new South Korean government, but did not recognize North Korea. Other countries, like the Soviet Union, recognized the Pyongyang government in North Korea, but did not initially establish relations with the South Korean government in Seoul.
Constitution of South Korea
The Constitution declares South Korea a "democratic republic" (taken from Article 1 of Constitutional Charter of the Provisional Government of the Republic of Korea of 1919), its territory consisting of "the Korean Peninsula and its adjacent islands," and that "The Republic of Korea shall seek unification and shall formulate and carry out a policy of peaceful unification based on the principles of freedom and democracy." There are disputes over what "freedom and democracy" mean in Korea, but the direct translation of the Korean word used in the constitution (자유민주적 기본질서) would be liberal democracy.
