在朝鮮アメリカ陸軍司令部軍政庁
Following the war, the United States and the United Kingdom used military forces in Greece and Korea to remove indigenous governments and forces seen as communist. Under the leadership of Lyuh Woon-Hyung, working secretly during the Japanese occupation, committees throughout Korea formed to coordinate the transition to Korean independence. Following the Japanese surrender, on August 28, 1945, these committees formed the temporary national government of Korea, naming it the People's Republic of Korea (PRK) a couple of weeks later. On September 8, 1945, the United States government landed forces in Korea and thereafter established the United States Army Military Government in Korea (USAMGK) to govern Korea south of the 38th parallel north. The USAMGK outlawed the PRK government. The military governor Lieutenant-General John R. Hodge later said that "one of our missions was to break down this Communist government." Thereafter, starting with President Syngman Rhee, the U.S supported authoritarian South Korean governments, which reigned until the 1980s.
