Ban Ki-moon is a South Korean politician and diplomat who served as the eighth secretary-general of the United Nations between 2007 and 2016. Prior to his appointment as secretary-general, Ban was the South Korean Minister of Foreign Affairs and Trade between 2004 and 2006. Ban was initially considered to be a long shot for the office of Secretary-General of the United Nations; he began to campaign for the office in February 2006. As the foreign minister of South Korea, he was able to travel to all the countries on the United Nations Security Council, a manoeuvre that subsequently turned him into the campaign's front-runner.

Ban was born on 13 June 1944 in the small farming village of Haengchi, Wonnam Township (-myeon), in Insei, Chūseihoku-dō, Korea, Empire of Japan (now North Chungcheong Province, South Korea). He is of the Gwangju Ban clan. His family then moved to the nearby town of Chungju, where he grew up. During Ban's childhood, his father had a warehouse business, but the warehouse went bankrupt and the family lost its middle-class standard of living. When Ban was six, his family fled to a remote mountainside for much of the Korean War. After the war ended, his family returned to Chungju. Ban has said that, during this time, he met American soldiers.
