The flag of South Korea, or Taegukgi (Although revise official Romanization is Taegeukgi, the word Taegukgi has been used in English-speaking countries historically) has three parts: a white background; a red and blue taegeuk in the center; and four black trigrams, one in each corner of the flag. The flag was designed by Bak Yeong-hyo, the Korean ambassador to Japan. King Gojong proclaimed the Taegeukgi to be the official flag of Korea on 6 March 1883.
