History of South Korea’s flag
Origins of the Taegeukgi
The Taegeukgi was created in the late 19th century when Korea began increasing diplomatic contact with foreign countries and needed a national flag to represent the state internationally.
The first version of the Taegeukgi appeared in 1882 during the Joseon dynasty. The design featured a red and blue taegeuk symbol in the center with four black trigrams on a white background.
King Gojong officially proclaimed the flag as the national flag of Korea in 1883.
Korean Empire
The Taegeukgi continued to be used after Korea became the Korean Empire in 1897.
The empire remained until the Japanese annexation of Korea in 1910.
Japanese colonial period
During Japanese rule, the Taegeukgi was banned as an official national symbol.
However, it continued to be used by Korean independence activists and by the Korean Provisional Government in exile.
After Korea regained independence following World War II, the Taegeukgi was adopted as the national flag of the Republic of Korea (South Korea) in 1948. North Korea adopted a different national flag in the same year.
Modern standardization
Although the basic design remained consistent, the exact specifications of the Taegeukgi were not fully standardized until the mid-20th century.
In 1949, the South Korean government introduced official rules defining how the flag should be constructed, including the placement of the taegeuk and trigrams.
