History

How the flag of South Korea got here

1882

A flag for the American treaty

May 1882 → Sept 1882

Asked by the American side for a national flag, Kim Hong-jip had the interpreter Lee Eung-jun draw a taegeuk flag aboard ship, and it was used at the signing of the treaty with the United States in May 1882.

1882
The four-trigram flag

1883
Flag of Joseon and the Korean Empire

Flag of Joseon and the Korean Empire

6 Mar 1883 → 1910

Proclaimed the national flag by royal order, without construction rules, so it was drawn in many forms. The Korean Empire kept it from 1897.

1910
The flag of the independence movement

1910 → 15 Aug 1945

Banned under Japanese rule, it was carried in the March First Movement of 1919 and used by the Provisional Government in China, which began calling it the national flag in 1942 and issued a style guide on 29 June 1942.

1945
