The Flag of North Korea was adopted on September 8, 1948, as the national flag and ensign. The red star of Communism can be seen on this flag on a white disk. North Korea had originally adopted a "taegeugki" following independence from the Japanese Empire with a taoist yin-yang symbol similar to that in the South Korean flag but later revised its flag to more closely reflect that of the USSR.

The colour red represents revolutionary patriotism. The blue stripes connote "The aspiration of the Korean people to unite with the revolutionary people of the whole world and fight for the victory of the idea of independence, friendship and peace."
