The Flag of North Korea was adopted on September 8, 1948, as the national flag and ensign. The famous red star of Communism can be seen on this flag on a white disk, which may relate to the yin yang symbol, which is a symbol used in Korean culture.

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."
