North Korea Flag
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 disc. The flag of North Korea was adopted in 1948, when Northern portion of Korea became a Communist state. The traditional Korean flag was red, white, and blue. The country retained these colours (with more prominence given to the red) and added a red star on a white disk. The disk recalls the taegeuk found on the flag of South Korea, and represents the opposing principles of nature. The red stripe expresses revolutionary traditions; the red star is for Communism. The two blue stripes stand for sovereignty, peace and friendship. The white stripes symbolize purity. Wikipedia
