The North Korean flag's prominent motif is a red star, which is a universal symbol of communism and socialism, although since the flag's adoption the application of the Marxist-Leninist-natured philosophy of "Juche" has replaced communist authority as the state's guiding ideology, and references to communism have been systematically removed from the country's constitution and legal documents. However, the constitution is still stated to be socialist in nature. Despite the many changes to the constitution, the description of the flag has always remained the same.
