 It was the only Yugoslav republic not to use the Pan-Slavic colours on its flag.Macedonia instead adopted an amended version of its previous flag, depicting a gold-edged five-pointed red star in the canton against a red field in a design similar to the flags of the Soviet Union or the People's Republic of China.This flag was adopted on 31 December 1946 under Article 4 of the Constitution of the People's Republic of Macedonia and remained in use until well after Macedonia's independence from Yugoslavia in September 1991, due to lack of agreement about what should replace it.
