Flag of Macedonia may refer to two different flags used in the historic region of Macedonia. Both consist of a yellow sun on a sold-color background. Both bore the Vergina Sun until 1995 when under Greek pressure the Republic's flag replaced the Vergina Sun with its current sun.
The Vergina Sun (Greek Ήλιος της Βεργίνας, also known as the "Star of Vergina", "Macedonian Star" or "Argead Star") is a rayed solar symbol appearing in ancient Greek art of the period between the 6th and 2nd centuries BC. The Vergina Sun proper has sixteen triangular rays, while comparable symbols of the same period variously have sixteen, twelve, eight or (rarely) six rays.
The name "Vergina Sun" became widely used after the archaeological excavations in and around the small town of Vergina, in northern Greece, during the late 1970s. In older references, the name "Argead Star" or "Star of the Argeadai" is used for the Sun as the royal symbol of the Argead dynasty of Macedon. There it was depicted on a golden larnax found in a 4th-century BC royal tomb belonging to either Philip II or Philip III of Macedon, the father and half-brother of Alexander the Great, respectively.
As the historical royal symbol of the ancient kingdom of Macedonia, the Vergina Sun came into popular use among Macedonian Greeks since the 1980s, and became commonly used as an official emblem of the three regional units and the municipalities in the Greek region of Macedonia.
