Serbian Cross

The Serbian cross with the 4 Cyrillic letters of 'S' (C). If displayed on a field, traditionally it is on red field, but could be used with no field at all.
In Serbian its called cetiri c read s or four c and and the four letters represent the slogan Samo Sloga Srbina Spasava or in english only unity saves the Serbs
The motif of a cross is derived from Constantine's labarum and has figured on Byzantine coins, since the 6th c. Later, the 4 symbols of the cross have been interpreted as flints or firestones, but also as the initials of the imperial motto of the Palaiologos dynasty: King of Kings, Ruling Over Kings.
The cross has been used by Serbian states and the Serbian Orthodox Church since the Middle Ages after Dušan the Mighty was crowned Emperor (Tsar) of the Serbs and Greeks.
Today it is the national, religious and ethnic symbol of Serbs and Serbia.
