The crescent moon and star symbol, present in some flags of Islamic countries, dates back to before the birth of Islam, as far back as the 4th century BC.
Origin – The story of the origin of the crescent moon is not exactly known. But what is certain is that the red crescent was a symbol used by the Persians and Byzantines, and from these peoples it passed directly to the Turks of the Seljuk dynasty of the XI-XIV century and then to the Ottomans. Then, through the Ottomans, the crescent arrived almost unchanged on the flag of present-day Turkey.
Saved by the Moon – However, the origin of the symbol is traced to a special episode that occurred in the 4th century BC, when Byzantium, the future Constantinople, was saved from the siege of Philip II of Macedon thanks to the crescent moon in the sky, which illuminated the attackers .
Muhammad – The Crescent certainly predates the birth of Islam, because the first Muslim communities did not have symbols on their banners. The famous Islamic armies, consisting of 10,000 warriors, at the time of the Prophet Muhammad (570-632), when they conquered Mecca in Saudi Arabia, only waved flags of black, green or white colors to distinguish themselves.
