It is widely believed that the crescent moon and star is an internationally-recognized symbol of Islam. After all, the symbol is featured on the flags of several Muslim countries and is even part of the official emblem for the International Federation of Red Cross and Red Crescent Societies. The Christians have the cross, the Jews have the star of David, and the Muslims have the crescent moon — or so it is thought. The truth, however, is a little more complicated.

Pre-Islamic Symbol

The use of the crescent moon and star as symbols actually can be pre-dated back by several thousand years. Information on the origins of the symbol are difficult to confirm, but most sources agree that these ancient celestial symbols were in use by the peoples of Central Asia and Siberia in their worship of the sun, moon and sky gods. There are also reports that the crescent moon and star were used to represent the Carthaginian goddess Tanit or the Greek goddess Diana.

The city of Byzantium (later known as Constantinople and Istanbul) adopted the crescent moon as its symbol. According to some evidence, they chose it in honour of the goddess Diana. Other sources indicate that it dates back to a battle in which the Romans defeated the Goths on the first day of a lunar month. In any event, the crescent moon was featured on the city’s flag even before the birth of Eesa (Alayhis Salaam).

Early Muslim Community

The early Muslim community did not really have an acknowledged symbol. During the time of the Prophet Muhammad (peace be upon him), Islamic armies and caravans flew simple solid-coloured flags (generally black, green, or white) for identification purposes. In later generations, the Muslim leaders continued to use a simple black, white or green flag with no markings, writing, or symbolism of any kind.

Ottoman Empire

It wasn’t until the Ottoman Empire that the crescent moon and star became affiliated with the Muslim world. When the Turks conquered Constantinople, or what is today known as Istanbul, in 1453 CE, they adopted the city’s existing flag and symbol. Legend holds that the founder of the Ottoman Empire, Osman Gazi, had a dream in which the crescent moon stretched from one end of the earth to the other. Taking this as a good omen, he chose to keep the crescent and make it the symbol of his dynasty.

There is speculation that the five points on the star represent the five pillars of Islam, and some have been more specific and said the five daily prayers, but this is pure conjecture. The five points were not standard on the Ottoman flags, and are still not standard on flags used in the Muslim world today.

For hundreds of years, the Ottoman Empire ruled over the Muslim world. After centuries of battle with Christian Europe, it is understandable how the symbols of this empire became linked in people’s minds with the faith of Islam as a whole. The heritage of the symbols, however, really is based on links to the Ottoman Empire, not the faith of Islam itself.

Accepted Symbol of Islam?

Based on this history, many Muslims reject the use of the crescent moon as a symbol of Islam. The faith of Islam has historically had no symbol, and many Muslims refuse to accept what they see as essentially an ancient pagan icon. It is certainly not in uniform use among Muslims.

Others prefer to use the Ka’ba, Arabic calligraphy writing, or a simple mosque icon as symbols of the faith.
