Meaning of the Turkish flag

Meaning of flags is a difficult topic, especially when flags are very ancient. There is usually sparse historical evidence and a lot of legends. Moreover, individuals may have their own interpretation of their national flag. Concerning Turkey, I found the following in the authoritative books of W. Smith ([smi75c] & [smi80]):

Historical facts:

Red has been prominent in Turkish flags for 700 years. The star and crescent are Muslim symbols, but also have a long pre-Islamic past in Asia Minor. The basic form of the national flag was apparently established in 1793 under Sultan Selim III, when the green flags used by the navy were changed to red and a white crescent and multipointed star were added. The five-pointed star dates from approximately 1844. Except for the issuance of design specifications, no change was made when the Ottoman Empire became the Republic of Turkey and the Caliphate (religious authority) was terminated. Many traditions explain the star and crescent symbol. It is known that Diana was the patron goddess of Byzantium and that her symbol was a moon. In 330, the Emperor Constantine rededicated the city - which he called Constantinople - to the Virgin Mary, whose star symbol was superimposed over the crescent. In 1453 Constantinople was captured by the Ottoman Turks and renamed Istanbul, but its new rulers may have adopted the existing emblem for their own use.


A reflection of the moon occulting a star, appearing in pools of blood after the battle of Kosovo in 1448*, led to the adoption of the Turkish flag by Sultan Murad II according to one legend. Others refer to a dream of the first Ottoman Emperor in which a crescent and star appeared from his chest and expanded, presaging the dynasty's seizure of Constantinople. At least three other legends explain the flag.

*There was a "Second Kosovo War", which is as popular as the first one from the perspective of Ottoman history, and the year 1448 refers to this war. This war continued for only two days (17-19 October 1448) and it was in the time of Sultan Murat II, unlike the first war (which was during the rule of Sultan Murat I). The resources refer the second war as a bloody war, which supports the legend of the origin of Turkish flag.

Nicknames of the flag

Turkish people call their national flag ay yildiz (moon star).

Resat Erel, 20 June 1999

Ayyildiz is also the name of a Turkish city at approx. 36.80 latitude, 37.73 longitude.

Another nickname for the flag is al sancak, which translates into "red banner". Besides, sancak has its unique meaning in Turkish and cannot be directly translated into English, but the nearest to that is the "banner".

Cem Kenan Magripli, 28 January 2004

I think "red banner" is a good translation for al sancak. I think this nickname for the Turkish flag comes from the words of the Turkish national anthem Istiklal Marsi. The poet of national anthem, Mehmet Akif Ersoy, used this metaphor for the flag.

Coming to the translation, sancak is defined as "banner", "flag" or "standard" in Turkish-English dictionaries that I've looked up. The Turkish definition of sancak is "flag carried by military unit, usually having writings, fringe and pole". Today, I think it corresponds to "banner", however its meaning when it was first used could be different and can mean any flag.

The very same word was used in Ottoman times for an administrative unit (see also Sandžak in Serbia and Montenegro). but is does not correspond to any administrative division in Turkey any more.

Onur Özgün, 28 January 2004

As I understood, the administrative unit was named sancak after it being ruled by a ruler who had right and duty to maintain a military unit that carried his flag , i.e. a (territoirial) sancak would provide one unit with a flag.

Construction sheet for the Turkish flag

Construction sheet

Construction sheet for the flag of Turkey - Image by Željko Heimer

The construction sheet is given in a book on Turkish flags [kur92].
The book is in Turkish, 170 pages, with some 30 colour plates of historical and current flags and some black and white photos. It might be that the construction is taken from the flag law which is quoted in full in the book.

The above image is based on the construction sheet in the book, adapted slightly to make it better looking as a digital image. The base unit is the flag width and other dimensions are expressed through it. The center of the circle forming the crescent is half flag width from the hoist, with diameter of the same (i.e. radius 1/4 as indicated on the image). The inner circle forming the crescent has a radius of 1/5 and is offset towards the fly 0.0625 (1/16) [the book actually give number 0.625 here, but that must be printing error as it would make no sense!]. The two circles intersect, forming the "indentation" of the crescent to be 1/3. The five-pointed star is inscribed in a circle with diameter 1/4, tangential to the line connecting the intersections of the two circles. The construction sheet also gives the width of the white heading on hoist (not shown on the image) as 1/30 of the flag width.

Željko Heimer, 2 March 1999

In a book on Turkish flags [vht94] issued by the VDCN (March 1994) is the same construction sheet. In the accompanying table, the white heading on hoist is given as "Width of the seam band".

Mark Sensen, 8 March 1999

The very same construction sheet already appeared in the Flaggenbuch (1939-1941) [neu92]
