300 BC, though it became more widely used as the royal emblem of Pontic king Mithridates VI Eupator after he incorporated Byzantium into his kingdom for a short period.
[7] Coins with crescent and star symbols represented separately have a longer history, with possible ties to older Mesopotamian iconography.
It rose to prominence with its adoption as the flag and national symbol of the Ottoman Empire and some of its administrative divisions (eyalets and vilayets) and later in the 19th-century Westernizing tanzimat (reforms).
In Late Bronze Age Canaan, star and crescent moon motifs are also found on Moabite name seals.
[13] The depiction of the crescent-and-star or "star inside crescent" as it would later develop in Bosporan Kingdom is difficult to trace to Mesopotamian art.
Exceptionally, a combination of the crescent of Sin with the five-pointed star of Ishtar, with the star placed inside the crescent as in the later Hellenistic-era symbol, placed among numerous other symbols, is found in a boundary stone of Nebuchadnezzar I (12th century BC; found in Nippur by John Henry Haynes in 1896).
[15] An example of such an arrangement is also found in the (highly speculative) reconstruction of a fragmentary stele of Ur-Nammu (Third Dynasty of Ur) discovered in the 1920s.
The combination of the two symbols has been taken as representing Sun and Moon (and by extension Day and Night), the Zoroastrian Mah and Mithra,[19] or deities arising from Greek-Anatolian-Iranian syncretism, the crescent representing Mēn Pharnakou (Μήν Φαρνακου, the local moon god[20]) and the "star" (Sun) representing Ahuramazda (in interpretatio graeca called Zeus Stratios)[21][22] By the late Hellenistic or early Roman period, the star and crescent motif had been associated to some degree with Byzantium.
Hecate was considered the patron goddess of Byzantium because she was said to have saved the city from an attack by Philip of Macedon in 340 BC by the appearance of a bright light in the sky.
[23] Some Byzantine coins of the 1st century BC and later show the head of Artemis with bow and quiver, and feature a crescent with what appears to be a six-rayed star on the reverse.
[31] The crescent and star symbol appears on some coins of the Parthian vassal kingdom of Elymais in the late 1st century AD.
Use of the crescent-and-star combination apparently goes back to the earlier appearance of a star and a crescent on Parthian coins, first under King Orodes II (1st century BC).
[37] Coins from the Western Turkic Khaganate had a crescent moon and a star, which held an important place in the worldview of ancient Turks and other peoples of Central Asia.
[39] Many Crusader seals and coins show the crescent and the star (or blazing Sun) on either side of the ruler's head (as in the Sassanid tradition), e.g. Bohemond III of Antioch, Richard I of England, Raymond VI, Count of Toulouse.
[45] St. Stephen's Cathedral in Vienna used to have at the top of its highest tower a golden crescent with a star; it came to be seen as a symbol of Islam and the Ottoman enemy, which is why it was replaced with a cross in 1686.
[46] In the late 16th century, the Korenić-Neorić Armorial shows a white star and crescent on a red field as the coat of arms of "Illyria".
[52] A decree (buyruldu) from 1793 states that the ships in the Ottoman navy fly that flag, and various other documents from earlier and later years mention its use.
It is mostly derived from the star-and-crescent symbol used by the city of Constantinople in antiquity, possibly by association with the crescent design (without the star) used in Turkish flags since before 1453.
A plate in Webster's Unabridged of 1882 shows the flag with an eight-pointed star labelled "Turkey, Man of war".
Other states in the Ottoman sphere of influence using the star and crescent design in their flats such as Libya (1951, re-introduced 2011) and Algeria (1958).
[2] On February 28, 2017, it was announced by the Qira County government in Hotan Prefecture, Xinjiang, China that those who reported others for stitching the 'star and crescent moon' insignia on their clothing or personal items or having the words 'East Turkestan' on their mobile phone case, purse or other jewelry, would be eligible for cash payments.
