PAN: 186C RGB: 227, 10, 23 HEX: #E30A17 </Td> </Tr> <P> The flag of Turkey (Turkish: Türk bayrağı) is a red flag featuring a white star and crescent . The flag is often called al bayrak (the red flag), and is referred to as al sancak (the red banner) in the Turkish national anthem . The current design of the Turkish flag is directly derived from the late Ottoman flag, which had been adopted in the late 18th century and acquired its final form in 1844 . The measures, geometric proportions, and exact tone of red of the flag of Turkey were legally standardized with the Turkish Flag Law on May 29, 1936 . </P> <P> The pre-modern Ottoman armies used the horse - tail standard or tugh rather than flags . Such standards remained in use alongside flags until the 19th century . A depiction of a tugh is found in the Relation d'un voyage du Levant by Joseph Pitton de Tournefort (1718). War flags came into use by the 16th century . During the 16th and 17th centuries, Ottoman war flags often depicted the bifurcated Zulfiqar sword, often misinterpreted in Western literature as showing a pair of scissors . A Zulfiqar flag claimed to have been used by Selim I (d . 1520) is on exhibit in the Topkapı Museum . Two Zulfiqar flags are also depicted in a plate dedicated to Turkish flags in vol. 7 of Bernard Picart's Cérémonies et coutumes religieuses de tous les peuples du monde (1737), attributed to the Janissaries and the Ottoman cavalry . The crescent symbol appears in flags attributed to Tunis from as early as the 14th century (Libro de conoscimiento), long before Tunis fell under Ottoman rule in 1574 . The Spanish Navy Museum in Madrid shows two Ottoman naval flags dated 1613; both are swallow - tailed, one green with a white crescent near the hoist, the other white with two red stripes near the edges of the flag and a red crescent near the hoist . </P>
