The Turkish national flag colour for centuries has been red, and ships from Tunisia, like private vessels throughout the Ottoman Empire, flew red ensigns. The current Tunisian national flag, established in 1835, contains a crescent and star on a white disk, also long used by the Turks. The history of those symbols is more ancient than the Ottoman Empire, however. Many nations and civilizations of the Middle East from the days of the ancient Egyptians and Phoenicians had employed standards with the horns of an ox or a crescent moon of the same shape. The Punic state of Carthage, which had existed in the same area as modern Tunisia, emblazoned the crescent moon on its standards and buildings, although the symbol was not chosen by Tunisia because of that association. The crescent and star have greater cultural than religious symbolism. However, because they have been widely adopted by Muslim countries such as Tunisia, they have developed a strong association with Islam.
When France made Tunisia a protectorate in 1881, Tunisia’s existing flags continued to be used. Likewise, the reestablishment of independence in 1956 and the country’s transformation into a republic the following year did not alter the national flag. There have been many other Tunisian flags over the years, including military colours, holy marabout flags of voyagers, and the personal standard of the ruling beys, who served as regents for the Ottoman emperor.
