The Tunisian flag is a red field with a centered white sun and in the sun a red star and crescent. The used colors in the flag are red, white. The proportion of the Tunisian flag is 2:3. The Flag of Tunisia was adopted in 1831. The first use of the current flag design was in 1831. The last change to the current Tunisian flag design was in 1999.
The red and white flag of Tunisia, adopted as the national flag in 1827, has its origins in the naval ensign of the Kingdom of Tunis adopted in 1831 by Al-Husayn II ibn Mahmud. The current official design dates to 1999.
Until the mid-18th century, the design and significance of maritime flags flying on ships in Tunis are unknown. However, various sources have been able to distinguish certain similarities among the flags: they were designed with a crescent-oriented shape in the presence of the colors blue, green, red, and white. Thereafter, and until the early 19th century, the flag was composed of horizontal blue, red and green stripes, identifying the Ottoman regency in Tunis. This kind of flag with multiple bands and irregular contours floated on top of ships all along the coast of North Africa; similar flags with different colors and arrangements were also used on the continent.
According to Ottfried Neubecker, the Bey of Tunis also had his own flag. This flag was most likely a simple personal banner of the ruler, as it floated above the Bardo Palace, the Citadel of Tunis, on navy ships, and also in the center of the coat of arms in Tunisia. It was used at a number of public ceremonies—including at the proclamation of the Ottoman constitution on 21 March 1840—until the abolition of the Bey monarchy on 25 July 1957.
Believed to have been introduced by Al-Husayn II ibn Mahmud, although some sources, such as Abdel-Wahab, claim that it was in use three centuries earlier, the flag was rectangular in shape and divided into nine stripes, the middle one green and double the size of all other bands, while the others alternated between yellow and red. Featured in the center of the green stripe was the Zulfiqar, the legendary Islamic sword of Ali, with the blade in white and the hilt multicolored. The red and yellow stripes each contained five equidistant symbols, whose order was alternated between each stripe. These symbols were divided into two categories: one red six-sided star voided with a disk of a different color in the center—either a red star and green disk or a white star and blue disk—, and a large disk voided in its lower right by a small disk of different color, with the combination being either a small red disk within a larger blue disk or a small yellow disk within a larger green disk. The first yellow stripe contains three red stars and two blue disks. The second stripe, red in color, contains three green disksand two white stars. The third stripe (second yellow one) is identical to the first, with the exception that the star in its center is white, while the fourth stripe (second white one) is identical to the 2nd stripe
