Hafsid dynasty
The national flag of Tunisia is predominantly red and consists of a white circle in the middle containing a red crescent around a five-pointed star. The Hafsid dynasty used a similar flag during the Middle Ages, it consisted of a white crescent pointing upwards and a white five-pointed star but instead of featuring the red color it featured the yellow color. The crescent and star might also recall the Ottoman flag as an indication of Tunisia's history as a part of the Ottoman Empire.
