Thābit

The Banu Thabit, also called the Banu Ammar, were a Berber dynasty of the Huwwara confederation who ruled Tripoli in the fourteenth century. Their founder Thabit ibn Ammar seized the city around 1324 but was murdered within months; his son Muhammad took command in 1326 or 1327 and governed almost independently of Tunis until he was assassinated around 1348.

Muhammad's son Thabit lost the city to a Genoese expedition in 1354 or 1355 and was killed soon after. The surviving family fled to Alexandria, prospered as merchants, and used their fortune to return and retake Tripoli in 1369 or 1370 under Abu Bakr.

His nephew Ali then ruled until the Hafsid sultan Abu Faris Abd al-Aziz II arrested him and reconquered the city in 1401, ending the dynasty and bringing Tripoli back under direct Tunisian rule.
