Al-Muʿizz ibn Bādīs (Arabic: المعز بن باديس; 1008–1062) was the fourth ruler of the Zirids in Ifriqiya, reigning from 1016 to 1062.
[2] Al-Muizz ascended the throne as a minor following the death of his father Badis ibn Mansur, with his aunt, Umm Mallal, acting as regent.
His son Abdallah shortly ruled Sicily in 1038-1040, after intervening with a Zirid army in the civil war that broke out in the island.
This may have been related to the high level of tribute which the Zirids were compelled to pay annually to the Fatimids (one million gold dinars a year).
The Fatimids dispatched Makin al-Dawla to rally the Bedouin invaders and duly besiege al-Muizz in Kairouan and conquer Gabes and much of Ifriqiya’s hinterlands in 1053–1054.
With the growth of Bedouin Emirates and the continuing insecurity inland, the economy of Ifriqiya looked increasingly towards the Mediterranean, with the result the coastal cities grew in importance through maritime trade and piracy.
