Hassan ibn al-Nu'man

Hassan ibn al-Nu'man al-Ghassani was an Arab general of the Umayyad Caliphate who led the final Muslim conquest of Ifriqiya, firmly establishing Islamic rule in the region. Appointed by Caliph Abd al-Malik, Hassan launched a series of campaigns during the closing years of the 7th century, during which he defeated the Byzantines and the Berbers led by al-Kahina. The Byzantine capital of Carthage was destroyed in 698 and the nearby city of Tunis was founded in the following year. In Kairouan, Hassan set up a Muslim administration for the province to collect taxes from its Christian inhabitants and pay the troops. He enrolled thousands of Berbers into the army, which proved critical to later Muslim military successes in the Maghreb and the Iberian Peninsula. He was ultimately ousted from his post by the governor of Egypt, Abd al-Aziz ibn Marwan, due to a power struggle for influence over Ifriqiya.
