Muhammad I Abu 'l-Abbas

Abū ʾ l - ʿ Abbās I. Muhammad ibn al - Aghlab Arabic أبو العباس محمد بن الأغلب, DMG Abū ʾ l - ʿ Abbās Muḥammad b. al - Aġlab († 856) was fifth Emir of Aghlabids in Ifriqiya ( 841-856 )

Abū ʾ l - ʿ Abbās I. Muhammad was the son of Abū ʿ Iqāl ( 838-841 ) in Ifriqiya to power. Under him, the expansion of Aghlabids in the Mediterranean reached a climax. So Messina was captured in Sicily (843 ) and Taranto and Bari ( 841 ) in Apulia. Even Rome was attacked by the Muslims and the Vatican plundered 846 ( this was at that time outside of Rome). However, it was also the first setbacks, as a renewed attack on Rome 849 at the Battle of Ostia failed. The Aghlabids increasingly lost control of the Muslim conquests in Italy. So declared the Muslims in Taranto ( 847-880 ) and Bari ( 847-871 ) their independence and set up their Emirates directly to the Caliph of the Abbasids in Baghdad.

In Ifriqiya even the economy continued to boom and the trade took a sharp upturn. So agriculture was promoted through the development of Roman irrigation systems or their new on. Under Abū ʾ l - ʿ Abbās Muhammad I were, inter alia, the great mosques of Sousse and Sfax built. Successor of Muhammad I was his nephew Abū Ibrāhīm Ahmad ( 856-863 ), under whom the empire reached its peak.
