The Aghlabids built several architectural landmarks in Kairouan, Monastir, Sousse and Tunis. Ifriqiya became the main link for trade between the East and West, and between al-Andalus and the Sudan. Ifriqiya’s agricultural and other industries, such as textile weaving and ceramics, prospered. The downfall of the Aghlabids was due mainly to the frivolity and profligacy which dominated the rule of Ziyadat Allah III (290–6 / 903–9), which prompted the people of Ifriqiya to withdraw their support, and led in turn to the fall of Ifriqiya – with no resistance – to the Fatimids.
