Strategic Narrative Overview
Ja'far opened the siege in August 877 then delegated command to his son Abu Ishaq while withdrawing to Palermo. The Aghlabids deployed effective siege weapons, while the Byzantine fleet — occupied transporting marble for a church in Constantinople and then delayed by storms — provided virtually no relief. The besieged population endured famine and great hardship, vividly recorded by the monk Theodosios, an eyewitness.
01 / The Origins
Having first landed in Sicily in the late 820s, the Aghlabids of North Africa steadily expanded across the western half of the island but repeatedly failed to take Syracuse, the Byzantine capital. In 875 a new, energetic governor, Ja'far ibn Muhammad, was appointed with the express purpose of seizing the city, setting the stage for a determined siege two years later.
03 / The Outcome
On 21 May 878 the Aghlabids breached the seaward walls and stormed the city. The Byzantine patrikios surrendered with a small retinue but was executed a week later; survivors fled east to alert a fleet that had finally sailed but arrived too late. Internal Aghlabid rivalries prevented exploitation of the victory, and small-scale warfare continued until Ibrahim II captured Taormina in 902, effectively completing Muslim rule over Sicily.
