The capture of Syracuse marked a pivotal moment in the Aghlabid campaigns in Sicily. The siege began as the Aghlabids aimed to solidify their control over the island, which was an important strategic point in the Mediterranean. Syracuse, known for its formidable defenses and historical significance, was a target due to its wealth and position. The Aghlabids, led by Ahmad ibn Qurhub, implemented a siege strategy that included the construction of siege works and the blockade of supply routes to weaken the defenders' morale and resources.

Throughout the nine-month siege, the defenders of Syracuse faced increasingly dire conditions as their food supplies dwindled and morale declined. The Aghlabids employed various tactics, including direct assaults and psychological warfare, to further destabilize the city’s defenses. The siege culminated in the eventual breach of the city walls, allowing Aghlabid forces to enter and seize control. This victory not only demonstrated the military prowess of the Aghlabids but also facilitated their larger agenda of Islamic expansion in the Mediterranean region.

Following the capture of Syracuse, the Aghlabids swiftly moved to establish their rule, which included the imposition of Islamic governance and culture on the local populace. The fall of this important city contributed to the decline of Byzantine influence in Sicily and the eventual establishment of a Muslim presence that would last for centuries. The incorporation of Syracuse into the Aghlabid realm allowed for increased trade and cultural exchanges between the Islamic world and Europe, altering the historical trajectory of the region significantly.
