The Emirate of Sicily or Fatimid Sicily was an Islamic kingdom that ruled the Muslim territories on the island of Sicily between 831 and 1091. Its capital was Palermo, which, during this period, became a major cultural and political center of the Muslim world.
Euphemius or Euphemios was a Byzantine commander in Sicily, who rebelled against the imperial governor in 826 AD, and invited the Aghlabids to aid him, thus beginning the Muslim conquest of Sicily.
The history of Islam in Sicily and Southern Italy began with the first Arab settlement in Sicily, at Mazara, which was captured in 827. The subsequent rule of Sicily and Malta started in the 10th century. The Emirate of Sicily lasted from 831 until 1061, and controlled the whole island by 902. Though Sicily was the primary Muslim stronghold in Italy, some temporary footholds, the most substantial of which was the port city of Bari, were established on the mainland peninsula, especially in mainland Southern Italy, though Muslim raids, mainly those of Muhammad I ibn al-Aghlab, reached as far north as Naples, Rome and the northern region of Piedmont. The Arab raids were part of a larger struggle for power in Italy and Europe, with Christian Byzantine, Frankish, Norman and local Italian forces also competing for control. Arabs were sometimes sought as allies by various Christian factions against other factions.
The Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Muslim rule until conquered in turn by the Normans in the 11th century.
The siege of Syracuse in 827–828 marks the first attempt by the Aghlabids to conquer the city of Syracuse in Sicily, then a Byzantine province. The Aghlabid army had only months before landed on Sicily, ostensibly in support of the rebel Byzantine general Euphemius. After defeating local forces and taking the fortress of Mazara, they marched on Syracuse, which was the capital of the island under Roman and Byzantine rule. The siege lasted through the winter of 827–828 and until summer, during which time the besieging forces suffered greatly from lack of food and an outbreak of an epidemic, which claimed the life of their commander, Asad ibn al-Furat. In the face of Byzantine reinforcements, the new Arab leader, Muhammad ibn Abi'l-Jawari, abandoned the siege and withdrew to the southwestern part of the island, which remained in their hands. From there they pursued the slow conquest of Sicily, which led to the fall of Syracuse after another long siege in 877–878, and culminated in the fall of Taormina in 902.
