Taormina, the last Byzantine stronghold in Sicily, is captured by the Aghlabid army, concluding the Muslim conquest of Sicily.

Taormina is a comune (municipality) in the Metropolitan City of Messina, on the east coast of the island of Sicily, Italy. Taormina has been a tourist destination since the 19th century. Its beaches on the Ionian Sea, including that of Isola Bella, are accessible via an aerial tramway built in 1992, and via highways from Messina in the north and Catania in the south. On 26–27 May 2017 Taormina hosted the 43rd G7 summit.

Sicily, officially the Sicilian Region, is an island in the central Mediterranean Sea and one of the 20 regions of Italy, situated south of the Italian Peninsula in continental Europe. With 4.7 million inhabitants, including 1.2 million in and around the capital city of Palermo, it is both the largest and most populous island in the Mediterranean Sea.

The siege of Taormina in 902 ended the conquest of the Byzantine city of Taormina, in northeastern Sicily, by the Aghlabids. The campaign was led by the deposed Aghlabid emir, Ibrahim II, as a form of armed pilgrimage and holy war. Ibrahim's forces defeated the Byzantine garrison in a hard-fought battle in front of the city walls, and laid siege to the city. Left unsupported by the Byzantine government, Taormina capitulated on 1 August. The population was massacred or sold into slavery. The fall of this last major Byzantine stronghold signalled the completion of the Muslim conquest of Sicily, which had been ongoing since the 820s, although some minor Byzantine outposts survived until the 960s.

The Aghlabid dynasty was an Arab dynasty centered in Ifriqiya from 800 to 909 that conquered parts of Sicily, Southern Italy, and possibly Sardinia, nominally as vassals of the Abbasid Caliphate. The Aghlabids were from the tribe of Banu Tamim and adhered to the Mu'tazilite rationalist doctrine within Hanafi Sunni Islam, which they imposed as the state doctrine of Ifriqiya. They ruled until 909 when they were conquered by the new power of the Fatimids.
