Muslim conquest of Sicily
The Muslim Aghlabids conquered Sicily between June 827 and 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 Arab Muslim rule until it was conquered in turn by the Normans in the late 11th century.
