Emirate of Sicily Emirate of Sicily The Emirate of Sicily () was an emirate on the island of Sicily which existed from 831 to 1091. Its capital was Palermo. Muslim Moors, who first conquered in 652, seized control of the entire island from the Byzantine Empire in a prolonged series of conflicts from 827 to 902. An Arab-Byzantine culture developed, producing a multiconfessional and multilingual state. The Emirate was conquered by Christian Norman mercenaries under Roger I of Sicily, who founded the County of Sicily in 1071. The last Muslim city in the island, Noto, was conquered in 1091. Sicilian Muslims remained citizens
Sicily in 552. In 535, Emperor Justinian I made Sicily a Byzantine province and, as in Roman times, Greek continued to be the predominate language spoken on the island. After the advent of Islam, Sicily was invaded by the Arab forces of Caliph Uthman in 652, but the Arabs failed to make any permanent gains and returned to Syria after gathering some booty. Raids seeking loot continued until the mid-8th century. Byzantine Emperor Constans II decided to move from the capital Constantinople to Syracuse in Sicily during 660. The following year, he launched an assault from Sicily against the Lombard Duchy
