The County of Sicily was a Norman feudal state comprising the islands of Sicily and Malta from 1071 until 1345. The county began to form during the Christian reconquest of Sicily (1061–91) from the Muslim Emirate, established by conquest in 965. The county is thus a transitionary period in the history of Sicily. After the Muslims had been defeated and either forced out or incorporated into the Norman military, a further period of transition took place for the county and the Sicilians.
