The County of Sicily, also known as County of Sicily and Calabria, was a Norman state comprising the islands of Sicily and Malta and part of Calabria from 1071 until 1130. 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 transitional 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.

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.
