Byzantine Italy
Byzantine Italy consisted of various parts of the Italian peninsula that were under the control of the Byzantine Empire since the Gothic War (535–554), and up to the end of the 11th century, with a brief attempt of Byzantine reconquest in the middle of the 12th century.
Chronologically, it refers to:
- Praetorian prefecture of Italy (540/554–584)
- Exarchate of Ravenna (584–751)
- Theme of Sicily (687–902)
- Theme of Longobardia (c. 891 – c. 965)
- Catepanate of Italy (965–1071)
Several states avoided conquest by the Lombards or Franks and maintained nominal Byzantine allegiance even after the Byzantine presence in Italy came to an end:
- Byzantine Venetia (later: Republic of Venice)
- Duchy of Naples
- Duchy of Gaeta
- Duchy of Amalfi
- Duchy of Sorrento
Likewise, the island of Sardinia maintained Byzantine allegiance in this period:
