Modern Greek island group off the west coast of
Greece, stretching south from the Albanian coast to the southern tip of the Peloponnese, and often called Heptanesos ("Seven Islands").
The Ionian islands are Corfu (Kerkira), Cephalonia (Kefallonia), Zakynthos (Zakinthos, Zante), Lefkada (Lefkas), Ithaca (Ithaki), Kithira, and Paxos (Paxoí), with their minor dependencies. Their combined land area is 2,307 square km. With good rainfall and much arable soil, the
Ionian islands produce timber, fruit, and flax and raise pigs, sheep, and goats. Their exports include currants, wine, cotton, salt, olives, and fish, and the islands are largely self-sufficient in grains. Their harbours are superior to those of the west coast of
Greece and more conveniently located for international shipping.
Because of their strategic maritime location between the Greek and Italian mainlands, intervention from outside has affected the islands and their people since classical times. Leo IV the Wise (c. AD 890) formed most or all of the islands into a province of the Byzantine Empire as the theme of Kefalonia. The Norman adventurer Robert Guiscard captured Corfu (1081) and Kephalonia, but his death (1085) prevented the establishment of a dynasty. When the Latin empire (1204-61) was established at Konstantinople, the Venetians received Corfu, but in 1214 the Greek despotate of
Epirus annexed the first Venetian colony, and a long period of Epirote, Sicilian, and Neapolitan-Angevin rule followed until 1386, when Corfu submitted voluntarily to the Venetian republic. In 1479 the Turks captured the islands of Kefalonia, Zakinthos, Lefkada, and Ithaka, annexing them to their empire. The Venetians soon counterattacked and retook them during the 15th and 16th centuries.
