A distinct historic region
They are traditionally called the Heptanese, "the Seven Islands" (Greek: Heptanēsa or Italian: Eptaneso), but the group includes many smaller islands as well as the seven principal ones. The Ionian Islands became part of the modern Greek state in 1864.
They date to the centuries-long Venetian rule, which preserved them from becoming part of the Ottoman Empire, and created a distinct cultural identity with many Italian influences
