The Ionian League (also called the Panionic League) was a confederacy formed as early as
800 BC comprising 12
Ionian cities. These were listed by
Herodotus (I.142) as
Miletus,
Myus, and
Priene, all in
Caria (a region in
Asia Minor) and speaking the same dialect;
Ephesus,
Colophon,
Lebedus,
Teos,
Clazomenae and
Phocaea, in
Lydia and-or the region known today as
Ionia (both also in Asia Minor, Lydia extending inland much farther relative to Ionia), speaking another dialect;
Chios (island) and
Erythrae (Asia Minor), with a common dialect; and
Samos (island), with its own dialect. Later,
Smyrna joined, though the city antedated the
Ionian colonizations.
