Demography
Ancient demographics are available only from literary sources. Herodotus states that in Asia the Ionians kept the division into twelve cities that had prevailed in Ionian lands of the north Peloponnese, their former homeland, which became Achaea after they left. These Asian cities were (from south to north) Miletus, Myus, Priene, Ephesus, Colophon, Lebedos, Teos, Erythrae, Clazomenae and Phocaea, together with Samos and Chios. Smyrna, originally an Aeolic colony, was afterwards occupied by Ionians from Colophon, and became an Ionian city — an event which had taken place before the time of Herodotus.
These cities do not match those of Achaea. Moreover, the Achaea of Herodotus' time spoke Doric (Corinthian), but in Homer it is portrayed as being in the kingdom of Mycenae, which most likely spoke Mycenaean Greek, which is not Doric. If the Ionians came from Achaea, they departed during or after the change from East Greek to West Greek there. Mycenaean continued to evolve in a pocket, Arcadia.
There is no record of any people named Ionians in Late Bronze Age Anatolia but Hittite texts record the Achaeans of Ahhiyawa, of location not completely certain, but in touch with the Hittites of that time. Miletus and some other cities founded earlier by non-Greeks received populations of Mycenaean Greeks probably under the name of Achaeans. The tradition of Ionian colonizers from Achaea suggests that they may have been known by both names even then. In the absence of archaeological evidence of discontinuity at Miletus the Achaean population whatever their name appears to have descended to archaic Ionia, which does not exclude the possibility of another colonizing and founding event from Athens.
Herodotus expresses some impatience at the ethnic views of his countrymen concerning Ionia: "for it would be foolishness to say that these are more truly Ionian or better born ...." He lists other ethnic populations among the settlers: Abantes from Euboea, Minyans from Orchomenus, Cadmeians, Dryopians, Phocians, Molossians, Arcadian Pelasgians, Dorians of Epidaurus, and others. The presence of Doric Ionians is somewhat contradictory, but Herodotus himself, a major author of the Ionic dialect, was from a Doric city, Halicarnassus. Even " the best born of the Ionians", the Athenians, married girls from Caria. "Yet since they set more store by the name than the rest of the Ionians, let it be granted that those of pure birth are Ionians."
