"Yunan" is an alternative spelling of "Ionia", an ancient region of central coastal Anatolia in present-day Turkey, historically the northernmost territories of the Ionian League of Greek settlements. Named after the Ionian tribe who in the Archaic Period occupied mainly the shores and islands of the Aegean Sea.

"The cities of Ionia were pioneers of Greek civic (and probably constitutional) development in the 8th and 7th centuries."

"In this period and down to about 500 BC, Ionic rational thought dominated the intellectual life of Greece. [...] The Ionic dialect of Greek became the language of literature and learning, and Ionic architecture, sculpture, and bronze casting were also influential."

"The overseas expansion of Ionia in the 7th century was in part due to the need of a new population outlet after deep Ionic penetrations inland had provoked opposition and conflict with the rising power of Lydia under the Mermnads. After repeated conflicts, most of Ionia finally came under Lydian rule in the reign of Croesus (c. 560-546). After Croesus' fall at the hands of Achaemenian Persia, the cities of Ionia were unable to effectively oppose the latter. The Ionians mounted an unsuccessful revolt against Persian rule in about 499 BC, but their fleet was crushed in a naval battle off Lade five years later. This revolt against the Persians marked the opening phase of the Greco-Persian Wars."

"Under the Roman Empire the principal cities of Ionia experienced a revival of prosperity, and many of the impressive ruins on their sites date from that time. Ephesus, Miletus, Smyrna, and Chios were among the most splendid cities of the Roman world and continued to flourish in Byzantine times."
