According to Herodotus, the island was initially called Strongyle (the Round One). Then later, because of its beauty, it was named Kalliste (the Fairest One). The Phoenicians settled in Kalliste, and after the Phoenicians, the Lacedaemonians arrived and renamed the island after their leader, Theras. In the 9th century B.C. Thera, became an important stopping point of that era in the travel routes between the East and the West. The Phoenician alphabet was adopted at this time for writing in the Greek language. Interestingly though, the conservative Therans, did not follow the cultural development of their counterparts in the other Cycladic islands. At about 630 B.C the Therans reached the north coast of the African continent where they founded Cyrene, the only Theran colony. From as early on as the 6th century B.C. Thera had its own coinage. During the Classical period in Greece [5th and 4th century B.C.] Thera did not play any significant role in the events of that Hellenic time. During the Peloponesian War Thera sided with Sparta, as expected. In Hellenistic times the island's strategic position made Thera an important base for the war campaigns in the Aegean of the successors to Alexander the Great.
