The chief cleruchies of Pericles are: Thracian Chersonese (453-452), Lemnos and Imbros, Andros, Naxos and Eretria (before 447); ' Brea in Thrace (446); Oreus (445); Amisus and Astacus in the Black Sea (after 440); Aegina (431).
The following are the chief islands: - Thasos, in the extreme north, off the Macedonian coast; Samothrace, fronting the Gulf of Saros; Imbros and Lemnos, in prolongation of the peninsula of Gallipoli (Thracian Chersonese); Euboea, the largest of all, lying close along the east coast of Greece; the Northern Sporades, including Sciathos, Scopelos and Halonesos, running out from the southern extremity of the Thessalian coast, and Scyros, with its satellites, north-east of Euboea; Lesbos and Chios; Samos and Nikaria; Cos, with Calymnos to the north; all off Asia Minor, with the many other islands of the Sporades; and, finally, the great group of the Cyclades, of which the largest are Andros and Tenos, Naxos and Paros.
In 1686 the colony submitted to Sir Edmund Andros, who had been commissioned governor of all New England, and chose representatives to sit in his council.
When Antigonus Gonatas threatened to restore Macedonian power in Greece, the Athenians, supported perhaps by the king of Egypt, formed a large defensive coalition; but in the ensuing " Chremonidean War " (266-263) a naval defeat off Andros led to their surrender and the imposition of a Macedonian garrison.
Its control of the Aegean was, however, contested not without success by the Antigonids, who won the two great sea-fights of Cos (c. 256) and Andros (227), and wrested the overlordship of the Cyclades from the Ptolemies.
