The island was originally colonised by the Carians. A contingent from Kos participated in the War of Troy The Dorians invaded it in the 11th century BC, establishing a Dorian colony with a large contingent of settlers from Epidaurus, whose Asclepius cult made their new home famous for its sanatoria. The other chief sources of the island's wealth lay in its wines and, in later days, in its silk manufacture. Its early history–as part of the religious-political amphictyony that included Lindos, Kamiros, Ialysos, Cnidus and Halicarnassus, the Dorian Hexapolis (Greek for six cities), is obscure. At the end of the 6th century, Kos fell under Achaemenid domination but rebelled after the Greek victory at Cape Mykale in 479. During the Greco-Persian Wars, when it twice expelled the Persians, it was ruled by tyrants, but as a rule it seems to have been under oligarchic government. In the 5th century, it joined the Delian League, and, after the revolt of Rhodes, it served as the chief Athenian station in the south-eastern Aegean (411–407). In 366 BC, a democracy was instituted.
