The Caspians were a people of antiquity who dwelt along the southwestern shores of the Caspian Sea, in the region known as Caspiane. Caspian is the English version of the Greek ethnonym Kaspioi, mentioned twice by Herodotus among the Achaemenid satrapies of Darius the Great and applied by Strabo. The name is not attested in Old Iranian. According to Vasily Struve, the 'Caspians' was the name given to those Saka-Massagetae tribes that were located along the sea coast.
