The Aeolians (/iːˈoʊliənz/; Greek: Αἰολεῖς) were one of the four major tribes in which Greeks divided themselves in the ancient period (along with the Achaeans, Dorians and Ionians). […]

Their name mythologically derives from Aeolus, the mythical ancestor of the Aeolic branch and son of Hellen, the mythical patriarch of the Greek nation. It actually comes from Greek aiolos meaning “quickly moving”.[1] The dialect of ancient Greek they spoke is referred to as Aeolic. […]

According to Herodotus, the Aeolians were previously called Pelasgians.[2]
