Another important expansion took place under the Greeks of Pontos who came there around 300 BC and developed the city as a trading center for the commerce of goods between the Black Sea ports and Crimea to the north; Assyria, Cyprus, and Lebanon to the south; and Georgia, Armenia and Persia to the east. By that time the city also took its name Ἄγκυρα (''Ánkyra'', meaning ''anchor'' in Greek) which, in slightly modified form, provides the modern name of ''Ankara''.
