Libya's second largest city, Benghazi, has a history which extends from when the city was first inhabited in the 6th century BCE to the present day. Throughout its history, the city has been continuously conquered by different ancient and colonial forces. Ancient Greek colony Modern Benghazi lies in the province of Cyrenaica, an area which was heavily colonised by the Greeks in antiquity. After the war of Othomi in 464-460 BC. the Messenians settled in Naupaktos. In 399 BC, expelled once more by the Spartians, they took final refuge in Euesperides. The Greek city that existed within the modern day boundaries of Benghazi was founded around 525 BC. It was called Euesperides () and Esperis (). It was one of five important cities in Cyrenaica known as the Pentapolis — the other four were the chief city Cyrene, its port Apollonia, Taucheira, and Barca. Euesperides was probably founded by people from Cyrene or Barca on the edge of a lagoon which opened from the sea. At the time, the lagoon may have been deep enough to receive small sailing vessels. The name Euesperides was attributed to the fertility of the area, and gave rise to mythological associations with the garden of Hesperides. The city was located on a raised piece of land opposite what is now the Sidi Abeid graveyard, in the Eastern Benghazi suburb of Sebkha Es-Selmani (Es-Selmani Marsh). Euesperides is first mentioned by ancient sources in Herodotus' account of the revolt of Barca and the Persian expedition to Cyrenaica in c.515 BC; the punitive force sent by the satrap in Egypt conquered most of Cyrenaica and reached "as far west as Euesperides". The oldest coins minted in the city date back to 480 BC. One side of the coin has an engraving of Delphi, whilst the other has an engraving of a silphium plant. Silphium once formed the crux of trade from Cyranaica because of its use as a rich seasoning and as a medicine. Euesperides's coinage suggests that it must have enjoyed an intermittent autonomy from Cyrene in the early 5th century, because Euesperidean coins had their own types, distinct from those of Cyrene with the legend EU(ES). An inscription found in modern Benghazi and dated around the middle of the 4th century BC, shows that the city had a similar constitution to that of Cyrene, with a board of chief magistrates (ephors) and a council of
