Oea (/ˈiːə/; Ancient Greek: Ἐώα[1]) was an ancient city in present-day Tripoli, Libya. It was founded by the Phoenicians in the 7th century BC and later became a Roman–Berber colony.[2] As part of the Roman Africa Nova province, Oea and surrounding Tripolitania were prosperous. It reached its height in the 2nd and 3rd centuries AD, when the city experienced a golden age under the Severan dynasty in nearby Leptis Magna.[3] The city was conquered by the Rashidun Caliphate with the spread of Islam in the 7th century and came to be known as Tripoli during the 9th century.
