After the fall of Carthage the Romans did not occupy immediately Tripolitania (the region around Tripoli), but left it under control of the Berber kings of Numidia, until the coastal cities asked and obtained its protection. Ptolemy Apion, the last Greek ruler, bequeathed Cyrenaica to Rome, which formally annexed the region in 74 BCE and joined it to Crete as a Roman province. During the Roman civil wars Tripolitania (still not formally annexed) and Cyrenaica sustained Pompey and Marc Antony against respectively Caesar and Octavian. The Romans completed the conquest of the region under Augustus, occupying northern Fezzan ("Fasania") with Cornelius Balbus Minor. As part of the Africa Nova province, Tripolitania was prosperous, and reached a golden age in the 2nd and 3rd centuries, when the city of Leptis Magna, home to the Severan dynasty, was at its height. On the other side, Cyrenaica's first Christian communities were established by the time of the Emperor Claudius but was heavily devastated during the Kitos War and almost depopulated of Greeks and Jews alike, and, although repopulated by Trajan with military colonies, from then started its decadence.
