Islamic Tripolitania and Cyrenaica

Islamic rule in Tripolitania and Cyrenaica began as early as the 7th century. With tenuous Byzantine control over Libya restricted to a few poorly defended coastal strongholds, the Arab invaders who first crossed into Pentapolis, Cyrenaica in September 642 encountered little resistance. Under the command of Amr ibn al-A'as, the armies of Islam conquered Cyrenaica, renaming the Pentapolis, Barqa.
