The pressure put on the Western Roman Empire by the Barbarian invasions (notably by the Vandals and Visigoths in Iberia) in the 5th century AD reduced Roman control and led to the establishment of the Vandal Kingdom of North Africa in 430 A.D., with its capital at Carthage. A century later, the Byzantine emperor Justinian I sent (533) a force under General Belisarius that succeeded in destroying the Vandal Kingdom in 534. Byzantine rule lasted for 150 years. The Berbers contested the extent of Byzantine control.
