Some extra relevant information:
The kingdom of the Vandals and Alans was conquered by the Byzantine Empire led by the general Belisarius. This conquest took place in the year 533 during the Byzantine reconquest of the Western Roman Empire. The kingdom of the Vandals and Alans, which was established in the early 5th century, was situated in North Africa and had its capital in the city of Carthage.
The Vandals, originally a Germanic tribe, had migrated southward from their homeland and had eventually established a powerful kingdom in North Africa. The Alans, an Iranian nomadic group, had settled in the region and formed an alliance with the Vandals. Under the rule of King Gaiseric, the Vandals and Alans built a formidable naval fleet and became a force to be reckoned with in the Mediterranean.
However, their reign of power came to an end when the Byzantine Emperor Justinian I decided to retake the lost territories of the Western Roman Empire. The emperor appointed Belisarius, a skilled military commander, to lead the expedition against the Vandals and Alans.
Belisarius and his Byzantine forces launched a successful campaign that saw them retake several key cities in North Africa, including Hippo Regius and eventually Carthage. The conquest of Carthage marked the end of Vandal and Alan rule in the region. Many Vandals and Alans were either killed or captured, while others fled or were assimilated into the local population.
The Byzantine Empire reestablished its control over North Africa, which became known as the Exarchate of Africa. This Byzantine province would remain under the empire’s control until the rise of the Arab Muslim conquests in the 7th century.
The conquest of the kingdom of the Vandals and Alans by Belisarius was a significant event in the history of the Mediterranean region. It marked the restoration of the Roman presence in North Africa and contributed to the Byzantine Empire’s efforts to reclaim its former territories in the Western Roman Empire.
