The Vandal Kingdom (Regnum Vandalum) or Kingdom of the Vandals and Alans (Regnum Vandalorum et Alanorum) was a confederation of Vandals and Alans, which is one of the barbarian kingdoms established under Gaiseric, a Vandal warrior. It ruled in North Africa and the Mediterranean from 435 to 534 AD.
In 429 AD, the Vandals, estimated to number 80,000 people, had crossed by boat from Hispania to North Africa. They advanced eastward, conquering the coastal regions of what is now Tunisia, and Algeria. In 435, the Roman Empire, then ruling North Africa, allowed the Vandals to settle in the provinces of Numidia and Mauretania when it became clear that the Vandal army could not be defeated by Roman military forces. In 439 the Vandals renewed their advance eastward and captured Carthage, the most important city of North Africa. The fledgling kingdom then conquered the Roman-ruled islands of Mallorca, Sicily, Sardinia, and Corsica in the western Mediterranean. In the 460s, the Romans launched two unsuccessful military expeditions by sea in an attempt to overthrow the Vandals and reclaim North Africa. The conquest of North Africa by the Vandals was a blow to the beleaguered Western Roman Empire as North Africa was a major source of revenue and a supplier of grain (mostly wheat) to the city of Rome.
Although primarily remembered for the sack of Rome in 455 and their persecution of Nicene Christians in favor of Arian Christianity, the Vandals were also patrons of learning. Grand building projects continued, schools flourished, and North Africa fostered many of the most innovative writers and natural scientists of the late Latin-speaking Western Roman Empire.
The Vandal Kingdom ended in 534, when it was conquered by Belisarius in the Vandalic War and incorporated into the Eastern Roman Empire (or Byzantine Empire). The surviving Vandals either assimilated into the indigenous African population or were dispersed among the Byzantine territories.
