The Vandals were a group of Germanic peoples who were first mentioned by a small number of Roman writers in the first and second centuries. The Vandal name reappeared in Roman accounts in the late second century during the tumultuous Marcomannic Wars of the Romans against many of the Germanic peoples north of the Danube, when Hasdingi-led Vandals took the side of the Romans, in exchange for territory in or near Dacia. It was also under Hasdingi leadership that large numbers of Vandals migrated and formed a powerful Vandal Kingdom which ruled Roman North Africa for several generations until it was conquered by the Eastern Roman Empire in 534.
