Answer:
Visigoths sacked Rome after Emperor Constantine moved the Roman capital to Constantinople.
Explanation:
From the third century the Roman Empire began to face a serious crisis, which threatened the stability of the Roman territory. Barbarian invasions were a constant threat, especially from the peoples of northern Europe, such as the Visigoths and the Vandals, among others. They were responsible for conquering various portions of Roman territory.
The Vandals seized northern Africa, the Visigoths conquered the Iberian Peninsula, the Franks seized a portion of Gaul, and the Anglo-Saxons conquered Brittany, causing a severe weakening in the Roman Empire and shrinking its territory. These peoples threatened the empire not only by seizing their lands, but also by spreading their cultures in an empire that was intended to be homogeneous.
Thus, during the barbarian invasions Rome was sacked several times by different peoples. The first sack of Rome in this period was effected by the Visigoths in 410 AD This was after Emperor Constantine transferred the Roman capital to Constantinople.
