Final answer:
The Visigoths were a Germanic tribe who sacked Rome in 410 CE, marking a significant event in the decline of the Roman Empire.
Step-by-step explanation:
The Visigoths were a Germanic tribe who invaded and looted Rome in 410 CE.
The Visigoths were one of several Germanic groups that pushed into Roman territory after the fall of the Western Roman Empire. They settled in Gaul and then seized most of Spain from the Vandals, who had arrived before them.
The sack of Rome by the Visigoths in 410 was a significant event in the decline of the Roman Empire, as it marked the first time in nearly seven hundred years that the city of Rome had been breached by non-Romans.
