Answer:
B
Step-by-step explanation:
In 476 BC the Western Roman Empire fell. This is also the time where the Western and Eastern Empires united. The Western side had a weak government and was often invaded by barbarian tribes. Groups like the Goths had encroached beyond the Empire’s borders. This allowed for the union of the Western and Eastern Empires.
