Question

what effect did the Barbarian invasions have on the Byzantine Empire​

Answer 1

For the fall of Rome, it was the Huns invading from the east that caused the domino effect, they invaded (pushed into) the Goths, who then invaded (pushed into) the Roman Empire. The fall of the Western Roman Empire is a great lesson in cause and effect. A cause leads to an effect.

Answer 2

Answer:

The most straightforward theory for Western Rome's collapse pins the fall on a string of military losses sustained against outside forces. Rome had tangled with Germanic tribes for centuries, but by the 300s “barbarian” groups like the Goths had encroached beyond the Empire's borders.
