Reasons of the fall of roman empire?

one of the main reasons the roman empire fell is because of foreign invasions and another reason is because of the natural disasters they had to endure.

The Barbarian attacks on Rome partially stemmed from a mass migration causedby the Huns' invasion of Europe in the late fourth century. When these Eurasian warriors rampaged through northern Europe, they drove many Germanic tribes to the borders of the Roman Empire.
