Final answer:
Political instability, military mistakes, economic and civic decay were the main causes of the fall of the Roman Empire.
Step-by-step explanation:
Political instability, military mistakes, economic and civic decay were the primary factors that led to the decline and fall of the Roman Empire. Political instability allowed for corrupt emperors to come to power, which weakened the governance and stability of the empire. Military mistakes, such as relying on mercenaries instead of Roman soldiers, and over-expansion, strained the military resources of the empire.
Economic and civic decay also played a significant role in the downfall. The Roman economy became increasingly dependent on slave labor and lacked innovation and investment. The high taxes imposed by the empire and the corrupt practices of the ruling elite further contributed to economic decline.
Additionally, the loss of civic virtue and the erosion of moral values weakened the social fabric of the empire. This led to a decline in citizen participation and a loss of loyalty towards the empire, exacerbating the existing problems.
