The fall of the Roman Empire is attributed to a combination of factors. First, the constant influx of barbarian invasions weakened the empire's military and infrastructure. Second, the empire's vastness made it increasingly difficult to manage, leading to rampant corruption, economic decline, and over-reliance on slave labor. Third, a series of weak, ineffective emperors was unable to address these mounting problems, resulting in political instability. Lastly, internal strife and religious disputes, particularly the rise of Christianity, contributed to the empire's fragmentation.
