Several key factors contributed to the fall of the Roman Empire, including political instability, economic decay, and military defeats. Political instability arose from internal conflicts between emperors, usurpers, and divided loyalties among the ruling class. Economic decay became apparent with the devaluation of Roman currency, high inflation, and heavy taxation. The constant invasions and attacks from barbarian tribes, such as the Visigoths and Vandals, weakened the Roman military and eventually led to the empire's fragility, exposing its weaknesses and ultimately causing the fall of the Roman Empire.
