Answer: Military, economic, political.
Step-by-step explanation:
The factors that influenced the weakening of the Roman Empire are still a topic of debate among historians.According to some historians, the cause of the empire's decline was the fact that the Romans increasingly relied on mercenary troops in time. These greedy barbarians will turn against Rome in time.
The spread of Christianity is considered by some to be a factor that led to the weakening of the empire. Namely, according to Christian dogmas, human rewards are expected after death, so that people have become less interested in the earthly, and indulge in what was promised to them after death. In this context, we can say that one of the factors is the abandonment of traditional values by the Romans.
According to some historians, the lack of a quality financial system has caused a weakening. Specifically, Rome relied on the looting of new territories. The Roman economy was based on robbery. Apart from the above, the specific income was in a way that taxed the farmers with high levies. This kind of economic policy required reform, but it did not happen.
The division of the Roman Empire into east and west is a factor that is also taken, as a reason for celebrating the empire.Weak investment in education and culture can be seen as a factor in the weakening of the empire; for the most part, the funds have been exposed to the military.
The occurrence of epidemics is also taken as a factor that has led to a weakening. Namely, epidemics that repeatedly decimated the population led to depopulation. The administration was massive, and after the plagues, there was no one to fill the government coffers. These events have reduced the funding for the military.
The incursions of barbarian tribes into the frontiers of the empire were increasingly frequent over time, which was definitely reflected in the weakening of the empire. Barbarian invasions caused long-term damage to the realm.
