Final answer:
The Roman Empire came to an end due to various factors, such as the inability of the military to defend against barbarian invasions and internal political problems.
Step-by-step explanation:
The Roman Empire came to an end due to a combination of factors. One of the main reasons was the inability of the Roman military to effectively defend against barbarian invasions. These invasions became more frequent and more organized, leading to the weakening and eventual collapse of the empire. Additionally, internal political problems such as corruption and infighting among the emperors contributed to the decline of the empire. The loss of tax revenues and the challenge of governing a large territory also played a role in the collapse.
