b) A crumbling government system.
The decline of the empire, referring to the Byzantine Empire, was influenced by various factors, but a significant contributor was the gradual deterioration of its government system.
The Byzantine Empire had a complex bureaucracy and administrative structure that had been successful in earlier centuries. However, over time, this system became inefficient, corrupt, and increasingly difficult to maintain.
Issues such as bureaucratic red tape, nepotism, and the inability to effectively govern and administer the vast territories of the empire weakened its central authority. The empire faced challenges in collecting taxes, maintaining law and order, and responding to external threats.
The crumbling government system made it difficult for the Byzantine Empire to effectively manage its resources, defend its borders, and maintain stability. This created opportunities for external forces to exploit the empire's weaknesses.
While other factors such as Arab Muslim conquests, the impact of the plague, and the death of Justinian I played a role in the decline of the empire, the crumbling government system was a key factor that contributed to its gradual downfall.
