Final answer:
Having a strong leader was important for the Byzantine Empire due to external threats, internal challenges, and the need for diplomacy.
Step-by-step explanation:
A strong leader was especially important for the Byzantine Empire due to the various external threats it faced and the need for effective diplomacy. The empire was surrounded by hostile states and groups, and it slowly lost territory over many centuries. Having a strong leader who could navigate the economic and military situation, form alliances, and protect the empire's borders was crucial for its survival and longevity.
In addition, the internal challenges faced by the Byzantine Empire, such as powerful elites seeking to exploit weaknesses in the rule, required a strong leader to maintain control and curb the power of these elites. The Byzantine rulers also had to deal with inconstant allies and ferocious enemies, which further highlighted the need for a strong and capable leader.
