Regarding Emperor Diocletian's decision to split the Roman Empire into two sections:
Positive effect: One positive aspect of this decision was that it helped in the more efficient governance of the empire. By dividing the empire into two parts, the Eastern and Western Roman Empires, Diocletian was able to delegate power more effectively, enabling better administration of the vast territory and resources under Roman control.
Negative effect: On the other hand, a negative effect of this division was that it weakened the overall unity of the Roman Empire. The split led to differences in culture, administration, and priorities between the Eastern and Western Empires, ultimately contributing to the empire's decline and vulnerability to external threats.
In conclusion, while the division of the Roman Empire under Emperor Diocletian had its benefits in terms of governance, it also had downsides in terms of unity and cohesion.
