Which leader first illustrated the fact that Rome's strength was decreasing?

Answer 1

The leader who first illustrated the decline of Rome's strength was Emperor Diocletian. His reign marked significant reforms aimed at stabilizing the empire, including the division of Rome into the Eastern and Western Roman Empires. Despite his efforts, the need for such drastic measures highlighted the empire's growing challenges and vulnerabilities, signaling a clear decline in its overall strength and cohesion. This period set the stage for further fragmentation and eventual fall of the Western Roman Empire.
