Why was Rome's divided rule bad?

Answer 1

Rome's divided rule, particularly during the Tetrarchy established by Diocletian, led to inefficiencies, communication breakdowns, and weakened central authority. The separation of the empire into Eastern and Western regions created rival power centers, which often competed against each other rather than collaborating for the empire's stability. This fragmentation contributed to internal strife and made it easier for external threats to exploit the divisions, ultimately hastening the decline of the Western Roman Empire.
