The correct answer is C) dividing the empire into eastern and western regions.
One way Diocletian brought short-term order to Rome involved dividing the empire into eastern and western regions.
The Roman Empire constantly grew in size, extending its dominions to faraway places. In times of Diocletian (became Roman Emperor in 284 CE and ruled until 305 CE) he was conscious that governing the vast empire had become a difficult task. So aware of this situation, he divided the empire into two regions. He named a Caesar to rule the west portion of the empire, his son-in-law Maximilian, who changed his name to Marcus Aurelius Valerius. Meanwhile, Diocletian still rued the east part of the empire.
