Both Diocletian and Constantine were the Emperors of Rome who ruled Rome effectively. However, to rule more accurately both the emperors made some political and military reforms. These reforms included enlarging the army (to defend the empire from foreign invasions) and expanding the civil service etc. At the same time, the cost of maintaining an extensive army and people in the civil services hit the economy of the empire. Due to this, inflation arose throughout the empire which forced people to stay in their jobs.
