What did consantine do to stabliZe the empire?

Answer 1

Constantine the Great stabilised the Roman Empire by winning two civil wars (one against Maxentius, a usurper emperor in Italy, and one against his co-emperor, Licinius) and becoming sole emperor. The emperor Diocletian had set up the tetrarchy (rule by four) whereby the Roman Empire was ruled by two senior emperors (Augusti, plural of Augustus) and two junior emperors (Caesars), with each one of the four emperors in charge of a part of the empire. When Diocletian and the other senior emperor (Maximian) abdicated there were power struggles in the empire. When Constantius Chlorus (Constantine's father) who had been a Caesar and then became an Augustus, died a year later Constantine wanted the become the Augustus of the western part of the Roman Empire. However, he was appointed as only a Caesar. Meanwhile, Maxentius usurped the imperial title in Italy and made himself emperor of Italy and Africa. Constantine, in his bid to become an Augustus, organised political support in the area of the empire he controlled (Britain and Gaul) and then fought against Maxentius and defeated him. With this he became the emperor of the western part of the empire, while Licinius was the emperor of the eastern part. Constantine and Licinius then fought each other. Constantine won this civil war, too, and became the sole emperor of the whole empire. Having a sole emperor brought the civil wars to an end and stabilised the empire.
