After the chaos described in
Topic 18, Rome needed rulers who could rebuild trust.
Constantine rose through the ranks of the tetrarchy system created by Diocletian. By the early fourth century he fought civil wars to become sole ruler of the western empire, then the whole Roman world. Constantine is remembered not only as a general and builder, but as the emperor who changed Rome's relationship with
Christianity. His reign linked church and state in ways that shaped Europe and the Mediterranean for centuries. The
Arch of Constantine still stands near the Colosseum as a stone monument to his victory and fame.
👑 RULE
Constantine ruled as emperor from 306 CE until his death in 337 CE. He reunited the empire and launched reforms in law, coinage, and religion.
