In what ways are Constantine and Justinian similar?

Constantine and Justinian were both pivotal Byzantine emperors who significantly shaped the Roman Empire's legacy. They each played crucial roles in the spread of Christianity; Constantine issued the Edict of Milan, which legalized Christianity, while Justinian aimed to unify the empire under the Christian faith and commissioned the Hagia Sophia. Both rulers also implemented extensive legal reforms, with Constantine establishing a new capital in Constantinople and Justinian codifying Roman law through the Corpus Juris Civilis. Their reigns marked a transition from ancient Rome to the medieval Byzantine Empire, influencing governance and culture for centuries.
