Constantine was a Roman emperor who ruled from 306 to 337 CE and is best known for being the first Christian emperor of Rome. He played a crucial role in the spread of Christianity by issuing the Edict of Milan in 313 CE, which granted religious tolerance to Christians and allowed the faith to flourish within the Roman Empire. His establishment of Constantinople as a new imperial capital also marked a significant shift in the political and cultural landscape of the empire, especially as it became a center of Christian influence.
