Constantine

Constantine, also known as Constantine the Great, was Roman Emperor from 306 to 337 AD. He is notable for being the first Roman emperor to convert to Christianity and for supporting its growth within the empire. Constantine enacted key reforms, including the Edict of Milan in 313, which granted religious tolerance to Christians. He also founded the city of Constantinople (modern Istanbul), making it a new imperial capital. His reign marked a turning point that helped Christianity become the dominant religion of the Roman Empire, influencing Western history and religious development for centuries.
