In 313, Constantine, the emperor of Rome, issued the Edict of Milan to mandate tolerance for all religions. It was a follow up of the Edict of Toleration by Galerius in 311. Constantine issued the Edict of Milan on February 313 AD with the purpose of treating Christians benevolently in the Roman Empire. It gave Christianity a legal status but it did not make Christianity the official religion of the Roman Empire. However, there are some arguments whether a formal Edict of Milan was given.
