ミラノ勅令
In 311, Emperor Galerius, on his deathbed, declared a religious indulgence to Christians throughout the Roman Empire, focusing on the ending of anti-Christian persecution. Constantine I and Licinius, the two "Augusti", by the Edict of Milan of 313, enacted a law allowing religious freedom to everyone within the Roman Empire. Furthermore, the Edict of Milan cited that Christians may openly practice their religion unmolested and unrestricted, and provided that properties taken from Christians be returned to them unconditionally. Although the Edict of Milan allowed religious freedom throughout the Empire, it did not abolish nor disestablish the Roman state cult (Roman polytheistic paganism). The Edict of Milan was written in such a way as to implore the blessings of the deity.
