Edict of Milan

The Edict of Milan (Edictum Mediolanense; Διάταγμα τῶν Μεδιολάνων, Diatagma tōn Mediolanōn) was the February 313 AD agreement to treat Christians benevolently within the Roman Empire. Western Roman Emperor Constantine I and Emperor Licinius, who controlled the Balkans, met in Mediolanum (modern-day Milan) and, among other things, agreed to change policies towards Christians following the edict of toleration issued by Emperor Galerius two years earlier in Serdica.
