Christian Persecution Under Emperor Galerius (AD 305-311)
Galerius ruled as emperor for six years, from 305 to 311. Following the brutal policies of Diocletian, Galerius continued to persecute Christians throughout Asia Minor (modern Turkey) until he issued the Edict of Toleration on April 30, 311 giving Christianity a legal status in the Roman empire.
The Edict of Toleration was the first imperial edict legalizing Christianity and the proclamation was
displayed on the streets of Nicomedia (modern Izmit).
