Which emperor ended the persecution of Christians?

"Galerius ended the persecution in the East in 311, but it was resumed in Egypt, Palestine, and Asia Minor by his successor, Maximinus. Constantine and Licinius, Severus's successor, signed the "Edict of Milan" in 313, which offered a more comprehensive acceptance of Christianity than Galerius's edict had provided.
