Query: When did Galerius revoke the anti-Christian policies?
Context: Others complied. Some local communities were not only pre-dominantly Christian, but powerful and influential; and some provincial authorities were lenient, notably the Caesar in Gaul, Constantius Chlorus, the father of Constantine I. Diocletian's successor Galerius maintained anti-Christian policy until his deathbed revocation in 311, when he asked Christians to pray for him. "This meant an ofﬁcial recognition of their importance in the religious world of the Roman empire, although one of the tetrarchs, Maximinus Daia, still oppressed Christians in his part of the empire up to 313."
