I want to know the answer to the following question:
When did Galerius revoke the anti-Christian policies?
All the background I'm provided with is that "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. "". Is that enough to answer the question?
Answer: yes
