Constantine changed the conditions under which Christianity lived. Before him, the church could be persecuted; after the Edict of Milan in 313, it could own property, build openly, receive imperial favour, and gather bishops under imperial summons. He convened the Council of Nicaea in 325, founded Constantinople, and tied Christian history to Roman power in a new way. He did not make Christianity the state religion, and his own baptism came only at the end of his life, but every later Christian argument about empire, patronage, and political power runs through him.
