a. Christianity was the new state religion of the Roman Empire
Explanation:
The Edict of Milan brought freedom to Christians to profess their religion 1,706 years ago. This legal act proclaimed religious equality throughout the Roman Empire and stopped the persecution of Christians, which lasted for almost three full centuries.
The edict was signed by Emperors Constantine the Great and Licinius in present-day Milan, in February 313, but on 13 June the proclamation reached the east. This is where she was born and, therefore, came into force.
The Edict of Milan gave Christians the right to build their own churches, and the estates that had been confiscated during religious persecution had to be returned to the voodoo.
