Catholics
1
The roman Catholic Church was established by Constantine, the Roman Emperor of the eastern Roman Empire, at a time when the Christians were becoming a threat to the authorities and there was a need to control them and "persecute" them. Grouping a number of compromised Christians the religion was built out of a mixture of Christian teachings and pagan religion mysticism. Once established as the official Church of the Roman Empire, all who did not adhere to it were considered heretics and enemies of the Empire, were persecuted and even put to death.
