Early Christian persecution and pagan persecution by Christians a historical analysis Part 1

Why did the early Christian persecution happen? How extensive was it and could one argue that it's over-exaggerated?
In this two-part series we will cover the history of the early Christian persecution in Rome. This will include why the roman pagans decided to persecute Christians, how extensive the persecution was as well as the often less talked about persecution of pagans by Christian emperors in late antiquity.
This video will cover the early Christian persecution with part two covering the later pagan persecution by Christians.
