Previous to this, he had purportedly only advocated banning Christians from such things as the military and ruling body in hopes that would appease the gods.Afterward, he switched to an escalating policy of persecution to try to get Christians to worship the Roman gods.This began simply via seizing Christian’s property, destroying their homes, burning all Christian texts, etc.
); the latter means “in the year of the lord,” often translated as “in the year of our lord.” (It was thought when the AD dating system was created that its year 1 was the year Jesus of Nazareth was born.) was the first of these to appear.
Prior to the 6th century AD, many Christians who didn’t use an Anno Mundi (in the year of the world) type system relied on Roman dating, either marking dates from the year legend had it that Romulus and Remus founded Rome (753 BC) or by relying on the date system established under the Roman emperor Diocletian (244-311), based on the accession of Diocletian.
However, most Christians weren’t too fond of Diocletian, since he brutally persecuted them in the latter part of his reign in the late third / early fourth century.
This was in part a response to advice Diocletian received at the oracle of Apollo at Didyma.
When that didn’t work, Christians began to be killed in various brutal ways including occasionally being torn apart by animals for the amusement of the masses (Damnatio ad bestias).
This method of convincing people to worship the Roman gods ended up being an amazing failure and the persecution appears to have only continued after AD 305 in the Eastern half of the empire under Galerius and Maximinus.
Finally, in April of AD 311, by imperial decree, the Great persecution was put to an end even in the East.
A few years later, Constantine the Great (reigning from AD 306 to 337) publicly declared himself a Christian and Christianity began to transition into the dominate religion in the Roman Empire.
In any event, Easter was/is the most important holy day of the Christian tradition, and it was decided at the First Council of Nicaea (AD 325) that it should occur each year on the Sunday following the first full moon after the spring equinox.
