Although the story of the Roman Emperor Constantine’s conversion to Christianity has often been told in a simple, straightforward way, recent research shows a more complex picture. Other than Eusebius’ Life of Constantine, there is little evidence demonstrating that Constantine knew much about his new religion. In fact, Constantine may have worshipped the cult of the “unconquered son” as evidence from coins and statues suggests. His conversion, which took place in a dream or during a vision he saw in battle, depending on which version you read, linked his victory at the Milvian Bridge in 312 AD to the Christian god or sun god Apollo. But whether this was a genuine religious conversion, or a clever political decision to keep Christian and pagans happy is hard to tell.
