Constantine the Great legalized Christianity, presided over the Council of Nicaea, and is revered as a saint by the Eastern Orthodox Church. He also executed his eldest son Crispus and had his second wife Fausta killed in an overheated bath — crimes the Church has spent seventeen centuries trying to explain away or ignore. The emperor who gave Christianity its political power was also a murderer whose family killings remain one of antiquity’s darkest unsolved mysteries.

This episode traces Constantine from his rise through the Roman military through the Battle of the Milvian Bridge, the Edict of Milan, the Council of Nicaea, and the family murders that stain the legacy of Christianity’s most important imperial patron.
