Gelasius I is elected pope. The third and last pope from Africa, his main concerns will be orthodoxy and papal primacy. When it comes to orthodoxy, he will reject the Monophysite heresy that is taking hold in the eastern Church, even though that will deepen the rift between east and west. He will also suppress various pagan celebrations and practices in Rome, like for example Lupercalia (which will nevertheless reemerge as St. Valentine's Day).
Ironically, the efforts of Pope Gelasius I to enforce Christian orthodoxy are aided by his alliance with the Ostrogoth leader Theodoric, successor to Odoacer. Theodoric was an Arian heretic, but also tolerant of others and thus accorded Gelasius a lot of latitude in administering the church and regulating doctrine.
