Constantine I

Constantine I was the son of Flavius Valerius Constantius—an army officer who later became the Roman emperor known as Constantius I Chlorus—and his wife or concubine, Helena.12
In 289 CE, Constantius separated from Helena to marry Theodora, the stepdaughter of the emperor Maximian, for political reasons. Following this separation, Constantine was raised in the Eastern Empire at the court of the emperor Diocletian.12
