Flavius Julius Crispus was the son of Constantine I by his first wife. A brilliant soldier, Crispus was well loved by all until 326 A.D., when Constantine had him executed. It is said that Fausta, Crispus stepmother, anxious to secure the succession for her own sons falsely accused Crispus of raping her. Constantine, learning of Fausta's treachery, had her executed too.
On 3 July 324, at Adrianople, Constantine defeated Licinius forcing him to retreat to Byzantium. Crispus destroyed Licinius' fleet at the Battle of Hellespont in the Dardanelles, allowing his father to cross over the Bosporus and besiege Licinius. On 18 September, Constantine I decisively defeated Licinius at the Battle of Chrysopolis and became sole emperor.
