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 1 March 317, Constantine the Great and co-emperor Licinius elevated their sons Crispus, Constantine II (still an baby) and Licinius II to Caesars. After this arrangement Constantine ruled the dioceses Pannonia and Macedonia, and established his residence at Sirmium, from where he prepared a campaign against the Goths and Sarmatians.
