Flavius Julius Crispus (died 326), also known as Flavius Claudius Crispus and Flavius Valerius Crispus, was a Caesar of the Roman Empire. He was the first-born son of Constantine I and Minervina.
By 313, there were two remaining Augusti in control of the Roman Empire—Constantine in the west and his brother-in-law Licinius in the east. On 1 March 317, the two co-reigning Augusti jointly proclaimed three new Caesars: Crispus, alongside his younger half-brother Constantine II, and his first cousin Licinius Iunior. Constantine II was the older son of Fausta but was probably about a month old at the time of his proclamation. Thus only Crispus assumed actual duties. Constantine apparently believed in the abilities of his son and appointed Crispus as Commander of Gaul. The new Caesar soon held residence in Augusta Treverorum (modern Trier), regional capital of Germania. (Wikipedia).
