Constantine II, whose full name was Flavius Claudius Constantinus, was the son of Constantine I and Fausta.[] Primary sources for the life and reign of Constantine II are scarce.[] He was probably born in Arles in the summer of 316 A.D. and, like his brothers, raised as a Christian. He was made a Caesar on 1 March 317 and was involved in military expeditions at an early age.[] For instance, in 323, he seems to have taken part in Constantine I’s campaigns against the Sarmatians.[] In 326, he was nominally put in command of Gaul at the age of 10 soon after the death of his half-brother Crispus.[] Constantine II’s generals apparently won a victory over the Alamanni, since the title Alamannicus appears on his inscriptions from the year 330.[] In 332 he was Constantine I’s field commander during the latter’s campaign against the Goths.[] Before 335 he was married, but his wife’s name is not known. In the years before his father’s death in 337, he held court in Gaul.[]
Following the death of their father on 22 May 337, and the subsequent murder of other relatives and heirs,[] Constantine II and his two brothers met in the first part of September 337 in Pannonia where they were acclaimed Augusti by the army to apportion the empire among themselves .[] Constantine’s new realm included Britain, Gaul, and Spain. Upon his accession, he freed the fiery Trinitarian Bishop Athanasius from his exile and allowed him to return to Alexandria. [] Whether Constantine II was motivated by sincere Trinitarian belief (popular in his realm) or if he wanted to cause problems from his brother Constantius II is unclear. In 340 Constantine II, in an attempt to seize some of his brother Constans’ realm, died in a battle fought near Aquileia.[]

[]For Constantine II’s name, see: ILS, 712-13, 721-2, 724; AE 1960, # 06; he is called Flavius Constantinus on one inscription: ILS 714. Constantine II’s early life is discussed by Otto Seeck, RE 4, s.v. “Constantinus (3),” col. 1026. 21f. For a listing of the sources that treat the parentage of Constantine II, see T. D. Barnes, The New Empire of Diocletian and Constantine (Cambridge, MA., 1981), 44. The authors of PLRE wrongly claim that Constantine II was a bastard of Constantine I (A. H. M. Jones, J. R. Martindale, and J. Morris, The Prosopography of the Later Roman Empire [Cambridge, 1971], s. v. “Fl. Claudius Constantinus 3,” 1. 223); this contention is based upon an argument from silence.
[]The surviving books of Ammianus Marcellinus, which present our best political source for the fourth century, begin their coverage with the Fall of 353. For sources for Constantine II, see the short references in Origo Constantini Imperatoris (=Anonymus Valesianus), Aurelius Victor, Eusebius, Eutropius, Zosimus, Orosius and Zonaras.
