In this new partition of the Empire the Cæsarship of the West, including Gaul, Britain, and Spain, fell to Constantine, the eldest of the three princes. To the second, Constantius, were assigned the rich provinces of the East, including the seaboard provinces of Asia Minor, together with Syria and Egypt. Constans, the youngest, received as his share Italy, Illyria, and Africa. But there was still a goodly heritage left over, sufficient to make a handsome dowry for a favourite daughter. This was Constantina, eldest of the three daughters of Constantine and Fausta, and she had been married to her half-cousin, Annibalianus, whose father had been the second son of Constantius Chlorus and Theodora. To support worthily the dignity of his new position as son-in-law of Constantine, the new title of _Nobilissimus_ was created in his honour, and a kingdom was made for him out of the provinces of Pontus, Cappadocia, and Lesser Armenia. Gibbon expresses surprise that Annibalianus, “of the whole series of Roman Princes in any age of the Empire,” should have been the only one to bear the name of _Rex_, and says that he can scarcely admit its accuracy even on the joint authority of Imperial medals and contemporary writers. The explanation is surely to be found in the fact that Pontus, Cappadocia, and Lesser Armenia had for centuries been accustomed to be ruled by a king and that, in creating a new kingdom, Constantine simply retained the title which would be most familiar to the subjects over whom Annibalianus was to rule. Annibalianus was himself a second son: his elder brother, Dalmatius, was raised to the full title of Cæsar and given command over the important provinces of Thrace and Macedonia, with Greece thrown in as a make-weight. The position was a very important one, for it fell to the Cæsar of Thrace to guard the frontier chiefly threatened by the Goths, and we may suppose, therefore, with some probability that Dalmatius—who had been consul in 333—had given proof of military talent.
