The younger Constantine was appointed to hold his court in Gaul; and his brother Constantius exchanged that department, the ancient patrimony of their father, for the more opulent, but less martial, countries of the East.
Italy, the Western Illyricum, and Africa, were accustomed to revere Constans, the third of his sons, as the representative of the great Constantine.

He fixed Dalmatius on the Gothic frontier, to which he annexed the government of Thrace, Macedonia, and Greece.

The city of Caesarea was chosen for the residence of Hannibalianus; and the provinces of Pontus, Cappadocia, and the Lesser Armenia, were destined to form the extent of his new kingdom.

For each of these princes a suitable establishment was provided.

A just proportion of guards, of legions, and of auxiliaries, was allotted for their respective dignity and defence.
The ministers and generals, who were placed about their persons, were such as Constantine could trust to assist, and even to control, these youthful sovereigns in the exercise of their delegated power.
