Dictionary of Christian Biography and Literature to the End of the Sixth Century/Constantinus II., eldest son of Constantine the Great
Constantinus II., the eldest son of Constantine the Great by Fausta, born A.D. 312, was made Caesar in 316 together with Crispus, and his quinquennalia were celebrated by the panegyric of Nazarius in 321. At the death of his father, the empire being redivided, Constantine as the eldest son seems to have claimed Constantinople, but this was overruled, and he was placed over the West. Constantine thus came into contact with St. Athanasius in his exile at Trèves, and at once took him under his protection. [ Athanasius.] In 340 Constantine invaded the dominions of Constans and penetrated into Lombardy, where he was killed in a small engagement. His dominions then went to Constans, who thus ruled the entire West. Of his character we know little or nothing. He appears to have been a staunch Catholic, but his attack upon the dominions of his brother Constans does not put his character in a favourable light. His short reign makes him very unimportant.
