Who Constantine II was

Constantine's eldest surviving son, ruler of Gaul, Spain, and Britain from Trier — the brother in whose territory Athanasius passed his first exile, and who sent the bishop home to Alexandria with a letter of honour on their father's death. Claiming a guardian's precedence over young Constans, he invaded Italy in 340 and was killed in an ambush at Aquileia: the first fratricide of the Christian dynasty.

Also listed in non-christian witnesses and roman emperors.
