Constantine changed their name to?

Constantius had become severely sick over the course of his reign, and died on 25 July 306 in Eboracum. Before dying, he declared his support for raising Constantine to the rank of full augustus. The Alamannic king Chrocus, a barbarian taken into service under Constantius, then proclaimed Constantine as augustus.

Explanation:

julius caesar turned the roman republic into the roman empire by coming in and taking the "dictator" role during the time of a civil war (elites vs lower classes) winning battles and reputation, then declaring him dictator for life

hope this : )
