Was Licinius related to Constantine the Great?
Both Licinius and Constantine held the title of Augustus in the Roman tetrarchy, and sought to become the sole emperor of the Roman empire. Although both were from the region of Dacia, it is unlikely that they were related. In order to boost his claim to the principate, Constantine claimed to be descended from Claudius II. For the same reason, Licinius claimed descent from Philip the Arab. Although both claims were spurious, they do show that the two claimants were not regarded as related.
