After eliminating Licinius, Constantine openly dynasticized the purple through Crispus (while he lived) and the sons of Fausta, abandoning the tetrarchic claim that emperors were made by adoption and Jovian/Herculian college.
Context
There was no democracy to erode. The analogical path is against a designed colleague-system that had, however bloodily, tried to de-familialize succession.
Constantine the Great’s documented role is bounded by other offices and collaborators named in the sources below.
Diocletian’s tetrarchy tried non-filial succession. Constantine made sons Caesars. Analogical: succession as family property rather than adopted colleagues.
Why it matters
Dynasty is not York 306.
