Editing Dominate (section)

== Background ==
The historian [[Jochen Bleicken]] credits [[Theodor Mommsen]] with introducing the concepts of ''[[Principate]]'' and ''Dominate'' into the literature to periodise the Roman Imperial era.{{sfn|Bleicken|1978|p=6}}

Based on lecture notes of Sebastian and Paul Hensen in Mommsen's lectures (1882-6) and that were published posthumously as part of his ''[[The History of Rome (Mommsen)| History of Rome]]'', Mommsen explains the concept as follows:{{sfn|Mommsen|2005|p=371}} 
<blockquote>[MH.III, 1] The era of Diocletian bears the mark of decline, and does not attract our sympathy. The significance of this era, however, is all the greater because of this very decline and the paucity of intellectual resources at its disposal. The dominate of Diocletian and Constantine differs sharply from the principate's position,  the Republic. The oriental ruler provides the model for the domimate. Whereas the unity of the Empire prevailed under the principate, the division of the Empire prevailed under the dominate. The nationalities divided into a Greek and Latin half. Whereas the principate had been Latin-Greek, the dominate was Greek-Latin. There was a different capital city; Italy loses its privileged status, and there is a complete reform of the administration. The military machines turns into an effective and mobile one; the principate had only frontier troops. Foreigners now join the army, above all Germans. An effective finance administration also develops and Constantine reintroduces the universally current gold coin, the ''Solidus''. A new religion emerges which, although not exactly Christian, nevertheless still differs from that of the principate.</blockquote>

Mommsen continued the distinction in [MH.III, 8]:{{sfn|Mommsen|2005|p=375}}
<blockquote>There was increased emphasis on the title ''Augustus'', since the old tripartite title highlighted the magisterial nature of the Emperor's position. The title ''Pius felix'' made an early appearance and was already imbued with supernatural overtones. Later there was frequent use of the titles ''perpetuus Augustus'' and ''semper Augustus'' (forever Augustus). The word ''dominus'', which initially denoted slave-owners, became a new title for the Emperor, as well as for a god. Throughout the entire principate this title vied  with the legitimate one; even the earlier Emperors had difficulty fending off adulation of this kind. Gradually the dominate prevailed. Domitian was already a key figure in the process. In the third century this way of addressing the Emperor began to gain ground. The coins are an expression of official power: in the reign of Aurelian the title ''dominus'' first appeared on coins, combined with ''deus: domino et deo nato'' - born to be lord and god. We might supplement this with: ''servi et cives Romani'' - Roman citizens born to be slaves. From then onwards it appeared more frequently on coins, especially in the case of the other Emperors, but still the Emperor did not style himself as such until the era of Constantine. This marks another victory for the Greek element: among the Greeks deification of the living is as ancient as monarchy itself. The ceremony of adoration was a practical application of this; people shook hands with the earlier Emperors, or kissed them, like other distinguished persons. Diocletian introduced genuflection. This, too represented a move closer to the oriental idea. It aroused opposition in Rome. The idea of the Emperor as a deity could not be reconciled with Christianity: the idea of the god on earth was abandoned, the lord on earth remained.</blockquote>
