Background: Mommsen's Conception
Origin of the Terms
The concepts of the Principate and the Dominate as distinct periodizations of the Roman Imperial era were introduced by the historian Theodor Mommsen. He proposed this division based on his interpretation of changes in the Roman Empire's constitutional and political structure during late antiquity. While influential, these terms are now largely considered by contemporary scholars to be unsuitable for precise historical periodization.
Characteristics of the Dominate
Mommsen characterized the Dominate, particularly the era of Diocletian and Constantine, as a period of decline and a departure from the earlier Principate. Key features he identified include:
- Imperial Model: An adoption of the oriental ruler as a model, moving away from the earlier magisterial nature of the Emperor's position.
- Division of Empire: A shift towards the division of the Empire into distinct Greek and Latin halves, contrasting with the unity of the Principate.
- Administrative Reform: A complete overhaul of the administration, with Italy losing its privileged status and a new capital city emerging.
- Military Transformation: The military evolved into a more effective and mobile force, distinct from the frontier-focused troops of the Principate. Foreigners, notably Germans, began to join the army in significant numbers.
- Financial Administration: The development of an effective finance administration, including Constantine's reintroduction of the gold Solidus.
- Religious Shift: The emergence of a new religion that differed from that of the Principate, though Mommsen notes it was not exactly Christian in its early form.
Imperial Titles and Adulation
Mommsen observed a significant change in imperial titles and the associated ceremonies during the Dominate:
- Emphasis on Augustus: Increased prominence of the title Augustus, often combined with Pius felix, perpetuus Augustus, and semper Augustus, imbuing the position with greater divine or perpetual authority.
- Emergence of 'Dominus': The title dominus (lord), initially associated with slave owners, became a common form of address for the Emperor, and eventually for deities. This title began appearing on coins, notably combined with deus (god) under Aurelian, signifying a profound shift in imperial ideology.
- Ceremony of Adoration: Diocletian introduced the ceremony of genuflection, a practice closer to oriental court customs, which contrasted sharply with the more accessible interactions of the Principate and caused friction, particularly with Christian sensibilities regarding the concept of a living god on earth.
Imperial Structure and Ideology
Division and Centralization
Mommsen's analysis suggests that the Dominate saw a move towards the division of the vast Roman Empire, creating distinct Greek-speaking Eastern and Latin-speaking Western spheres. This contrasted with the perceived unity under the Principate. Concurrently, there was a significant reform and centralization of the administration, moving away from the more decentralized structures of the earlier period.
Military Evolution
The military underwent substantial changes. While the Principate relied heavily on frontier troops, the Dominate era saw the development of a more mobile and effective field army. This period also witnessed an increased integration of foreign elements, particularly Germanic peoples, into the Roman military structure, reflecting broader demographic and political shifts.
Financial and Religious Shifts
Economically, the Dominate period saw the establishment of a more robust financial administration. Constantine's reintroduction of a stable gold currency, the Solidus, was a critical development in stabilizing the imperial economy. Religiously, while Mommsen notes a new religion emerged, distinct from the paganism of the Principate, its relationship with Christianity was complex, leading to ideological conflicts concerning the divine nature of the Emperor.

Historiographical Debate
Bleicken's Challenge
The historian Jochen Bleicken, in 1978, critically challenged Mommsen's division of the Roman Imperial era into Principate and Dominate. Bleicken argued that this division was not based on fundamental constitutional changes but was rather an interpretive framework imposed by Mommsen.
Bleicken contended that the terms were unsuitable for accurate periodization and suggested they might have been influenced by a desire to portray the later Roman Empire as "un-Roman" and distinct from the classical Greco-Roman tradition, possibly reflecting 18th and 19th-century political sentiments concerning absolutism versus liberty.
Continuity in Practice
Further analysis by Markรฉta Melounovรก in 2012 examined judicial trials concerning religious and political crimes. Her findings indicated that the actual legal practices and punishments did not significantly differ between the periods Mommsen designated as the Principate and the Dominate, suggesting a greater continuity than Mommsen's periodization implied.
Modern Perspective
Contemporary academic consensus, as reflected in resources like the Oxford Classical Dictionary, regards the term Dominate as largely obsolete. While Mommsen's conceptualization was historically significant, modern scholarship tends to favor more nuanced approaches to understanding the evolution of the Roman Empire, recognizing continuities and complexities that transcend simple binary periodizations.
