Domesticus (Roman Empire)

  (Redirected from Comes domesticorum)
The insignia of office of the two comites domesticorum of the Eastern Empire, according to the Notitia Dignitatum: the shields of the domestici and the codicils of office

The origins of the word domesticus can be traced to the late 3rd century of the Late Roman army. It stems from the term “Protectores Domestici”, a guard unit serving as the staff to the Roman Emperor.[1] It is said that they originated from being “comes”, which were companions, or counts in various offices and the emperor, in this case a guard unit.[1] They often held high ranks in various fields, whether it was the servants of a noble house on the civilian side, or a high ranking military position. After serving under the emperor for a certain duration, the Domestici would be able to become leaders themselves and potentially command their own regiment of legionnaires in the military. Relatively, the most important offices were the “Comes Domesticorum” also known as, “Commander of the Protectores Domestici,” and “Comes rei Militaris” or General.[1]



The domestici rose to prominence during the Crisis of the 3rd Century,[2] the crumbling and near collapse of the Roman Empire between 235 and 284 as Ancient Rome experienced a myriad of societal catastrophes that impeded on the structure of Ancient Rome’s civilization until Diocletian’s rule. He eventually came into power, ending the continual strife and unstable leadership Ancient Rome faced during “The Crisis of the 3rd Century”. It is logical that after events such as this, the title of “Domesticus” found its way into several aspects of Ancient Rome to advocate for better control over the empire. Implementing defined leadership in the military as officers; individual households and lands to overlook common civilians and servants; protection for the palace and the emperor himself; all to prevent further crisis’ in the future and transitioning into later periods of the Roman Empire.

Late Roman EmpireEdit

The roles of the domestici in the Roman Empire evolved during the late Empire.  From 330 AD to 474 AD they were given a variety of functions depending on whatever they were assigned to.  Many held positions as Generals and even elevated to become emperors if they gained enough notability.  Constantius Chlorus was a Domesticus that after many successful military campaigns became one of the joint Emperors of the Roman empire with Maximian.  Many of the notable Domestici of the Roman Empire existed around the time period which the Roman Empire was splitting into its eastern and western halves.  Many of Diocletian successors mirrored his successes because they to after many military successes gained a lot of notability and took the throne as emperor from the sitting emperor but many of them didn't have long reigns  because how unstable the western Roman Empire was.  These emperors were the ones that did realize because of their military experiences that it was not possible to sustain the size of the late Roman Empire leading to them continuing Diocletian’s idea to have it separated into the eastern and western halves.  This cycle of instability and military rule in the western Roman Empire continued until its fall in 476, and Zeno the last emperor of the eastern Roman Empire and the First Emperor of the Byzantine Empire where he ruled from August in 476 until his death in April 491.[1]

Byzantine EmpireEdit

As the Byzantine Empire was gaining strength economy, new patterns in governing from how things were in the late Roman Empire, and a growing bureaucracy in the early 500’s under the rule of the Byzantine Emperor Anastasius 1 the successor to Zeno the title of Domesticus was evolving and often being used as synonyms of Vicarius and Locoservator.  These titles basically translate to ‘vice’ which meant they basically reported to any superior this title wasn’t given to people in charge by the year 504 in the Byzantine Empire.[3] The translation of Domesticus, Vicarious, and Locoservator respectively mean belonging to a house, Vice meaning deputy or substitute for a superior, and subordinate to the count or duke.[3]
