Although Roman Britain is often regarded as a single province this was true only for its first 169 years as part of the Empire. The status of the province remained unchanged until the legions had advanced north, and the entire province had been suitably pacified. It was when this point was reached it was decided that the administration of Britain could be safely divided. This was achieved in three stages: first the province it was divided into two provinces by Emperor Caracalla in 212 AD, then it was divided into four provinces by the Emperor Diocletian in 269 AD, and finally a fifth province was added by Emperor Valentinian in 369 AD. Britain did not in fact become a single entity again until it was unified by an English king almost 700 years later.¹

The Administration Centres of the Province of Britain

The Province of Britannia was the title of the first administration of the province.

From the invasion in 43 AD until 212 AD.

The first Provincial Capital was Camulodunum now Colchester.

Britain was an imperial province ² and the appointment of the governor or legatus Augusti³ was the choice of the Emperor and was a senator from the highest classes in Roman society.

There were 36 Provincial Governors of Britain from the date of invasion until the 207 AD division, interestingly the average term of office was just 4.5 years. One the longest terms served in office was that of Quintus Antistius Adventus⁴
from 169 to 180 AD, a total of 11 years.


Roman governors were given full control of all the military forces stationed in the province and could take any military action without prior consent of the emperor or the senate.

The governor was also the supreme judicial authority of the province and was the only person who could order the imposition of the death penalty.

Financial duties included the audit of the financial records of the cities within the province, and to set taxation rates and appoint tax collectors.

The term of office a governor served was strictly monitored, owing to the power of the position it was possible for a governor to contemplate an abuse of his position and become corrupt. To curb such abuses the term of office was normally limited to a minimum of 1 year and a maximum of 5 years. 'It is the part of a good shepherd to shear his flock, not to skin it' Roman proverb.

The early Provincial Governors devolved some of their administrational duties to the rulers of Rome’s client Kingdoms⁵ in Britain the Brigantes, the Iceni, the Catuvellauni the Atrebates and the Regnenses, the king of the Regnenses, Cogidumnus became a client king of Rome and was instrumental in the success of the landings in AD 43. After the invasion he Romanised his name to Tiberius Claudius Cogidumnus in honour of his patron Emperor Claudius. His reward for his services was the palace complex at Fishbourne. As the occupation progressed more tribes came under Roman rule. It was when the tribes had accepted Roman rule, they were incorporated into the regional government of the province.

Therefore from the earliest days of the invasion it was decided to base the administration of the new province upon the tribal kingdoms of Britain. Tribal capitals⁶ were set up around Britain to oversee the regional government of the area. A city council or citivas was established in each tribal capital by Rome and ruled the area with the aid of an elected council of around 100 members. The council members were at first chosen from the ranks of the local elite, later they were elected and wealthy and prominent citizens were included. The council members were awarded the civic position or rank of duovir or duovir quinquennalis. To lead the council two of its members were elected by to serve in the office of duumviri or magistrate. These men were held directly responsible to the provincial governor for the efficient administration of the region.

The region that was administered by the citivas was further divided into regional councils known as pagi. Each individual pagus⁷ was centred on a large settlement within their administrative area and these were responsible for all local administration, and the selection of local magistrates and other officials. It was here that regional elections were held for the local representatives to provincial council at the citivas.


This was the regional system that worked very well throughout the empire.⁸ All local government was responsible to the provincial government, this had also had a council which was known as the concilium provincae. The provincial council was held at the capital of the province all regions sent representatives to attend debates on provincial policy, this gathering was overseen by the governor and his officials. The governor was directly responsible to Rome for the security, profitability and the smooth running of the province.

The tribal capitals were established throughout the province one in each of the tribal religions these settlements became known as a civitas capital. Of the 19 recorded citivas or tribal capitals 17 of them had the tribal name incorporated into the name of the city. This dose not mean that there were just 19 tribes in Britain, there were in fact at least 44. It simply means that these were the pre-eminent tribes or client kingdoms that were selected by the Romans to participate in the regional government the province.


Despite the later reorganisations of the Province of Britannia in 212 AD, 269 AD and 369 AD, this administration system remained unchanged and was used until the abandonment of the province.

The division of the province of Britain in 212 AD, by Emperor Caracalla

It appears that this division of the province in to two and the subsequent divisions in in 269 AD and 369 AD, had little or no effect on the regional or local government. The system that was from the earliest days continued unaffected with only the promotion of Cirencester, Lincoln and York to the status of provincial capitals and the possible relocation of the conciliun provincae to those cities.

The Province is divided by Emperor Caracalla in 212 AD, into two provinces in accordance with political differences. It may have nothing to do with the division of the province, however the year 212 AD was also the year that the entire freeborn population of the empire,¹⁵ who were not slaves, were granted full Roman citizenship. This may indicate another aspect of the imperial policy or it may be coincidence, but the empire was changing. The south where the population was readily adopted Roman ways and were practically self governing. This reorganisation of the province created the following administrative areas -

The Province of Britannia Superior was the title of the second administration region of the Province.

From 212 AD, to 293 AD.

The Provincial Capital was Londinium - London.

The north where the population had not adopted Roman ways and were still unsettled this area was still a border zone and there still some activity between Hadrian’s wall and the Antonine Wall to the north. There was still a strong garrison force established at bases such as Eboracum - York and Lindum - Lincoln. This province was -

The Province of Britannia Inferior was the title of the second administration region of the Province.

From 212 AD, to 293 AD.

The Provincial Capital was Eboracum - York.¹⁶

Why the province was divided is unclear, it probably was a simple matter of making administration simpler and revenue collection more efficient. It is worth noting that the empire also went through some political important political changes.


The empire also had administrational changes Rome was the main political capital only until 286 AD. After this date the Tetarchy was established and other centres were founded, this continued until 286 AD. This was when Constantine declared Constantinople as the new Imperial capital, by this time the city of Rome had became the cultural and religious centre, as power was transferred to the regions. Constantine effectively split the empire into two states, the Eastern and Western Empires, to provide some political stability a western capital was founded, first at Milan (Mediolanum), which later transferred to Ravenna around 867 AD.

The Second division of the province of Britain in 293 AD, by Emperor Diocletian

The Province is divided by Emperor Diocletian in 293 AD, into four provinces in line with the original division. The south where the population had readily adopted Roman ways and were now self governing. This further reorganisation created of the province created the following administrative areas -

The Province of Maxima Caesariensis was the title given to the and most southerly and most important administrative region of Britannia.

From 293 AD, to 419 AD.

The Provincial Capital was Londinium - London.

The Province of Britannia Prima was the title of the second, southern administration region of the Province.

From 293 AD, to 419 AD.

The Provincial Capital was Corinium - Cirencester.
¹⁷

In the north almost all the population had now adopted Roman ways, however the area still had a strong military presence and there were patrols frequently sent into the border zone beyond the Hadrian’s wall. There were still a strong garrison forces established at bases such as Eboracum - York, Lindum - Lincoln and the bases and garrisons along Hadrian’s Wall. The provinces were as follows -

The Province of Flavia Caesariensis was the title of the new northern administration region of the Province.

From 293 AD, to 419 AD.

The Provincial Capital was Lindum - Lincoln.¹⁸

The Province of Britannia Secunda was the title of the most northerly administrative region of the Province.

From 293 AD, to 419 AD.

The Provincial Capital was Eboracum - York.

The Addition of The Province of Velantia in 369 AD, by Emperor Valentinian

This Province was created by the emperor Valentinian with the express purpose of extending Roman rule into the area north of Hadrian’s wall. There was still a hope that the tribes between the walls, those of the Votadini, Selgovae and Novantae¹⁹ could be once again part of Rome. There was no attempt to expand the empire beyond the line drawn between Falkirk and Glasgow. This province was -

The Military Province of Velantia This was administered by military commander under the direction of Rome.

From 369 AD, to the final withdrawal of Roman forces from Britannia.

A Provincial Capital was not created as this was a military province.

Although the system of Roman government in Britain was the same basic form used throughout the empire, it developed some unique differences. Britain had a ruling class that had remained mainly pagan despite the fact Christianity had become the official religion of the empire. The inhabitants of the province had also retained the same social structure that the Anglo Saxons, this meant the rural communities were almost the same as those of the raiders.


It was because of this similarity that when the raiding started towards the end of Roman occupation, many of the raiders found it possible to settle into the established communities. Later peoples who had arrived as mercenaries, originally hired by regional Nobles or communities to replace the departed legions, settled and became part of the community.


It is a tribute to the flexible nature of Roman rule that it was possible for the original inhabitants to retain their Celtic traditions while being part of the empire. This assisted the eventual transition into the independent kingdoms of the Saxon Heptarchy.
