The Roman provinces (, pl. provinciae) were the administrative regions of Ancient Rome outside Roman Italy that were controlled by the Romans under the Roman Republic and later the Roman Empire. Each province was ruled by a Roman appointed as Roman governor.
For centuries, it was the largest administrative unit of the foreign possessions of ancient Rome. With the administrative reform initiated by Diocletian, it became a third level administrative subdivision of the Roman Empire, or rather a subdivision of the Roman diocese (in turn subdivisions of the imperial prefectures).
During the republic and early empire, provinces were generally governed by politicians of Roman senate rank, usually former Roman consul or former praetors. A later exception was the province of Egypt, which was incorporated by Augustus after the death of Cleopatra and was ruled by a governor of only equestrian order rank, perhaps as a discouragement to senatorial ambition. That exception was unique but not contrary to Roman law, as Egypt was considered Augustus's personal property, following the tradition of the kings of the earlier Hellenistic period.
The first commanders dispatched with provinciae were for the purpose of waging war and to command an army. However, merely that a provincia was assigned did not mean the Romans made that territory theirs. For example, Publius Sulpicius Galba Maximus in 211 BC received Macedonia as his provincia but the republic did not annex the kingdom, even as Macedonia was continuously assigned until 205 BC with the end of the First Macedonian War. Even though the Second and Third Macedonian Wars saw the Macedonian province revived, the senate settled affairs in the region by abolishing Macedonia and replacing it with four client republics. Macedonia only came under direct Roman administration in the aftermath of the Fourth Macedonian War in 148 BC. Similarly, assignment of various provinciae in Hispania was not accompanied by the creation of any regular administration of the area; indeed, even though two praetors were assigned to Hispania regularly from 196 BC, no systematic settlement of the region occurred for nearly thirty years and what administration occurred was ad hoc and emerged from military necessities.
In the middle republic, the administration of a territory – whether taxation or jurisdiction – had basically no relationship with whether that place was assigned as a provincia by the senate. Rome would even intervene on territorial disputes which were part of no provincia at all and were not administered by Rome. The territorial province, called a "permanent" provincia in the scholarship, emerged only gradually.
Only around 180 BC did provinces take on a more geographically defined position when a border was established to separate the two commanders assigned to Hispania on the river Guadalquivir. Later provinces, once campaigns were complete, were all largely defined geographically. Once this division of permanent and temporary provinciae emerged, magistrates assigned to permanent provinces also came under pressures to achieve as much as possible during their terms. Whenever a military crisis occurred near some province, it was normally reassigned to one of the consuls; praetors were left with the garrison duties. In the permanent provinces, the Roman commanders were initially not intended as administrators. However, the presence of the commander with forces sufficient to coerce compliance made him an obvious place to seek final judgement. A governor's legal jurisdiction thus grew from the demands of the provincial inhabitants for authoritative settlement of disputes.
In the absence of opportunities for conquest and with little oversight for their activities, many praetorian governors settled on extorting the provincials. This profiteering threatened Roman control by unnecessarily angering the province's subject populations and was regardless dishonourable. It eventually drew a reaction from the senate, which reacted with laws to rein in the governors. After initial experimentation with ad hoc panels of inquest, various laws were passed, such as the lex Calpurnia de repetundis in 149 BC, which established a permanent court to try corruption cases; troubles with corruption and laws reacting to it continued through the republican era. By the end of the republic, a multitude of laws had been passed on how a governor would complete his task, requiring presence in the province, regulating how he could requisition goods from provincial communities, limiting the number of years he could serve in the province, etc.
While many of the provinces had been assigned to sitting praetors in the earlier part of the second century, with new praetorships created to fill empty provincial commands, by the start of the first century it had become uncommon for praetors to hold provincial commands during their formal annual term. Instead they generally took command as promagistrate after the end of their term. The use of prorogation was due to an insufficient number of praetors, which was for two reasons: more provinces needed commands and the increased number of permanent jury courts ( quaestiones perpetuae), each of which had a praetor as president, exacerbated this issue.. Formally, the presidency of one of the permanent courts was in fact the provincia of the praetor-president. Praetors during the second century were normally prorogued pro praetore, but starting with the Spanish provinces and expanding by 167 BC, praetors were more commonly prorogued with the augmented rank proconsul; by the end of the republic, all governors acted pro consule.
Also important was the assertion of popular authority over the assignment of provincial commands. This started with Gaius Marius, who had an allied tribune introduce a law transferring to him the already-taken province of Numidia (then held by Quintus Caecilius Metellus), allowing Marius to assume command of the Jugurthine War. This innovation destabilised the system of assigning provincial commands, exacerbated internal political tensions, and later allowed ambitious politicians to assemble for themselves enormous commands which the senate would never have approved: the Pompeian lex Gabinia of 67 BC granted Pompey all land within 50 miles of the Mediterranean; Caesar's Gallic command that encompassed three normal provinces.
The senate attempted to push back against these commands in many instances: it preferred to break up any large war into multiple territorially separated commands; for similar reasons, it opposed the lex Gabinia which gave Pompey an overlapping command over large portions of the Mediterranean. The senate, which had long acted as a check on aristocratic ambitions, was unable to stop these immense commands, which culminated eventually with the reduction of the number of meaningfully-independent governors during the triumviral period to three men and, with the end of the republic, to one man.
The provinces that were assigned to Augustus became known as imperial provinces and the remaining provinces, largely demilitarised and confined to the older republican conquests, became known as public or senatorial provinces, as their commanders were still assigned by the senate on an annual basis consistent with tradition. Because no one man could command in practically all the border-regions of the empire at once, Augustus appointed subordinate Legatus for each of the provinces with the title legatus Augusti pro praetore. These lieutenant legati probably held imperium but, due to their lack of an independent command, were unable to triumph and could be replaced by their superior (Augustus) at any time. These arrangements were likely based on the precedent of Pompey's proconsulship over the Spanish provinces after 55 BC entirely through legates, while he stayed in the vicinity of Rome. In contrast, the public provinces continued to be governed by proconsuls with formally independent commands. In only three of the public provinces were there any armies: Africa, Illyricum, and Macedonia; after Augustus' Balkan wars, only Africa retained a legion.
To make this monopolisation of military commands palatable, Augustus separated prestige from military importance and inverted it. The title pro praetore had gone out of use by the end of the republic and was regardless in inferior status to a proconsul. More radically, Egypt (which was sufficiently powerful that a commander there could start a rebellion against the emperor) was commanded by an equestrian prefect, "a very low title indeed" as prefects were normally low-ranking officers and equestrians were not normally part of the elite. In Augustus' "second settlement" of 23 BC, he gave up his continual holding of the consulship in exchange for a general proconsulship – with a special dispensation from the law that nullified imperium within the city of Rome – over the imperial provinces. He also gave himself, through the senate, a general grant of imperium maius, which gave him priority over the ordinary governors of the public provinces, allowing him to interfere in their affairs.
Within the public and imperial provinces there also existed distinctions of rank. In the public provinces, the provinces of Africa and Asia were given only to ex-consuls; ex-praetors received the others. The imperial provinces eventually produced a three-tier system with prefects and procurators, legates pro praetore who were ex-praetors, and legates pro praetore who were ex-consuls. The public provinces' governors normally served only one year; the imperial provinces' governors on the other hand normally served several years before rotating out. The extent to which the emperor exercised control over all the provinces increased during the imperial period: Tiberius, for example, once reprimanded legates in the imperial provinces for failing to forward financial reports to the senate; by the reign of Claudius, however, the senatorial provinces' proconsuls were regularly issued with orders directly from the emperor.
Although the Caesars were soon eliminated from the picture, the four administrative resorts were restored in 318 by Emperor Constantine I, in the form of praetorian prefectures, whose holders generally rotated frequently, as in the usual magistracies but without a colleague. Constantine also created a new capital, named after him as Constantinople, which was sometimes called 'New Rome' because it became the permanent seat of the government. In Italy itself, Rome had not been the imperial residence for some time and 286 Diocletian formally moved the seat of government to Mediolanum (modern Milan), while taking up residence himself in Nicomedia. During the 4th century, the administrative structure was modified several times, including repeated experiments with Eastern-Western co-emperors.Nuovo Atlante Storico De Agostini, 1997, pp. 40–41. (In Italian)
Detailed information on the arrangements during this period is contained in the Notitia Dignitatum (Record of Offices), a document dating from the early 5th century. Most data is drawn from this authentic imperial source, as the names of the areas governed and titles of the governors are given there. There are however debates about the source of some data recorded in the Notitia, and it seems clear that some of its own sources are earlier than others. Some scholars compare this with the list of military territories under the Dux, in charge of border garrisons on so-called limites, and the higher ranking Comites rei militaris, with more mobile forces, and the later, even higher Magister Militum.
Justinian I made the next changes in 534–536 by abolishing, in some provinces, the strict separation of civil and military authority that Diocletian had established. This process was continued on a larger scale with the creation of in the 580s and culminated with the adoption of the military theme system in the 640s, which replaced the older administrative arrangements entirely. Some scholars use the reorganization of the empire into themata in this period as one of the demarcations between the Dominate and the Byzantine (or the Later Roman) period.
