Terminology

The English word ''province'' comes from the Latin word ''provincia''. In early Republican times, the term was used as a common designation for any task or set of responsibilities assigned by the Roman Senate to an individual who held ''
imperium In ancient Rome, ''imperium'' was a form of authority held by a citizen to control a military or governmental entity. It is distinct from '' auctoritas'' and '' potestas'', different and generally inferior types of power in the Roman Republic a ...
'' (right of command), which was often a military command within a specified theatre of operations. In time, the term became the main designation for a territorial jurisdiction in newly acquired regions of the Roman Republic. The Latin term ''provincia'' had an equivalent in eastern, Greek-speaking parts of the Greco-Roman world. In the Greek language, province was called ''eparchy'' ( el, , ''eparchia''). That term was used both colloquially and officially, in Roman legal acts that were issued in the Greek language. In the same time, provincial governor was called ''eparch'' ( el, , ''eparchos'').


Overview

A province was the basic and, until the Tetrarchy (from AD 293), the largest territorial and administrative unit of the empire's territorial possessions outside Roman Italy. Provinces were generally governed by politicians of senatorial rank, usually former consuls or former
praetors Praetor ( , ), also pretor, was the title granted by the government of Ancient Rome to a man acting in one of two official capacities: (i) the commander of an army, and (ii) as an elected ''magistratus'' (magistrate), assigned to discharge variou ...
. A later exception was the province of Egypt, which was incorporated by
Augustus Caesar Augustus (born Gaius Octavius; 23 September 63 BC – 19 August AD 14), also known as Octavian, was the first Roman emperor; he reigned from 27 BC until his death in AD 14. He is known for being the founder of the Roman Pr ...
after the death of Cleopatra and was ruled by a governor of only equestrian 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.


Republican provinces

Under the
Roman Republic The Roman Republic ( la, Res publica Romana ) was a form of government of Rome and the era of the classical Roman civilization when it was run through public representation of the Roman people. Beginning with the overthrow of the Roman Ki ...
, the magistrates were elected to office for a period of one year, and those serving outside the city of Rome, such as consuls acting as generals on a military campaign, were assigned a particular ''provincia'', the scope of authority within which they exercised their command. The territory of a people who were defeated in war might be brought under various forms of treaty, in some cases entailing complete subjection ''( deditio)''. The formal annexation of a territory created a province, in the modern sense of an administrative unit that is geographically defined. Republican-period provinces were administered in one-year terms by the consuls and
praetors Praetor ( , ), also pretor, was the title granted by the government of Ancient Rome to a man acting in one of two official capacities: (i) the commander of an army, and (ii) as an elected ''magistratus'' (magistrate), assigned to discharge variou ...
who had held office the previous year and were invested with ''imperium''. Rome started expanding beyond Italy during the First Punic War. The first permanent provinces to be annexed were

in 241 BC and Sardinia and Corsica in 237 BC. Militarized expansionism kept increasing the number of these administrative provinces until there were no longer enough qualified individuals to fill the posts. The terms of provincial governors often had to be extended for multiple years ''(
prorogatio ''Prorogatio'' was a Roman practice in which a Roman magistrate's duties were extended beyond its normal annual term. It developed as a response to Roman expansion's demands for more generals and governors to administer conquered territories. Pr ...
)'', and on occasion, the Senate awarded ''imperium'' even to private citizens ''( privati)'', most notably Pompey the Great. Prorogation undermined the republican constitutional principle of annually-elected magistracies and the amassing of disproportionate wealth and military power by a few men through their provincial commands was a major factor in the transition from a republic to an imperial autocracy.

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 ', 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 '' duces'', in charge of border garrisons on so-called '' limites'', and the higher ranking ', with more mobile forces, and the later, even higher ''magistri militum''. Justinian I made the next great 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 extraordinary Exarchates in the 580s and culminated with the adoption of the military theme system in the 640s, which replaced the older administrative arrangements entirely.
