Roman Province - Imperial Provinces During The Principate

Imperial Provinces During The Principate

In the so-called Augustan Settlement of 27 BC, which established the Roman Empire, the governance of the provinces was regulated. Octavian Caesar, having emerged from the Roman civil wars as the undisputed victor and master of the Roman state, officially laid down his powers, and in theory restored the authority of the Roman Senate. Octavian himself assumed the title "Augustus" and was given to govern, in addition to Egypt, the strategically important provinces of Gaul, Hispania and Syria (including Cilicia and Cyprus). Under Augustus, Roman provinces were classified as either senatorial or imperial, meaning that their governors were appointed by either the Senate or by the emperor. Generally, the older provinces that existed under the Republic were senatorial. Senatorial provinces were, as before under the Republic, governed by a proconsul, who was chosen by lot among the ranks of senators who were ex-consuls or ex-praetors, depending on which province was assigned. The major imperial provinces were under a legatus Augusti pro praetore, also a senator of consular or praetorian rank. Egypt and some smaller provinces where no legions were based were ruled by a procurator (praefectus in Egypt), whom the emperor selected from non-senators of equestrian rank. The status of a province could change from time to time. In AD 68, of a total 36 provinces, 11 were senatorial and 25 imperial. Of the latter, 15 were under legati and 10 under procuratores or praefecti.

During the Principate, the number and size of provinces also changed, either through conquest or through the division of existing provinces. The larger or more heavily garrisoned provinces (for example Syria and Moesia) were subdivided into smaller provinces to prevent any single governor from holding too much power.
