The Roman provinces (Latin: provincia, 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 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 imperial dioceses (in turn subdivisions of the imperial prefectures).

History

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.

During the republic and early empire, provinces were generally governed by politicians of senatorial rank, usually former consuls 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 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 period

The English word province comes from the Latin word provincia. The Latin term provincia had an equivalent in eastern, Greek-speaking parts of the Greco-Roman world. In the Greek language, a province was called an eparchy (Greek: ἐπαρχίᾱ, eparchia), with a governor called an eparch (Greek: ἔπαρχος, eparchos).
