SENATORIAL PROVINCE

A 'senatorial province' was a Roman province where the Roman Senate had the right to appoint governors. These provinces were away from the Empire's borders and free from the likelihood of rebellion, and so had few if any legions stationed in them (thus lessening the chance the Senate might try to seize power from the Emperor). They were often along the Mediterranean Sea.
The provinces were grouped into imperial provinces and senatorial provinces shortly after the accession of Augustus.
In 14 the following provinces were senatorial provinces:

★ Achaea

★ Africa

★ Asia

★ Creta et Cyrene

★ Cyprus

★ Gallia Narbonensis

★ Hispania Baetica

★ Macedonia (Macedonia & Thessalia)

★ Pontus et Bithynia

★ Sicilia
