A later exception was the province of Egypt, incorporated by Augustus after the death of Cleopatra: it was ruled by a governor of equestrian rank only, perhaps as a discouragement to senatorial ambition.

Republican provinces

The term provincia originally designated simply a task or duty within the Roman state. Under the Roman Republic, the magistrates were elected to office for a period of one year, and those serving outside the city of Rome, like the consuls on campaign, were assigned a particular "province", an area of authority. The term did not acquire a definite territorial sense until Rome started expanding beyond Italy during the First Punic War
