The Roman invasions are responsible for bringing about a significant increase in olive oil production beginning between Punic and Macedonian wars of the Roman Republic in the II century BC and II century AD when the empire reached its greatest territorial extent under the emperor Trajan in 117 AD.
Olive oil production became semi-industrialized at sites such as Hendek Kale in Turkey, Byzacena in Tunisia and Tripolitania, in Libya, where 750 separate olive oil production sites have been identified. Production estimates of oil are up to 30 million liters (8 million gallons) per year from Tripolitania, and up to 40 million li (10.5 million gal) from Byzacena. Plutarch reports that Caesar forced Tripolitania's inhabitants to pay a tribute of 1 million li (250,000 gal) in 46 BC. Oileries are also reported from the first and second centuries AD in the Guadalquivir valley of Andalusia in Spain, where average annual yields were estimated between 20 and 100 million li (5-26 million gal). Archaeological investigations at Monte Testaccio recovered evidence suggesting that Rome imported approximately 6.5 billion liters of olive oil over the period of 260 years. more here
