Roman Georgia refers to the area of Georgia that was under Roman control. Between the 1st century BC and the 7th century AD Rome, at certain times, intermittently controlled directly or indirectly the kingdoms of Colchis and Iberia in the Caucasus region (corresponding approximately to western and eastern contemporary Georgia).
Rome's conquests reached the Caucasus area at the end of the 2nd century BC, when the Roman Republic started to expand in Anatolia and the Black Sea.
In the area of what is now western Georgia there was the Kingdom of Colchis that in those years had fallen under control of the Kingdom of Pontus (an enemy of Rome), while further east there was the "Kingdom of Iberia". As a result of the Roman campaigns of Pompey and Lucullus in 65 BC, the Kingdom of Pontus was completely destroyed by the Romans and all its territory, including Colchis, was incorporated into the Roman Empire as its province. Iberia, on the other hand was invaded and became a vassal state of the empire.
From this point on Colchis became the Roman province of Lazicum, with Emperor Nero later incorporating it into the Province of Pontus in 63 AD, and successively in Cappadocia by Domitian in 81 AD. At the same time, Iberia continued to be a vassal state because it enjoyed significant independence and with the lowlands frequently raided by fierce mountain tribes, paying a nominal homage to Rome in exchange of protection was viewed as a worthwhile investment.
