Central Intelligence Agency: Georgia in the World Factbook

Central Intelligence Agency: Georgia in the World Factbook: The region of present-day Georgia contained the ancient kingdoms of Colchis and Kartli-Iberia. The area came under Roman influence in the first centuries A.D. and Christianity became the state religion in the 330s. Domination by Persians, Arabs, and Turks was followed by a Georgian golden age (11th-13th centuries) that was cut short by the Mongol invasion of 1236. https://www.cia.gov/library/publications/the-world-factbook/geos/gg.html
