Foreign domination

Tbilisi's favorable trade location, however, did not necessarily bode well for its survival. Located strategically in the heart of the Caucasus between Europe and Asia, Tbilisi became an object of rivalry among the region's various powers such as the Roman Empire, Parthia, Sassanid Persia, Muslim Arabs, the Byzantine Empire, and the Seljuk Turks. The cultural development of the city was somewhat dependent on who ruled the city at various times, although Tbilisi was fairly cosmopolitan.

From 570 to 580, the Persians ruled the city until 627, when Tbilisi was sacked by the Byzantine / Khazar armies and later, in 736–738, Arab armies entered the town under Marwan II. After this point, the Arabs established an emirate centered in Tbilisi. Arabic dirhams were brought to Georgia following the Arab conquest in the seventh century, and a mint was founded in Tbilisi that produced coins with inscriptions in both Arabic and Georgian. In 764, Tbilisi – still under Arab control – was once again sacked by the Khazars. In 853, the armies of Arab leader Bugha Al-Turki invaded Tbilisi in order to enforce its return to Abbasid allegiance. The Arab domination of Tbilisi continued until about 1050. In 1065, the Seljuk Sultan Alp Arslan campaigned against the Kingdom of Georgia, subjugated Tbilisi, and built a mosque in the city.
