Georgian sources also refer to the arrival of the first Jews in Western Georgia from the Byzantine Empire during the 6th century CE. Approximately 3,000 of the Jews fled to Eastern Georgia, which by that time was controlled by the Persians, to escape severe persecution by the Byzantines. The existence of the Jews in these regions during this period is supported by the archaeological evidence, which shows that Jews lived in Mtskheta, the ancient capital of the Eastern Georgian state of Iberia-Kartli.
