The First historical records about the Jewish presence in Armenia come from the 1st century B.C. One city, in particular, Vartkesavan-nowadays Echmiatsin became an important commercial center. By 360-370 AD, there was a massive increase in Jewish Hellenistic immigration into Armenia; many Armenian towns became predominately Jewish. In the 4th century, Sassanid King Shapur II deported thousands of Jewish families from Persian Armenia and resettled them at Isfahan. Jewish families were deported to Armenia and settled in Artashat, Vaghasabat, Yervandashat, Sarehavan, Sarisat, Van, and Nakhichevan.
