Аршакуни
Under the rule of the Arsacid dynasty of Armenia (54–428 AD), many other cities around Erebuni including Vagharshapat and Dvin flourished. Consequently, Erebuni was completely neutralized, losing its role as an economic and strategic centre of Armenia. During the period of the Arsacid kings, Erebuni was only recorded in a Manichaean text of the 3rd century, where it is mentioned that one of the disciples of the prophet Mani founded a Manichaean community near the Christian community in Erebuni.
