In order to further reduce the political and economic power of Iranian Armenia, Shapur III deprived the country of several of its provinces; Artsakh, Utik, Shakashen, Gardman and Kolt were given to Caucasian Albania (ruled by a collateral line of the Arsacids); Gugark (ruled by the Mihranids) became subject to Iberia; and Arzanene (ruled by a "bidaxsh", i.e. margrave), Paytakaran, Korjayk (Corduene) and Parskahayk were incorporated into Iran. Arshak III soon died, which made the Romans abolish their branch of the Arsacid monarchy and create the province of Western Armenia. As a result many of the "nakharars" who had followed him subsequently rejoined the Iranians. The Arsacid monarchy in Iranian Armenia continued to last for a few decades, until its abolishment by king Bahram V () in 428. Shapur III's religious tolerance towards the Christians is reported by the historians Elishe and John of Ephesus. According to the former, Shapur III granted the Armenians lavish gifts and exempted their Church from royal taxation.
