Meantime a powerful Roman army under Count Trajan, and the chief Persian host, had actually camped opposite each other on the borders of Armenia (371); but neither side wanted a general war just then,--Rome must have her hands free for the Goths, and Persia hers for the Mongols. Finally, in 379, Shahpur died, and there was an instant and entire change in Persian policy toward Rome, and even toward Christianity for a while. His brother and successor, Ardashir, was an old man, and reigned but four years; his successor, Shahpur III, at once sent embassies to Rome, and made a treaty of peace (384). Finally, on the succession of Bahram IV (Kirman Shah), in 390, that monarch arranged a treaty of partition with Theodosius, the Roman emperor, by which Armenia ceased to exist. The western portion became a Roman province; the then reigning sovereign, Arshag IV, was made governor to keep the people contented. The eastern, and much the larger section, was annexed to Persia, under the name of Persarmenia; and to please the people, an Arsacid, Chosroes IV, was made governor, and the dynasty was continued in its rule over the Armenians till after the great Perso-Roman war of 421-2, and the persecution of Christians by Persia, which was the pretext of it. The persecution and the war led to a movement for Armenian independence; after it was over, Bahram V of Persia (Gor, the Wild Ass, "the mighty hunter") put a new vassal, Ardashes IV, into the governorship; but the great Armenian barons would not give up the struggle, and this last of the Arshagoonian dynasty was removed in 428 and Persian governors substituted. Thus ended the rule of the line of Arshag. It was a mighty race, and swarms with brilliant names; but in Persia it was justly displaced by one of better public policy, and in Armenia the position of the country was fatal to it.
