After detaching from the kingdom various outlying districts, which could be conveniently absorbed into their own territories, they divided the rest of the country into two unequal portions.

The smaller of these, which comprised the more western districts, was placed under the protection of Rome, and was committed by Theodosius to the Arsaces who had been made king by Manuel, the son of the unfortunate Bab, or Para, and the grandson of the Arsaces contemporary with Julian.

The larger portion, which consisted of the regions lying towards the east, passed under the suzerainty of Persia, and was confided by Sapor III., who had succeeded Artaxerxes II., to an Arsacid, named Chosroes, a Christian, who was given the title of king, and received in marriage at the same time one of Sapor's sisters.
Such were the terms on which Rome and Persia brought their contention respecting Armenia to a conclusion.

Friendly relations were in this way established between the two crowns, which continued undisturbed for the long space of thirty-six years (A.D.

384-420).
