Pacorus must have died about A.D. 108, or a little later. He left behind him two sons, Exedares and Parthamasiris, but neither of these two princes was allowed to succeed him. The Parthian Megistanes assigned the crown to Chosroes, the brother of their late monarch, perhaps regarding Exedares and Parthamasiris as too young to administer the government of Parthia satisfactorily. If they knew, as perhaps they did, that the long period of peace with Rome was coming to an end, and that they might expect shortly to be once more attacked by their old enemy, they might well desire to have upon the throne a prince of ripe years and approved judgment. A raw youth would certainly have been unfit to cope with the age, the experience, and the military genius of Trajan. CHAPTER XVIII. _Reign of Chosroes.

Death of Chosroes and Accession of Volagases II._ The general state of Oriental affairs at the accession of Chosroes seems to have been the following. Upon the demise of Tiridates (about A.D. 100) Pacorus had established upon the Armenian throne one of his sons, named Exedares, or Axidares, and this prince had thenceforth reigned as king of Armenia without making any application to Rome for investiture, or acknowledging in any way the right of the Romans to interfere with the Armenian succession. Trajan, sufficiently occupied in the West, had borne this insult. When, however, in A.D. 114, the subjugation of Dacia was completed, and the Roman Emperor found his hands free, he resolved to turn his arms towards Asia, and to make the Armenian difficulty a pretext for a great military expedition, designed to establish unmistakably the supremacy of Rome throughout the East. The condition of the East at once called for the attention of Rome, and was eminently favorable for the extension of her influence at this period. Disintegrating forces were everywhere at work, tending to produce a confusion and anarchy which invited the interposition of a great power, and rendered resistance to such a power difficult. Christianity, which was daily spreading itself more and more widely, acted as a dissolvent upon the previously-existing forms of society, loosening the old ties, dividing man from man by an irreconcilable division, and not giving much indication as yet of its power to combine and unite. Judaism, embittered by persecution, had from a nationality become a conspiracy; and the disaffected adherents of the Mosaic system, dispersed through all the countries of the East, formed an explosive element in the population which involved the constant danger of a catastrophe.
