Whether the Hephthalites wanted heavier payment for their assistance than had been previously agreed upon, or whether Peroz did not keep promises he had actually made, the end was that great conflicts ensued between them and the Persians. Peroz won some victories; but in the desert country east of the Caspian Sea the conduct of war is hampered by enormous difficulties. Twice he was compelled to conclude peace on unfavourable terms, once at least he himself fell into the hands of his enemies, and for two years his son Kavadh had to remain in the enemy’s camp as a hostage for the payment of his heavy ransom. Nevertheless Peroz was perpetually breaking the pledges he had given. In 484 he took the field with a large army. A tremendous battle ensued, in which Peroz perished among the unrecognised slain. His daughter was among the prisoners, and the king of the Hephthalites took her into his harem. Evil days were now in store for Persia. The victors overran the country. For a time there was no king. Presently, however, Zarmihr, of the powerful house of the Karen, succeeded in restoring order in the empire. At the time of Peroz’s death this man had been in Armenia, which had rebelled again, and had almost completed its subjugation. He then hastened to the capital and installed Balash, a brother of the late ruler, as king. In all probability he afterward entered into negotiations with the victorious enemy, and bought him off with a yearly tribute. A brother of Balash, Zareh by name, who likewise aspired to the crown, was defeated and slain. The king, however, had but little authority. He was obliged to induce the Armenians to submit by allowing them to exclude the state religion of Persia from their country altogether. The praise which the Syrians and the Armenians render to Balash’s clemency may perhaps have no other foundation than his disagreements with the priests of Zoroaster. The enmity thus aroused proved fatal to him. His treasury, of course, was empty, so that he could neither form a party among the nobles nor attach an army to himself; and in 488 or 489 the priests went so far as to have him blinded and so made incapable of governing. For according to the law of Persia no man could be king who was not whole and sound in body and mind. KAVADH I [Sidenote: [489-506 A.D.]]
