His nephew, Kavadh I, the son of Peroz, was set in his place. He found the empire in a state of great disorder. We hear of revolts of savage mountain tribes, and of another rebellion in Armenia. Kavadh, who had no inclination to play the obedient servant to the tyrants who had raised him to the throne, adopted a dangerous method of weakening the power of priests and nobles; for he favoured Mazdak, a zealous preacher of religious-socialistic doctrines, who demanded in the name of justice that he who was blest with riches and possessed of many wives should give of his superfluity to those who were in want. Nor did he rest satisfied with the theory, for many of his disciples distributed their wives and goods. But the nobles and clergy united to depose Kavadh, imprisoned him in the “castle of oblivion,” and bestowed the crown on his brother Jamasp (about 496). Kavadh, however, escaped, and fled to the Hephthalites, among whom he had formerly lived as a hostage. The king gave him his daughter to wife, the child of that sister of Kavadh who had been taken in battle; and by the help of the barbarian prince he succeeded in overthrowing Jamasp and once more becoming king of Persia (498 or 499). His flight and restoration appear to have been favoured by some of the most powerful nobles. According to Persian tradition Zarmihr actually accompanied him into exile, but such testimony as we have concerning this man and the flight to the Hephthalites is so confused that we can place no reliance upon it. Certain it is that after his return the king visited his enemies with severe chastisement. Presumably he abandoned Zarmihr about that time, for he handed him over to his most formidable rival, Sapor, of the house of Mihran. It is not likely that Kavadh then resumed his experiment with the Mazdakites. NEW CONFLICT WITH ROME He had certainly reduced the empire to tolerable order by the time the war with the Romans began. There had been much treating over terms, both parties had violated compacts more or less, and the only question was whether either of them was desirous of finding a _casus belli_. This was the case with Kavadh. In the summer of 502 he inaugurated that era of hideous strife which so reduced the strength of both Persia and Eastern Rome as to make possible the subsequent victories of the Arabs. In August he took Theodosiopolis (Karin or Erzerum), the capital of Roman Armenia, without a blow. On the 10th of January, 503, Amida fell after a three months’ siege, and was frightfully punished for its resistance. Myriads of the inhabitants were slaughtered, as we know from the good accounts we have in existing contemporary Syrian sources.
