But Mebodes, the Grand Vizier, interposed with the assertion of a constitutional axiom, that no one had the right of taking the Persian crown until it was assigned to him by the assembly of the nobles.

Kaoses, who thought he might count on the goodwill of the nobles, acquiesced; and the assembly being convened, his claims were submitted to it.

Hereupon Mebodes brought forward the formal testament of Kobad, which he had hitherto concealed, and, submitting it to the nobles, exhorted them to accept as king the brave prince designated by a brave and successful father.

His eloquence and authority prevailed; the claims of Kaoses and of at least one other son of Kobad were set aside; and, in accordance with his father's will, Chosroes was proclaimed lawful monarch of Persia.
But a party among the nobles were dissatisfied with the decision to which the majority had come.

They dreaded the restlessness, and probably feared the cruelty, of Chosroes.
