32. YESDIJIRD or JESDIGERD III., the last king, and said to be a grandson of Chosroes, reigned from A. D. 632 till 651. Having declined to adopt the Mohammedan religion, as he was summoned to do by the khalif Abu-Bekr, his kingdom was invaded by the Arabic general Kaleb.
In the battle of Cadesia (636), and other engagements, the Persians were worsted; their fortified towns and royal cities were taken one after the other; and, in 651, Jesdigerd was an abandoned fugitive in the tract watered by the Oxus and the Jaxartes, whence he solicited and, perhaps, obtained the assistance of Tait-Song, emperor of China.
He was thus enabled to raise an army of Turks, with whom he marched against the Arabs; but he was betrayed by his allies, by whom he was cut to pieces on his flight from them to the north.
He left a son, Firuz, or Peroses, who entered the service of the Chinese emperor; and his son, the last of the Sassanidae, was raised by the same to the rank of a vassal king of Bokhara.
A daughter of Jesdigerd married Hassan, the son of Ali; and another married Mohammed, the son of Abu-Bekr; important events for the later history of Persia, which was henceforth a Mohammedan country.
We observe here that the Persian historians are respectable sources for the history of the Sassanidae, and that their chronology differs but little from that of the Western writers.
