Bahram V, king of Persia (420-439), son of Yazdegerd I, after whose sudden death (or assassination) he gained the crown against the opposition of the grandees by the help of al-Mondhir , the Arabic dynast of Hira. Bahram's mother was Soshandukht, the daughter of the Jewish Exilarch.

He promised to rule otherwise than his father, who had been very energetic and at the same time tolerant in religion. So Bahram V began a systematic persecution of the Christians, which led to a war with the Roman empire. But he had little success, and soon concluded a treaty by which both empires promised toleration to the worshippers of the two rival religions, Christianity and Zoroastrianism.

Bahram deposed the vassal king of the Persian part of Armenia and made it a province. He is a great favourite in Persian tradition, which relates many stories of his valour and beauty, of his victories over the Romans, Turks, Indians and Africans, and of his adventures in hunting and in love; he is called Bahram Gur, "Zebra," on account of his love for hunting, and in particular, huting zebras.

In reality he seems to have been rather a weak monarch, after the heart of the grandees and the priests. He is said to have built many great fire-temples, with large gardens and villages (Tabari).
