Farrukhzad (Farrūkhzādag; New Persian: فرخزاد) was an Iranian aristocrat from the House of Ispahbudhan and the founder of the Bavand dynasty, ruling from 651 to 665. Originally a powerful servant of the Sasanian king Khosrow II (r. 590–628), he, along with several other powerful aristocrats made a conspiracy against the latter and ended his tyrannical rule. They thereafter put Khosrow's son Kavadh II (r. 628) on the throne, whose rule lasted only a few months, before he was killed by a plague, being succeeded by his son Ardashir III (r. 628–629), who was only after one year murdered by the rebellious former Sasanian army chief (spahbed) Shahrbaraz, who usurped the throne.
These events greatly weakened the Sasanian Empire, but by 632, when Khosrow's grandson Yazdegerd III (r. 632–651) ascended the throne, order was somewhat restored. However, just as peace was about to come, the Sasanian Empire was invaded by Muslim Arabs, which resulted in the death of many Sasanian veterans, including Farrukhzad's brother Rostam Farrokhzad himself. Farrukhzad thereafter succeeded the latter as the spahbed and the leader of the Pahlav (Parthian) faction, which had been formed by their father Farrukh Hormizd, who was murdered in 631.
However, Farrukhzad was unable to defeat the Arabs, from one place to another until in 650, when Farrukhzad mutinied against his king, who was shortly killed by one of his servants. Farrukhzad later became the ruler of Tabaristan in 651, and would rule the region until his murder in 665 by Valash, a Karenid aristocrat, who thereafter conquered his domains.
Although his real name was "Farrukhzad" (meaning "the son of Farrukh" or "born with luck and happiness"), he is also known in other sources by various other names, such as Khurrazad, Zad Farrukh, Zinabi Abu'l-Farrukhan and Bav.
Farrukhzad was the son of Farrukh Hormizd, a prominent aristocrat from the Ispahbudhan family, who served as the army chief (spahbed) of the kusts of Adurbadagan and Khorasan—he was one of the generals who led the Sasanian army during the Byzantine–Sasanian War of 602–628, but in 626 along with his comrade Shahrbaraz rebelled against the Sasanian king Khosrow II (r.
