**Quhyar** (Persian: کوه یار), was the ruler of the [Qarinvand dynasty](/source/Qarinvand_dynasty), ruling briefly in 839 until his assassination.

## Biography

Quhyar was the son of Qarin ibn Vindadhhurmuzd, and had a brother named [Mazyar](/source/Mazyar), who, after ascending the Qarinvand throne, was repelled from [Tabaristan](/source/Tabaristan) by his uncle Vinda-Umid and the [Bavandid](/source/Bavandid) ruler [Shahriyar I](/source/Shahriyar_I). However, Mazyar returned in 822/23 with the support of the [Abbasid Caliphate](/source/Abbasid_Caliphate) to take revenge. [Shapur](/source/Shapur_(Bavandid_ruler)), who was the son and successor of Shahriyar I, was defeated and killed along with Vinda-Umid. Mazyar then united Tabaristan under his own rule.

Mazyar, however, later rebelled against the Abbasid Caliphate, an act which was widely supported by the native [Zoroastrians](/source/Zoroastrians), who began plundering the Muslim villages.[1] The [Tahirid](/source/Tahirid) ruler [Abdallah ibn Tahir al-Khurasani](/source/Abdallah_ibn_Tahir_al-Khurasani) and the Abbasid caliph [al-Mu'tasim](/source/Al-Mu'tasim) shortly sent five corps that entered Tabaristan from all sides. Mazyar made his brother Quhyar as the defender of the Qarinvand mountains, and the Bavandid [Qarin I](/source/Qarin_I) as the defender of eastern Tabaristan. However, the fall of Tabaristan went quickly: several cities were caught by surprise, while Qarin I betrayed Mazyar and agreed to aid the Abbasids in exchange for being restored as the ruler of the Bavand dynasty. The people of [Sari](/source/Sari,_Iran) shortly revolted against Mazyar, and Quhyar betrayed Mazyar, and had him captured and given to al-Mu'tasim.[2]

Mazyar was shortly brought to [Samarra](/source/Samarra), where he was executed. His body later became [gibbeted](/source/Gibbeting) with the body of the [Khurramite](/source/Khurramite) [Babak Khorramdin](/source/Babak_Khorramdin). Quhyar, who had just ascended the Qarinvand throne, however, was shortly killed by his own [Dailamite](/source/Dailamite) soldiers because of his betrayal against Mazyar. Although many scholars considered the death of Quhyar as the fall of the Qarinvand dynasty, the dynasty continued to rule in parts of Tabaristan, and a certain [Baduspan ibn Gurdzad](/source/Baduspan_ibn_Gurdzad) is mentioned in 864 as the ruler of the Qarinvand dynasty
