**Qarin I** ([Persian](/source/Persian_language): کارن), was the eighth ruler of the [Bavand dynasty](/source/Bavand_dynasty) from 839 to 867.

## Biography

His brother, [Shapur](/source/Shapur_(Bavandid_ruler)), was murdered in 825 by a [Qarinvand](/source/Qarinvand) named [Mazyar](/source/Mazyar), who then conquered his domains. With the aid of [Abbasids](/source/Abbasids) and [Tahirids](/source/Tahirids), however, Qarin managed to reclaim his domains from Mazyar. During the same period, Mazyar was betrayed by his brother [Quhyar](/source/Quhyar), and was sentenced to death in [Baghdad](/source/Baghdad). In 842, Qarin converted to [Islam](/source/Islam),[1][2] where he was rewarded with the title of **Abu'l-Muluk**.

In the 860s, western Iran was governed by the Tahirid [Muhammad ibn Abdallah ibn Tahir](/source/Muhammad_ibn_Abdallah_ibn_Tahir), whose brother [Sulayman ibn Abdallah ibn Tahir](/source/Sulayman_ibn_Abdallah_ibn_Tahir) deputized him in [Tabaristan](/source/Tabaristan) and [Gurgan](/source/Gurgan). Popular resentment of the Tahirids' rule increased through the oppression of their officials, especially their fiscal agents in the province. Consequently, in 864 a rebellion broke out in the towns of [Ruyan](/source/Royan,_Iran), Kalar and [Chalus](/source/Chalus,_Iran), led by two "sons of [Rostam](/source/Rostam)". The rebels called upon [Hasan ibn Zayd](/source/Hasan_ibn_Zayd), an [Alid](/source/Alids), to lead them, and allied themselves with the neighbouring [Dailamites](/source/Dailamites). Hasan, who assumed the [regnal name](/source/Laqab) *al-Da‘ī ila’l-ḥaqq* ("He who summons to the Truth"), was recognized as [emir](/source/Emir) by a part of the local population, and even secured the allegiance of the [Justanid](/source/Justanid) king of [Daylam](/source/Daylam), [Vahsudan ibn Marzuban](/source/Vahsudan_ibn_Marzuban).[3][4][2] Qarin, however, opposed [Zaydid](/source/Zaydid) rule in Tabaristan, and allied himself with Sulayman ibn Abdallah ibn Tahir against Hasan, but was defeated by Hasan in a battle, who had Qarin's domains devastated and his brother [Ja'far ibn Shahriyar](/source/Ja'far_ibn_Shahriyar) killed. Qarin then had to swear loyalty to the Zaydids and send his two sons [Surkhab ibn Qarin](/source/Surkhab_ibn_Qarin) and [Maziar ibn Qarin](/source/Maziar_ibn_Qarin) as hostages to the Zaydid court, but quickly mutinied against Hasan, and in 868, he was forced to flee to [Kumis](/source/Qumis,_Iran).[1] Qarin I died in 867, and was succeeded by his son or grandson [Rustam I](/source/Rustam_I).
