Al-Hasan ibn al-Fairuzan

Al-Hasan ibn al-Fairuzan (fl. 10th century) was a Daylamite prince from the Firuzanid family.

Al-Hasan was the son of Fairuzan, a Daylamite soldier, who along with his brother Kaki served the Alid dynasties of northern Iran. In 902, both of them were killed during a Samanid invasion of Tabaristan. Kaki had a son named Makan ibn Kaki, who together with al-Hasan served the Alids. Makan had established family ties through marriage with the Alids, as Ja'far, the son of imam Hasan ibn Ali al-Utrush (r. 914–917), was his son-in-law. The latter was engaged in a complex struggle against al-Utrush's designated successor Abu Muhammad Hasan ibn Qasim, known as the Da'i ila'l-Haqq (r. 917–928), and it was not until 923 that Ja'far and his brother Ahmad succeeded in ousting the Da'i and forcing him to exile. When Ja'far died in 924, he left the throne to Ahmad's son Abu Ali Muhammad, but al-Hasan and Makan deposed Muhammad and installed al-Hasan's half-brother Ismail, a son of Ja'far and the mother of al-Hasan, in his place. Muhammad, however, managed to escape from his captors and with the aid of the Gilaki military chief Asfar ibn Shiruya, who had seized control of Gurgan, defeated the two brothers and retook his throne.

In 930, Makan managed to recover Tabaristan, and appointed al-Hasan as the governor of the region. Makan also made Abu Muhammad Hasan ibn Qasim the imam of the Alids. A fake rumor later spread about the death of Makan, which made al-Hasan, who wanted to install his half-brother Ismail as the imam, rise into rebellion. However, the rebellion failed after Ismail was poisoned at the instigation of Abu Ja'far Husayn's mother. Al-Hasan was shortly driven out from Amol by two officers of Makan named Abu Ali and Abu Musa. Al-Hasan then fled to Daylam. Makan was himself shortly driven out from Tabaristan by the Ziyarid ruler Mardavij.
