The family was native to
Daylam. During their early period, the family held much influence over the districts of Shukur, Ranikuh and Ashkawar in Tabaristan. The first member of the family was a certain Nu'man, who had two sons named
Kaki and
Fairuzan, whom both served the
Alid dynasties of northern Iran. In 902, both of them were killed during a
Samanid invasion of Tabaristan. Both of the slain brothers had a son; Kaki had a son named
Makan ibn Kaki, while Fairuzan had a son named
Al-Hasan ibn al-Fairuzan. Both of these sons would later play an important role in the politics of northern Iran. Makan later managed to make the Alid ruler his puppet, and make Tabaristan part of his domains. However, other Daylamites such as
Asfar ibn Shiruya, including the Daylamite
Buyids and
Ziyarids, and the
Persian Samanid dynasty, claimed suzerainty over Tabaristan, which in the end resulted in Makan getting killed in 940 by a Samanid army. Makan had a son named
Ibn Makan, who later tried to seize
Isfahan from the Buyids, but was defeated, and thereafter disappears from history chronicles. Al-Hasan managed to survive the struggle, and had two sons named
Firuzan ibn al-Hasan and
Nasr ibn al-Hasan. According to the historian
Ibn Isfandiyar, Firuzan ruled Daylam, while Nasr ruled
Qumis. Nasr is said to have built the
Shahdiz in ca. 970, which would later become an important
Ismaili fortress. Nasr later fell out of favor from the Ziyarid ruler
Qabus, and was imprisoned. The fate of his brother is unknown. Nasr had a son named
Hazarasp ibn Nasr, who served as a Buyid military officer. After this, the family disappears from history chronicles. ==Sources==
