Vushmgir

He belonged to the Arghich tribe, which claimed to be descended from Arghush Farhadan, king of Gilan who lived during the time of Kai Khosrow.

Vushmgir is most commonly considered to have been a Muslim, particularly Zaydi Shiite, but he has also been described as Zoroastrian at least in his earlier years.

In 931, Mardavij, the brother of Vushmgir and king of the Ziyarid dynasty, sent an army to conquer Tabaristan from Makan ibn Kaki, but was defeated.

Many of the Turks then defected; some entered the service of the Buyid Hasan, while others under Bajkam traveled to the Abbasid caliph in Baghdad.

In 939 or 940 the Samanid governor Abu 'Ali ibn Muhtaj attacked Gorgan; Voshmgir sent Makan aid, but the city fell after a long siege.

When Voshmgir arrived to Tabaristan, he was faced there with a revolt by his governor of Sari, al-Hasan ibn al-Fairuzan, who was a cousin of Makan and blamed Vushmgir for his death.

[4] Vushmgir, with the aid of 30,000 Samanid troops under their general Qaratakin, captured Gurgan in 945, and set forth to conquer the rest of Tabaristan.

Vushmgir's pursuit was then cut short when he was ambushed by the Buyid ruler Hasan, and forced to flee back to the Samanid border.

This time the campaign was successful: in 947, Vushmgir managed to defeat al-Hasan and expel him from Tabaristan, gaining control over the region once again.

[4] In 948 Hasan (who, since the Buyids' entrance into Baghdad, in 945 had used the title Rukn al-Dawla) invaded Tabaristan and Gorgan and took them from Voshmgir.

[5] Voshmgir was killed by a boar during a hunt in December 967, shortly after a Samanid army had arrived for a joint campaign against the Buyids.
