TAHIRID DYNASTY

The Tahirid dynasty was a dynasty of Persian origin, that effectively ruled the Khorasan from 821 to 873 while other members of the dynasty served as military and security commanders for the city of Baghdad from 820 until 891. The dynasty was founded by Tahir ibn Husayn, a leading general in the service of the Abbasid caliph al-Ma'mun. The founder of the Tahirid dynasty was Tahir ibn Husayn, a general who had played a major role in the civil war between the rival caliphs al-Amin and al-Ma'mun. He and his ancestors had previously been awarded minor governorships in eastern Khorasan for their service to the Abbasids. In 821, Tahir was made governor of Khorasan Their capital in Khorasan was initially located at Merv but was later moved to Nishapur. After the death of Tahir, the caliph then appointed his son, Talha, whose governorship lasted from 822–828. Tahir's other son, Abdullah, was installed as the wali of Egypt and the Arabian Peninsula, and when Talha died in 828 he was given the governorship of Khorasan.
