Tahir ibn Husayn (Arabic, Persian: طاهر بن حسين) (died 822) was a general and governor during the Abbasid caliphate. In Arabic he is known as Zol-Yamanein meaning the warrior with two right hands as he used to fight with two sword in his both hands. Taher did was a rebel and an anti-caliphate person who strengthened the independence movements which Persians had started 70 to 80 years before him. According to Majma-altawarikh he was assassinated by two mercenaries while in bed. He never served under any Caliph. Weaker unknown histories narrate that""Specifically, he served under al-Ma'mun and led the armies that would defeat al-Amin, making al-Ma'mun the caliph. He was born in Phoshang which is a village in ancient city of Herat (then Khorasan present day Afghanistan)"".
Afterwards, Tahir was made governor of the eastern Abbasid lands, effectively making him governor of Persia. Tahir later declared independence from the Abbasid empire in 822 by omitting any mention of al-Ma'mun during a Friday sermon.[citation needed] However, he died the same night and al-Ma'mun appointed Tahir's son to continue at his father's post. This established the Tahirid dynasty, which ruled a semi-autonomous state in eastern Persia.
