An investigation into Quhestan's Conditions in the Third and Forth Centuries ('AH')

In the historical geography of Iran, Quhestan has a distinct identity in relation with great Khorasan. This region was of great importance during the third and forth centuries ('AH') with the increase of some symmetric governments like Tahirids, Saffarids, Samanids, and Ghaznavids and it was ruled by them successively. Among the characteristics of Quhestan which attracted anti-'Abbasid movements were its special geographical situation (being between Sistan and Khorasan), the presence of social groups (ayaran) chivalrous bandits, fighters for the faith, etc) and different religious groups (Muslims, Jews, Christians, etc) in the region.Using a descriptive –analytical method and library resources the present paper investigates the historical geography of Quhestan and its sociopolitical and religious condition at the time of these symmetric governments,.
