Nasr I

With the weakening of the Tahirid governors of Khurasan at the hand of the Saffarid ruler Ya'qub ibn Layth (r. 861–879), Nasr was able to virtually rule as an independent monarch.

Nasr was the son of Ahmad ibn Asad, who ruled a significant part of Transoxiana under the suzerainty of the Abbasid Caliphate.

[1] The weakening of the Tahirid governors of Khurasan at the hand of the Saffarid ruler Ya'qub ibn Layth (r. 861–879) enabled Nasr to virtually rule as an independent monarch.

[5] In 870/1, Nasr gave shelter to the Banijurid ruler Da'ud ibn Abbas, who had fled from his domain after Ya'qub briefly occupied the city of Balkh.

With the collapse of the Tahirids, the city had fallen into a turbulent power vacuum, and was subject to repeated incursions by the Afrighid shahs of Khwarazm.
