Ushrusana was brought under Abbasid control during the caliphate of al-Ma'mun (r. 813–833). In 822, a Muslim army under Ahmd ibn Abi Khalid al-Ahwal conquered Ushrusana and captured its ruler Kawus ibn Kharakhuruh; he was sent to Baghdad, where he submitted to the caliph and converted to Islam. From this point on, Ushrusana was generally considered to be part of the Abbasid state, although the afshins were allowed to retain their control over the country as subjects of the caliph. Kawus was succeeded by his son Khaydar, who is usually referred to in the sources simply as al-Afshin, giving rise to the dynastic name "Afshins".
