resulted in the capture of Sebük-eri's brother Ghalib. Al-Mu'addal then campaigned in Ghazna and, together with support sent by his brother, imposed al-Layth's authority in parts of Afghanistan by the end of the year. In February 910 al-Layth left Zarang at the head of an expedition against Sebük-eri. By May he had defeated Sebük-eri on the field and released his son from captivity, and the conquest of Fars proceeded in earnest. Sebük-eri, however, was a caliphal vassal and received support from the Abbasids. Al-Layth's representative in Fars was defeated by Abbasid forces under Mu'nis al-Khadim in August, forcing al-Layth to come to terms, and he left Fars for Kerman. Sebük-eri, however, refused to make peace with the Saffarid, and with Abbasid help he defeated and captured both him and his son; al-Mu'addal managed to escape to Kerman. The captives were sent to Baghdad; al-Layth remained in prison until his death at Raqqa in 928. References Bosworth, C.E.
