[1] Lashkari ruled Arran for fifteen years in what is described by the Ottoman historian Münejjim Bashi as a troubled reign.
[2] When he died in 1049, Anushirvan succeeded him, but he was still underage, and real power lay with the chamberlain (hajib) Abu Mansur, who served as regent.
Münejjim Bashi, summarizing a now lost local chronicle, reports that this was because Abu Mansur immediately agreed to surrender several frontier fortresses to the Kakhetians, the Georgians and Byzantines, in order "to restrain their greed for Arran".
[4][5] This decision provoked the leading men to revolt under the leadership of al-Haytham ibn Maymun al-Bais, chief of the tanners in Shamkur.
According to Vladimir Minorsky, this movement represented an uprising of the town notables against the senior bureaucratic caste.
