Siege of Kamarja

The siege of Kamarja was fought in 729 between the Arab Muslims of the Umayyad Caliphate and the Türgesh Khaganate, along with its Soghdian allies. The Umayyad conquest of Transoxiana had been undone in the 720s by the uprisings of the local Soghdian princes and the Türgesh invasions. By 729, the small fortress of Kamarja near Samarkand (in modern Uzbekistan) was one of the last remaining Arab strongholds in Transoxiana, when it was attacked by the Türgesh under the personal direction of their ruler, Suluk. The subsequent siege, for which a detailed account survives in the history of al-Tabari, lasted for 58 days and ended with the negotiated withdrawal of its garrison to Samarkand. The stubborn defence of Kamarja was celebrated in Arabic literature, but the Arab hold over the region was broken after the Battle of the Defile two years later. It was only following the collapse of the Türgesh Khaganate after 738 that the Arabs re-established their rule over Transoxiana.

Background

The region of Transoxiana (Arabic: Ma wara' al-nahr) had been conquered by the Umayyad leader Qutayba ibn Muslim in the reign of al-Walid I (r. 705–715), following the Muslim conquests of Persia and Khurasan in the mid-7th century. The loyalty to the Caliphate of Transoxiana's native Iranian and Turkic populations and of the autonomous local rulers remained questionable, and in 719 the latter requested aid from the Chinese and their Türgesh vassals. In response, from 720 on the Türgesh launched a series of attacks against the Muslims in Transoxiana, coupled with uprisings against the Caliphate among the local Soghdians.
