 According to H. A. R. Gibb, the expeditions against Chaghaniyan and other areas east of the Oxus river seemingly indicated “a methodical plan of conquest” of Soghdiana by Ziyad.In 705, the Arab general Qutayba ibn Muslim managed to make the Chaghan Khudah, whose name is mentioned as Tish, acknowledge Umayyad authority.The real reason for Tish's submission, however, was to gain aid in defeating the local rulers of Akharun and Shuman in northern Tokharistan, who had been making incursions against him.
