The first Arab campaigns to Central Asia began with the capture of Marv in 651 under the leadership of Ubaidullah ibn Ziyad. A lot of Arab expeditions to Mowarraunnahr which were in the second half of the 7th century,were organized for the purpose of plundering and exploring the region. The ultima conquest of Movaraunnahr by the Arabs began with the arrival of Qutayba ibn Muslim to the viceroyalty of Khurasan at the beginning of the 8th century. Ustrushana was not left out of such political processes and its subsequent political life consisted of struggles against the Arab caliphate's invasion campaigns, and the history of diplomatic relations like other regions of Central Asia.
