Qutayba ibn Muslim
In the 8th century, Islam began to penetrate the region, the desert nomads of Arabia could militarily match the nomads of the steppe, and the early Arab Empire gained control over parts of Central Asia. The early conquests under Qutayba ibn Muslim (705–715) were soon reversed by a combination of native uprisings and invasion by the Turgesh, but the collapse of the Turgesh khaganate after 738 opened the way for the re-imposition of Muslim authority under Nasr ibn Sayyar.
