During the 8^th century, Fergana was the location of fierce rivalry between Tang dynasty China and the expansion of Muslim power, leading to the Battle of Talas in 751, which resulted in a victory for the Muslims and the disengagement of China from Central Asia. Two antecedent battles in 715 and 717 had seen the Chinese prevail over Arab forces. A series of Arab, Persian, and later Turkic Muslim rulers reigned over the Fergana.
