In 751, two of the greatest powers of the age squared off in the valley of the Talas River. On one side was the Abbasid Caliphate, aided by its ally the Tibetan Empire. On the other was the Tang dynasty, aided by Ferghana and some Karluk mercenaries. After several days of stalemate, the Karluks defected to the Abbasid side, causing a Tang-Ferghana rout.
What if things had gone the other way, and the Tang had won? Judging by what I've read, I doubt the immediate effects would be as dramatic as some have claimed, but I wouldn't be surprised if there were significant butterflies.
