怛罗斯战役
By 750 the Tibetans had lost almost all of their central Asian possessions to the Chinese. In 753, even the kingdom of "Little Balur" (modern Gilgit) was captured by the Chinese. However, after Gao Xianzhi's defeat by the Caliphate and Karluks at the Battle of Talas (751), Chinese influence decreased rapidly and Tibetan influence began to increase again. Tibet conquered large sections of northern India during this time.
