モンゴル高原
The designation "Mongol" briefly appeared in 8th century records of Tang China to describe a tribe of Shiwei. It resurfaced in the late 11th century during the Khitan-ruled Liao dynasty. After the fall of the Liao in 1125, the Khamag Mongols became a leading tribe on the Mongolian Plateau. However, their wars with the Jurchen-ruled Jin dynasty and the Tatar confederation had weakened them.
