حوض تاريم
The first inhabitants came from the west. The oldest Tarim mummies, found in the Tarim Basin, are dated to the 2nd millennium BCE, when the Indo-European Tocharians inhabited the Tarim Basin. In the first millennium BCE the Tarim Basin was inhabited by the Indo-European Yuezhi nomads. In the second century BCE the region became part of the Xiongnu empire, a confederation of nomads centered on present-day Mongolia.
